Hormones are biochemicals produced by the glands in a body. Hormones help to regulate the body's functions. They control hunger, mood, sleep, growth, and a number of other functions.
Asked in Human Anatomy and Physiology, Hormones
Which gland secretes epinephrine and aldosterone?
Aldosterone is secreted by the adrenal cortex in the adrenal gland - more specifically, in the zona glomerulosa. The adrenal gland is located right above your kidneys. It's normally depicted in most images by a yellow triangular shaped object that sits atop both the left and right kidneys. Epinephrine or adrenaline is secreted by adrenal medula.

Why do I wake up five minutes before my alarm clock goes off?
Your body is so skilled at regulating when you’re supposed to be awake that, if you follow a consistent schedule, it gets pretty good at beating your alarm and letting you wake up more gradually. Certain stress hormones in your brain increase during the day and decrease at night. As the cruel alarm approaches, those hormones increase steadily from their nighttime levels to their daytime ones, waking you up slowly and naturally. If your alarm interrupts this process, the body learns to start increasing those hormones earlier so it doesn’t get jarred awake. Waking up a few minutes before your alarm goes off typically means you’re getting a good amount of sleep, and your circadian rhythm is doing a good job.

What happens if you drink a bit of insulin?
nothing when my little brother learnt how to undo zips he got into my bag and sucked insulin fron a cartridge and when we took him to hospital and they told use that your stomach acid is stronger than insulin and will destroy it before it can have any affect on you ------- That is perfectly true. Insulin is a type of protein (a hormone), and as all the other protein, insulin is broken down into amino acids (which make up the proteins), started in the stomach, finished in the small intestine. It is absorbed from the small intestine for further use in the body. Once it is broken down, it becomes just a number of harmless amino acids. That is the reason why insulin has to be injected. If it goes through digestion it is no longer a 'hormone'; it loses all the function of an insulin hormone has, including its affects on blood glucose.

What is the stimulus for renin?
Renin can be upregulated in two ways: Macula densa cells in the early distal tubule of the nephron communicates with the juxtaglomerular cells of the afferent arteriole in the kidney. When the macula densa cells detect low levels of sodium, it will communicate that to the juxtaglomerular cells and in turn that will stimulate the production of renin. This is the glomerular tubular feedback system. The second way it can be stimulated is by the somatic nervous system directly. When the baroreceptors detect a drop in pressure they will stimulate your SNS and inhibit your PNS. This has several cardiovascular effects in addition to stimulating renal nerves that will upregulate more renin from the juxtaglomerular cells.

What are the symptoms of severe insulin resistance?
Why do you have to inject insulin?
Insulin currently cannot be taken by mouth, because it is a protein, and the gastric juices in the stomach would destroy it. So by injecting it under the skin, you are enabling the insulin to eventually get into the blood stream without having it get destroyed in the stomach. There is considerable research going on to try to resolve this problem--studies are ongoing to develop a pill form.

How does oxytocin cause water intoxication?
Oxytocin and another hormone, ADH (anti-diuretic hormone) are very similar in structure. If there is too much oxytocin present in the blood it can begin to act like ADH. The job of ADH is to induce the kidneys to produce less urine and help the body retain more fluid. So too much ADH activity leads to volume overload, also known as water intoxication.
What effect does Adderall have on cortisol levels?
Adderall usually raises cortisol levels. Most substances or experiences which trigger fight or flight type responses like stimulants will do this. ADHD and other illness that are treated by Adderall are thought to involve disruptions in the HPA axis. For most real ADHD sufferers this increase in cortisol is thought to cause improvement in symptoms and it is rare that someone without abnormal adrenal function experiences high cortisol (Cushing's) symptoms.
