Human Anatomy and Physiology
Human physiology is the study of the human body relevant to the functions of the organs and systems. It provides a biological baseline for the five senses including the different systems, so that the body can operate normally.
What causes bumps on the back of your tongue?
The bumps on the back of your tongue would be called your taste buds. The vallate papillae are a v-shaped row of larger taste buds at the back of your tongue. Many people don't notice these until they have a concern about oral infection and take a good look in their throat, not realizing that these prominent bumps have always been there. Take a look at the related link to see if these vallate papillae are what you're concerned about. And, whatever you're seeing, make an appointment with your health care provider for screening if you have reason to be concerned about oral infections. The normal tongue has numerous taste buds which are necessary for appreciation of taste. Those at the back are relatively larger and form prominences. These bumps are caused by underlying taste buds. how do you know for sure that they are inflammed taste buds? Couldn't it be warts on the back of the tongue? no, you could have inflammed taste buds--see a doctor for diagnosis good luck If you are talking about the big ones in a line on the back of your tongue They belong there. They are part of you taste buds, leave them alone It's possible but unlikely. Why are you chewing marijuana? Oh, you smoked it? Perhaps smoking is irritating your toungue. If it happens again, quit smoking. Pot can cause all sorts of problems, the irritation from the smoke could cause this sort of symptom. It is however, important to know that your tongue has natural bumps in the back which are larger than the bumps in the front, even though they are in fact taste buds. If you were smoking with other people you could have caught something from them... maybe strep or mono who knows... if you're worried about it go to the doctor 1 you don't necesarily have to tell him you smoked and 2 he will have to keep it confidential if you do. There is a condition called Benign Migratory Glossitis that can cause reddish bumps. Usually harmless, if it lasts for more than 10 days or so, see your doctor or dentist. Those Bumps on your tongue are called taste buds. Red bumps on the back of the tongue can be numerous things. Tastebuds tend to get larger towards the back of the tongue so this may be the case. I've had that happen to me when I ate some really hot food. If you've had penicillin lately and have red blotches on your abdomen that would appear to be an allergic reaction causing the red bumps. Sometimes doctors will prescribe a Tetracycline mouth rinse. Tetracycline is an antibiotic which would indicate the bumps are caused by bacteria. So this would be useless if you have swollen or aggravated taste buds. The best thing to do is to go see a doctor who can actually see the bumps and run tests. if you have big red bumps on the back of your tongue its an allergic reaction Sores on the tongue I believe these red bumps on the back of your tongue could possibly be either canker sores or, if you are sick with the flu, signs that you may have strep throat. Also if you recently burned yourself while drinking something too hot for your tastebuds it could have caused this. Explanations from other WikiAnswers Contributors: They could be taste buds Circumvallate papillae would be the proper name. In Chinese Medicine, red bumps on the back of the tongue may mean Kidney issues. If the bumps are big and elevated, that may be excess stress (Kidney Yang excess), which can affect sleep, mood (anxiety), and immune system. If you don't have pain or visible infection, Western Medicine may call this "normal". It's possible. See the related questions link.
Is drinking too much water toxic?
Yes, drinking too much water can be toxic - except it is very hard to drink too much fresh, clean water to be able to die. Normal healthy people would need to drink on the order of 20 liters per day for it to be toxic but people with some medical problems, particularly the elderly and very young, can get toxic on much lesser amounts. Also people with psychiatric disorders, most notably schizophrenia. Drinking too much water is called polydipsia. This, as well as several other processes, can cause low blood concentrations of sodium, which is known as (dilutional) hyponatremia.
Why do babies have more bones than adults?
Over the course of childhood and adolescence, many bones in the skull and pelvis fuse together. These are the largest and widest parts of a baby's body, having them composed of several loosely connected bones permits them to flex more during birth, making the process easier on both mother and baby. In adults it is more important for these same bones to be hard and strong, so by then they are mostly fused into a small number of larger bones. It depends on how you define "bone". In absolute terms, we are born with the same number of articulated skeletal members as we have throughout our lives; however, at birth some of these "bones" have only begun to ossify, such that they wouldn't show up on an X-ray. To ossify is to "turn to bone." Anatomically, this refers to depositing calcium in the cartilage to make it harder. Since X- rays show only calcified bone, uncalcified cartilage won't show up, even though that part of the skeleton is there and fully functional. So, if you restrict "bone" to mean "only those calcified bits of the skeleton that show up on X- rays," then newborns have fewer bones. If, on the other hand, you refer to a each skeletal member as a "bone," then newborns and adults have the same numbers. Because as you grow older some of your bones grow together to form single ones. Infants have three separate bones in their skull when they are born. The areas between these bones remain soft prior to birth, allowing the skull to remain malleable so it may pass through the birth canal more easily. These bones naturally fuse as the baby grows, becoming a single bone by adulthood.

Why do men like breasts?
Men like breasts for a variety of reasons, both subconscious and conscious. They are aesthetically pleasing, they are a sign of fertility and they are just generally nice. See related links for more info. Answer It is part of the natural sex drive. Most (not all) guys are drawn to what represents a sexually healthy female. It is a hard wired as part of the instinctual human need to reproduce. Answer: It probably has something to do with a subconscious love that comes from them being a food source for some babies. Answer: Guys are visually stimulated and since the breast are often thought of as a sexual item it stimulates guys. Answer: In our society they are slightly forbidden so that makes them exciting. They simply look great on a girl. Answer: Simply because they're part of what makes up attraction towards a girl. Looking at them is just enjoyable for most men. Touching them is connected to enjoyment in several different ways. There may be an instinct to touch things that look nice or, in case of stroking and caressing them, finding pleasure in the intimacy and in giving pleasure to the girl. The main reason is that if you have big breast some guys cannot stop looking at them right? Well the reason is that they get turned on easily from looking at them because they know if they get a chance to have sex with you they will want to do more than just stare. Answer: Some people think it has to do with being breast fed as infants, they find them comforting as it reminds them of their mother's nursing. However, this doesn't exactly hold up since not all infants are breastfed. It's probably more instinct than anything. Some say it is mostly aesthetic appeal. Just like girls tend to prefer their men with some muscular definition because it is more interesting, men tend to prefer women with breasts because it is more interesting. Personally, I think that it's more because men don't have breasts. Since they lack them, they find them more interesting. There may also be a latent anthropological factor in that breasts may be an indicator of a woman's ability to provide for a newborn baby. Answer: The reason men like to look at and touch women's breasts is very simple, and is to do with our survival instincts. Breasts are a secondary sexual characteristic of human females: that is, they aren't essential to reproduction but they play a part in distinguishing between the appearance of the sexes, and so are important in attracting a mate. Men's extra height, heavier build, beards and body hair play a similar role. Animals look for signs that a potential mate will breed successfully: in women, breasts and wider hips are features which indicate a woman is ready and equipped for childbearing. Naturally-produced scents also signal to both sexes that the potential partner is healthy and ready for breeding. This isn't some ancient precursor to modern sexual attraction: it is sexual attraction; it has never changed. There's no point, as far as any species is concerned, in taking a mate who cannot reproduce or doesn't appear likely to live long enough to raise young, so all animals - not just humans - as they mature, develop ways to indicate they are a good investment in the future of the species. As cultures become more sophisticated - and this goes back to the earliest days of mankind - people devise ways to enhance their secondary sexual characteristics; to make themselves appear more attractive, more noticeable, to a potential mate. It's that simple. It is because they represent sex. A few of guy's have said... 1. Taste good. 2. Fun to Squeeze. 3. They bounce when girls run. 4. It make them think about sex 5. Guys instinct They might not be the only reasons. Breasts are a part of what makes up a guy's attraction towards a girl. Looking at them is just enjoyable for most men. Touching them is connected to enjoyment in several different ways. Those can be for example simply calming the urge to touch things that look nice or, in case of stroking and caressing them, finding pleasure in the intimacy and in giving pleasure to the girl. Answer - Subconscious jealousy that they don't have it. - Genetic program in the man's mind to allow for reproduction. - It is awesome to them. You get a sexual feeling on how they look and they sometimes like to drink milk. Men have their fetishes just like everyone else, and some men like boobs. Because they compliment the beauty of the female being...or is it because they are just awesome ( they look good and feel even better ).
What are the pressure points on the body?
The American Heart Association has distinguished 11 known pressure points on either side of the human body. In diagnosing Fibromyalgia, doctors check eighteen specific points on the body, if the patient has eleven of the eighteen causing them pain, then they are diagnosed as having fibromyalgia. Traditional Chinese Medicine (TCM) has defined hundreds of points on the body, though less than 100 are used in regular therapy. There are also what are called endangerment points that are in areas that have nerves and blood vessels. These areas require special training in order to use them therapeutically or as a form of self defense. There is no way to know how many pressure points are in the body. Pressure points differ from each person. A muscular person would be more prone to pressure points than an obese person, and just striking or holding a pressure point might not be enough. Self-defense Answer A pressure point can typically be found at any space between bones. Pressure Points: When a person is severely cut and begins to bleed, it is time for quick action. First air for severe bleeding involves applying pressure over the wound. Sometimes it is possible to press the artery above the wound against the bone behind it, and stop the bleeding. This place is called a pressure point. A pressure point is also an excellent location to take a person's pulse. Understanding Pressure Point Strikes: Striking to a hyel does not necessarily immediately knock a person out or cause a body part to become instantly numb, as has been propagated by many martial arts charlatans. Self-defense may be understood by the analogy of a body part that has fallen asleep, when proper circulation has been cut off from it. When applying forced pressure to specific hyel, your goal is not to magically tender your opponent lifeless. What you are planning to achieve is both short term and long term interruption of your attacker's energy. A listening carefully pressure point strike is initially accomplished by focusing your energy. The Important Pressure Points for Hemorrhage: The loss of a small amount of blood will cause no problem for a healthy adult, but loss of one liter or more of blood is life-threatening. The first step to control bleeding is the application of direct pressure to the wound using a clean cloth. An assisting person should wear gloves to protect from blood-borne diseases. A bleeding extremity should be elevated above the level of the heart. In cases of severe, persistent bleeding, application of pressure where a local artery can be pressed against a bone slows the bleeding. The most important of these "pressure points" are the following: The facial artery, which may be pressed against the lower jaw for hemorrhage around the nose, mouth, and cheek. One can feel the pulse of the facial artery in the depression about one inch anterior to the angle of the lower jaw. The temporal artery, which may be pressed against the side of the skull just anterior to the ear to stop hemorrhage on the side of the face and around the ear. The common carotid artery in the neck, which may be pressed back against the spinal column for bleeding in the neck and the head. Avoid prolonged compression, which can result in lack of oxygen to the brain. The subclavian artery, which may be pressed against the first rib by a downward push with the thumb to stop bleeding from the shoulder or arm. The brachial artery, which may be pressed against the arm bone by a push inward along the natural groove between the two large muscles of the arm. Hand, wrist, and forearm hemorrhage will be stopped by this pressing. The femoral artery, which may be pressed to avoid serious hemorrhage of the lower extremity. It is important not to leave the pressure on too long, as this may cause damage to tissues, including nerves supplied by arteries past the pressure point. Um, another good question. Well there are a lot of them so it depends on the person you are striking and how precisely you hit their pressure point. For example there is one called ''stomach point nine'' you have to hit this point with your finger with over 20 pounds of force to activate it properly.

What is a group of organs that work together called?
Two or more organs work together to form an organ system. Various types of organ systems include the skeletal system, the circulatory system, the muscular system, the digestive system, the endocrine system, and the respiratory system. Functions of digestive system are procuring , mastication ,digestion and absorbing the food that we eat. What we can't digest is eliminated as waste. The organs in the digestive system include oral cavity , pharynx, esophagus, stomach, small intestine, large intestine. The Human Organ Systems are: (in brief) Integumentary System: Skin. Largest organ system. Protects, regulates body temperature, holds water, excretes waste, has sensory receptors, and synthesizes biochemicals. Skeletal System: Bones. Attach to muscles, protects, structure, produces blood, store salts, and houses blood vessels/nerves. Muscular System: Muscles. Movement, structure, heat, controls heart. 3 Types: Skeletal, cardiac, and smooth muscle. Nervous System: Controlled in the brain, sensors throughout the entire body. Provides feelings, thoughts, movement, consciousness. Afferent and efferent fibers. Endocrine System: Secretes hormones. Cardiovascular System: The heart. Transports blood and oxygen around the body. Excreting wastes. Lymphatic System: Takes excess fluids, transports fluid, absorb fats, attacks foreign cells/cancer/toxins. Respiratory System: Lungs, nasal/oral cavities. Supplies oxygen to the body. Urinary System: Kidneys, ureters, bladder, urethra. Removes wastes from body, maintains water concentration. Reproductive System: Males- penis, testes, and sperm. Female: vagina, ovaries, eggs, breasts. Levels of Organization (smallest to largest): Atoms: smallest form. Molecules: bonded atoms. Macromolecules: completely bonded molecules. Cell: basic structure of life. Organelles: many cells which are specialized. Tissue: organelles which have the same function come together. Organs: Tissues which come together to form specialized functions. Organ System: A group of organs working together. Organism: A full being made up of many organ systems.

How hard is it to get a rock hard six pack on a girl?
There can be a lot of varying factors when it comes to muscle building from family genetics. Genetically my family has always had a low body fat percentage (around 6-8%) so I almost naturally have a six pack, but some families have a high natural body fat percentage, that doesn't mean they cant have a six pack it just means they will have to work a little bit harder to get it. Girls can have a harder time because they don't have high testosterone like men do and that can be a factor. Diet also plays an important roll, If you eating a lot of calories though out the day you better burn them off. Cadio is one of the most important things to achieving a six pack, it keeps your fat percentage down and makes your leg and core muscles more toned (which is what six pack really is). Also it is important to keep a work out routine and stick to it. Over all it can be challenging but all it really requires is persistence.

What is a half human half robot called?
This is what we call a cybernetic organism, or commonly "cyborg" for short. Cyborgs are humans who are also partially robots. In science fiction, humans who suffered severe injuries could be "repaired" with robotic spares. In real-life, it is actually a viable and possible resolution for humans who are missing limbs, organs and other parts. The pacemaker for example could technically be cyborg-ish. In the future it might be possible to replace broken human body parts with robotic equivalents, made easier by the invention of 3D printing.

Is HF dangerous for human?
If you mean hydrogen fluoride, that depends on how much you're exposed to at once. The first rule of toxicology is that the dose makes the poison. That being said, the lethal dose at which 50% of test animals die of HF exposure is about 1.3 grams per kilogram of body weight in rats when consumed orally. HF is generally classified as "very toxic" and "corrosive", and is considered an extreme occupational hazard for anyone who works with it.

What can cause a swollen uvula?
It will swell due to local trauma, inflammation and allergic reaction to food It could be you are sick. Or it could be that you are dehydrated. If you sleep with your mouth open and snore you can irritate your uvula. A list of other things which irritate your uvula would be drinking, smoking, dehydration. The best cure is ice-cream and lots of beverages. The swelling should go down in 8 to 12 hours. If it does not you should seek medical help. acid chronic allergic attacks like rhinitis will enlarge the uvula, which can touch the back part of the tongue causing a gagging reflex It means something is producing toxins that are affecting the uvula. I suggest you go see a doctor right away, because it could be a virus or a bacterial infection. *TIP* Try to gargle (NOT SWALLOW!) bicarbonate of soda; one spoonful dislve in water. Good Luck! :D This can happen with tonsillitis or strep throat, indicates an infectious or inflammatory process has affected this tissue. You could have a yeast infection. go see you gynecologist. This morning I woke up with a swollen uvula. I thought it was partially detached. I went to the emergency room and discovered it was either a bacterial or viral infection (possibly related to strep). I was given a prescription for penicillin.
