Flashcards in Anterior pituitay Deck (27):
1

What does GnRH do

stimulate LH and FSH

2

What does dopamine do

inhibit PRL

3

What does Thyrotropin releasing hormone do

stimulate TSH

4

what does somatostatin do

inhibits GH

5

What does CRH (corticotropin releasing hormone) do

Stimulates ACTH

6

What is the only strictly inhibitory hormone

Dopamine inhibits prolactin

7

What is FSH

Follicle stimulating hormone

8

What is LH

luteinizing hormone

9

What is prolactin

protein produced by acidophils of pituitary
Mammary gland development
Milk production

10

What is TSH

Thyroid stimulating hormone

11

What is PRL

Prolactin

12

What is GH

Growth hormone (somatotropin)

13

What is ACTH

adrenocorticotropin hormone

14

What is one key difference between prolactin (besides being inhibited by dopamine) and other hormones

concentrations change during life

15

What induces prolactin

Suckling

16

What does prolactin target

milk formation in milk producing cells

17

What does oxytocin act on

muscle cells

18

What happens when too much prolactin is produced

Hyperprolactinemia
tumor of adenopypophysis sometimes
Can treat with dopamine like drug

19

What are examples of glycoprotein hormones

FSH, LH,TSH

20

What is common for all glycoprotein hormones

Alpha subunit

21

What is unique to each glycoprotein hormone

beta subunit

22

What do gonaotropins do

regulate reproductive tract

23

What does FSH stimulate

Granulosa cells

24

What does LH stimulate

theca, ovulation, corpus luteum

25

What does estradiol and progesterone do to the hypothalamus and pituitary glands

Negative feedback to reduce the amount of GnRH produced which lowers the amount of LH and FSH produced

26

What does anterior pituitary produce

FSH, LH-Repro
TSH-Thyroid
PRL-Lactation
GH-Growth hormone
ACTH- adrenocorticotropic

27

What does GHRH do

stimulates growth hormone
