Gastrin is a hormone in the stomach which is released in the presence of food and causes the release of hydrochloric acid (HCl).

Is gluconeogenesis the prime metabolic effect of cortisol?

Yes, gluconeogenesis is considered one of the primary metabolic effects of cortisol.

Cortisol, a glucocorticoid hormone secreted by the adrenal cortex, plays a key role in maintaining blood glucose levels, especially during fasting or stress. Its main metabolic action is to stimulate gluconeogenesis, which is the production of glucose from non-carbohydrate sources like amino acids and glycerol in the liver.

Other important metabolic effects of cortisol include:

Protein catabolism: Breakdown of muscle proteins to provide amino acids for gluconeogenesis

Lipolysis: Mobilization of fat stores for energy

Inhibition of peripheral glucose uptake: Acts as an anti-insulin hormone, reducing glucose uptake in muscle and adipose tissue

Promotion of glycogen synthesis in the liver despite its hyperglycemic effect

While cortisol has multiple metabolic actions, gluconeogenesis is considered its hallmark effect, particularly during periods of physiological stress or starvation.

You have 8.5 progesterone level at 5 weeks pregnancy you have been put on Progesterone supplement Can you carry a full term pregnancy with a progesterone supplement?

It's very promising. You should be given progesterone supplements in the form of vaginal suppositories, which is suppose to be the most effective method.

A tropic hormone is any hormone that?

Hormones that target other endocrine glands. Produced by anterior pituitary. Include: FSH, TSH, LH, ACTH.

Is antidiuretic hormone an anterior pituitary hormone?

Anterior Pituitary Makes:

1. Growth Hormone which affects bones & muscles to produce growth.

2. Prolactin which affects the breast for milk secretion.

3. Adrenocorticotropic Hormone which affect adrenal glands to

(a) make aldosterone which affects the kidney to cause it to conserve sodium.

(b) to make cortisol which affects body cells causing stress.

(c) to make androgens which affect the axilla producing hair growth.

4. Thyroid hormone which affects the thyroid to make thyoxine. This acts on body cells and increases metabolism.

5. Gonadotropic Hormones (LH, FSH) which affect the testes causing them to make testosterone. This in turn affects body cells producing male secondary sex

characteristics. This same hormone affects the ovaries to make estrogen which again affects body cells which in turn produce female secondary sex

characteristics. Both males and females make these two sex hormones.

The third effect is on the ovaries to make progesterone which acts on the uterus to maintains pregnancy.

Post Pit makes:

1. Oxyotocin which acts on the breast to cause the breasts to "let down" milk. It also causes the uterus to contract.

2. Antidiuretic hormone which acts on the kidney to conserve water
