Question

5. What is true about the anterior pituitary gland?

A. there are different types of endocrine cells found there that produce different hormones

B. all hormones are released from the anterior pituitary through the hypothalamic-hypophyseal portal system

C. this gland produces LH and FSH which are both amine hormones, known as gonadotropins

D. the levels of most of these hormones are controlled by a positive feedback loop

Answer 1

Answer:- (A) there are different types of endocrine cells found there that produces different hormones

Explanation:- anterior pituitary gland has 5 types of endocrine cells producing 6 types of hormones,they are-

1. Somatotropes - growth hormone

2. Lactotropes - prolactin

3. Gonadotrophs - FSH and LH

4. Thyrotropes - TSH

5. Corticotropes - ACTH

All hormones are not only released by anterior pituitary but also released by posterior pituitary like oxytocin and vasopressin.

LH and FSH are glycoprotein hormones.

Levels of most of the hormones are controlled by both positive feedback and negative feedback loop.
