Hormones
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.

What is the effect of prolactin at the target site?
It works on mammary gland.It stimulates the production of milk.
That can cause diabetes insipidus.
Sir Frederick Grant Banting with the help of Charles Best discovered insulin. (not spelt insuline)
Androstenedione acts like a steroid once it is metabolized by the body and can pose similar kinds of health risks. People produce androstenedione naturally during the making of testosterone and estrogen.
Do insulin-dependent diabetics ever inject themselves with glucagon or cortisol?
Glucagon, yes. Cortisol, probably not. Glucagon raises blood sugar. Many type one diabetics own glucagon injectors, so that when their blood sugar goes too low they (or someone with them) can inject them with glucagon. Cortisol does raise blood sugar, but it is not used to raise blood sugar. It's used to treat many other diseases, but not the low blood sugar which type 1 diabetics sometimes get.
Yes, But it is a local hormone; that means it is released locally to exert its effect. Not like normal hormone which are released some where far away and shows their effect some where else.
Why is adrenaline used in the treatment of an asthma attack?
Adrenaline is used because it quickly opens up the airways.
How does increased aldosterone secretion increase blood pressure?
Your body can be divided up into a number of compartments, the first two being the intracellular and extracellular compartments. The two compartments contain fluid referred to as intracellular fluid (ICF) and extracellular fluid (ECF). By convention, blood is considered part of the extracellular compartment, so it contributes to ECF. One of the major determinants of blood pressure is the volume of blood in the blood vessels. All other things being equal, if you raise blood volume, you raise blood pressure; conversely, if you lower blood volume, you lower blood pressure.
Since the blood is in the extracellular compartment, the blood volume is a component of the extracellular fluid. Therefore if you raise ECF, you raise blood volume; as we saw above, raising blood volume raises blood pressure. How aldosterone contributes to blood pressure is via the regulation of ECF volume.
Sodium (Na) is the major cation in the ECF. Sodium is very important for the nervous system and other parts of the body; consequently, the body works very hard to keep the blood concentration of sodium within narrow limits. If suddenly the amount of sodium in the blood were increased, your brain would trigger the sensation of thirst; you would drink water and increase the ECF volume to dilute the sodium and bring it back within the normal range. So by adding extra sodium to the blood, you increase ECF volume. And what happens to blood pressure? It increases, because ECF is a major determinant of blood pressure.
What does this have to do with aldosterone?
Aldosterone is a steroid hormone that's synthesized by the adrenal gland. It acts on the kidneys to increase sodium reabsorption. Having more aldosterone around means that more sodium ultimately winds up in the blood, activating thirst mechanisms that cause you to drink water, which increases ECF volume and therefore increases blood pressure.
You might be interested to know that the body really does use aldosterone to regulate blood pressure. When blood pressure drops, the kidneys sense a subtle change in blood flow and start secreting an enzyme called renin. Renin works through a pathway called the renin-angiotensin-aldosterone system (RAAS; see link at left) to ultimately increase aldosterone secretion in order to return blood pressure to normal.
It's a "piss take"
People get stressed out and can crap themselves when scared and under pressure and at the same time your body releases adrenalin to help your system cope with the "ordeal"
Ergo adrenalin is brown!
Which anti cortisol supplements work best?
I am using a high quality omega3 supplement for lowering my cortisol levels and it works very well for me. There is scientific proof for this as well. See cortisolsupplement.com
What is leptin Weight Loss Coffee?
It is grown in the mountains of Central America. It can consume much of the body fat and can rapidly lose weight. It is a very good drink not only for those who want to lose weight but it is also a refresher.
What roll does the decrease of progesterone and serotonin and dopamin play in PMS?
I know for sure that increased serotonin and dopamine make a person happy so a decrease would definitely cause the symptoms attributed to PMS.
What happens to insulin during gastroenteritis?
During gastroenteritis and food posioning absorption of glucose from the digestive tract is decreased due to vommiting, diahorrea etc.
If the blood sugar levels are lower that the pancreas will respond by producing less insulin and more glucagon to ensure blood glucose levels are maintained at an adequate level.
Those suffering from type 1 diabetes should, therefore, reduce their insulin intake to avoid becoming hypoglycaemic
congential adrenal hyperplasia
It can be used if you are going into anaphylaxis- a really bad allergic reaction. It is also used in heart-related emergencies, like with Ventricular tachycardia or fibrillation, or to try and restart the heart in asystole.
What does gastrin control in the body?
Gastrin is a hormone in the stomach which is released in the presence of food and causes the release of hydrochloric acid (HCl).
What is the difference between regular insulin and sliding scale insulin?
Regular insulin is generally basal and bolus i.e a basal rate that runs 24 hours and a bolus that deals purely with carbs eaten. sliding scale is a programme where a fast acting insulin is released at a rate per hour constantly and increased only when carbs are injested. Generally sliding scale is used during a surgical proceedure when you are starved. It ensures your body gets the correct background insulin when no bolus is required.
