Hormones

Glucagon promotes gluconeogenesis (the synthesis of glucose, mainly in the liver) and antagonizes (blocks) the effects of insulin (which pushes sugar into cells). This can lead to hyperglycemia in states of glucagon overproduction, such as in glucagon producing tumors.

1. constrict arterioles thus increase blood pressure,

2. stimulate ADH secretion from the anterior pituitary which increases water retention by the kidneys and also increases blood pressure, and

3. stimulate aldosterone secretion from the adrenal cortex which increases sodium retention in the kidneys leading to more water retention by the kidneys and helping to increase blood pressure too.

Adult: 10--200 pg/ml (4.8--96 pmol/L)

Child: 5--125 pg/ml (2.4--60 pmol/L)

I Know that progesterone causes breast development, and the more progesterone, the larget breasts. I also know that after firtilization occurs, the follicle produces high levels of progesterone. So, I do believe that progesterone also causes the mamory glands to produce milk several months into pregnancy.

i just did this experiment in class today. what you need to do is add water to the milk. but you have to keep the same amount of milk in all of them. this is if you are testing the effect of substrate concentration on renin. so you have one experiment with 8ml of milk and then one with 6 ml of milk and 2 ml of water and 4 ml of mik and 4ml of water and so on ... be carefful to stir the solution a bit i hope this helps

Adrenaline can help mobilize fat stores for energy during fight-or-flight responses, but it does not directly burn fat on its own. It activates receptors on fat cells, releasing fatty acids into the bloodstream, which can be used as fuel by the body. Factors like exercise and diet play a more significant role in fat burning.

The cortisol stimulation test, also known as the cosyntropin stimulation test, is a medical test used to diagnose adrenal insufficiency. It involves measuring the cortisol levels in the blood before and after the injection of cosyntropin, a synthetic form of adrenocorticotropic hormone (ACTH). This test helps assess the ability of the adrenal glands to produce cortisol in response to stimulation.

Gastrin, secretin, and cholecystokinin are examples of hormones that play roles in the regulation of the digestive system. Gastrin stimulates gastric acid secretion, secretin stimulates pancreatic bicarbonate secretion, and cholecystokinin stimulates gallbladder contraction and pancreatic enzyme secretion.

Angiotensin II has 4 effects: (overall effect is to increase Blood Pressure and Blood Volume)

-

1. The adrenal cortex (Zona Glomerulosa)

2. Triple effect on the Nervous System

3. Supraoptic nucleus of the hypothalamus

4. Vasoconstricts smooth muscle

-

1. There are Angiotensin II receptors in the Zona Glomerulosa - stimulates release of Aldosterone

-

2. Direct effect on the sympathetic nervous system, increasing output. Second effect on postganglionic nerve endings inhibiting the reabsorption of Norepinephrine (i.e. increasing concentration of neurotransmitter - increasing stimulation). Third effect on reception of tissue to NE.

-

3. Stimulates Supraoptic nucleus to release Anti Diuretic Hormone

-

4. Direct effect on smooth muscle of a. venous system (increasing venous return, stroke volume and therefore contractility of heart muscle and cardiac output - increasing systolic blood pressure). b. arterial system (increasing resistance to blood flow, and increasing diastolic blood pressure).

Excess adrenaline can trigger atrial fibrillation in some individuals, particularly those with underlying heart conditions. Adrenaline can increase heart rate and put stress on the heart, potentially leading to irregular heart rhythms like atrial fibrillation. It is important for individuals experiencing symptoms to consult with a healthcare provider for proper evaluation and management.

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. It travels through the bloodstream to various tissues and organs in the body, where it helps to facilitate the uptake and storage of glucose for energy production.

Parathyroid hormone helps regulate calcium levels in the body by increasing the amount of calcium in the blood. It does this by stimulating the release of calcium from bones, increasing the absorption of calcium from the intestines, and reducing the excretion of calcium by the kidneys.

To improve the last answer, adrenaline is a drug that your body produces which I believe last about a minute to two minutes, but also depends on the amount of shock you undergo.

The effects will be as long as you are under an adrenaline rush. As soon as the rush wears off, your body gets a noradreanaline (Impove the spelling, if needed.) shot, and, right away, the effects of adrenaline will wear off. I hope this answers your question?

Hormones are chemicals produced by the body's glands that travel through the bloodstream to regulate various physiological processes such as metabolism, growth, and reproduction. They all act as chemical messengers, binding to specific receptors on target cells to initiate a response and maintain homeostasis in the body.

I am reviewing a paper for JEP that says the oxytocin like activity from a plant of Ficus family. Interestingly I was searching some works for that review, when I came accross this question. I will do some study and for some one interested do contact the JEP or krishnakaphlevet@yahoo.com for specific queery.

Aldosterone stimulates the reabsorption of Na in the kidney by increasing the activity of the Na+/K+ ATPase pump in the distal convoluted tubule and collecting ducts, which pumps Na+ out of the tubular lumen and into the blood. Additionally, aldosterone increases the expression of epithelial sodium channels (ENaC) on the luminal membrane of tubular cells, facilitating Na+ reabsorption.

Vasopressin is typically measured in international units (IU), not milligrams. The conversion factor between units and milligrams may vary depending on the specific formulation of vasopressin being used. It is important to consult a healthcare provider or a pharmacist for accurate dosing information.

Insulin is always used for the treatment of insulin-dependent diabetes mellitus (type I diabetes) and occasionally also for the treatment of therapy refractory non-insulin-dependent diabetes mellitus (type II). This therapy is obligatory for individuals with ketoacidosis and it can be taken into consideration for all subjects who remain symptomatic, lose weight, or have continuously high blood glucose concentrations (in fasting state more than 7-8 mmol/l, postprandial more than 10-12 mmol/l) despite another treatment. Insulin can also become temporarily necessary during surgical interventions or acute diseases.

Human plasmids introduced into the bacteria stimulate insulin production.

A special enzyme is used to cut out the insulin gene from a human cell. It is attached to a bacterial chromosome which is also split open by an enzyme. The gene is then transferred into a bacterial cell. The gene makes the bacterial cell produce insulin.

Insulin is secreted when blood sugar rises. It works by stimulating receptors on tissue cells to escort glucose into the cells. It all suppresses glucagon, hormone-sensitive lipase (a hormone responsible for mobilizing and using fat stores) and suppresses the appetite centers in the brain.

Glucagon is secreted when blood sugar is low. It triggers gluconeogenesis in the liver, which means that fats and proteins are converted into glucose and released into the blood. It also is responsible for mobilizing glycogen stores, suppresses insulin, and mobilizes fat stores.

So glucagon and insulin not only do opposite things, they are antagonistic to each other, meaning when one is high the other one is low. They do not technically work "together".

High levels of insulin are common in those who consume excessive calories and excessive carbohydrate foods. For those who are sensitive to the effects of insulin, this can cause reactive hypoglycemia and obesity.

islets of langerhans. tho i guess all cells have the ability to produce insulin.

To lower DHT levels in the body, you can consider taking supplements like saw palmetto or stinging nettle root, incorporating foods rich in antioxidants and zinc into your diet, reducing stress levels, and avoiding products or behaviors that can increase DHT production, such as anabolic steroids or excessive alcohol consumption. It's important to consult with a healthcare provider before making any significant changes to your DHT levels.

Antidiuretic hormone (ADH) decreases the amount of sodium in your body and when ever sodium levels go down potassium levels go up (same is true for visa versa) so the amount of Potassium should increase when there is an increase in ADH.

The function of insulin is too maintain the blood glucose level. So, really, it controls the level of sugar in your body. People with diabetes have trouble controlling their blood glucose level as their insulin doesn't work very well. People with Type 1 Diabetes have to take insulin medications, while people with type 2 diabetes can control their blood glucose levels with diet.
