2

What does the TSH stand for? What is the target tissue?

THYROID STIM. HORMONE, the thyroid

3

What does tropic mean?

Tropic HORMONES turn on *other* ENDOCRINE GLANDS to release more/other HORMONES

Is ACTH tropic?

Yes

8

What is the F of ACTH?

16

Is FSH tropic in females? Males?

Females = Yes

...the NEUROHYPOHESIS

25

What does OT stand for? What is the target tissue(s)?

OXYTOCIN, mammary glands and uterine smooth muscle

26

Is OT tropic?

No

27

What is the F of OT?

F - Mammary gland = Stim. milk ejection
F - Uterine smooth muscle = Stim. uterine contraction to return to regular size

28

What does ADH stand for? What is the target tissue?

ANTI DIURETIC HORMONE, kidneys

29

Is ADH tropic?

No

30

What is the F of ADH?

F - Inc. water retention/reabsorption, vasoconsriction

31

What is the role of the HYPOTHALAMUS in regulating PITUITARY function?

The HYPOTHALAMUS releases tropic HORMONES, so it triggers the release or inhibition of HORMONES in the ANTERIOR or POSTERIOR PITUITARY GLAND. The HYPOTHALAMUS produces and release OT and ADH by firing APs
