Hormones released from the Hypothalamus

Question 1

Corticotropin-releasing hormone (CRH)

Answer 1

Corticotropin-releasing hormone (CRH) → ACTH in AP → adrenal cortex → cortisol

Question 2

Gonadotropin-releasing hormone (GnRH)

Answer 2

Gonadotropin-releasing hormone (GnRH) → FSH and LH in AP → gonads → androgens and estrogens

Question 3

Growth hormone-releasing hormone (GHRH)

Answer 3

Growth hormone-releasing hormone (GHRH) → GH in AP → liver (or just many tissues) → IGFs

Question 4

Growth hormone-inhibiting hormone (GHIH)

Answer 4

Growth hormone-inhibiting hormone (GHIH) –| GH release in AP

Question 5

Prolactin-releasing factor (RPF)

Answer 5

Prolactin-releasing factor (RPF)→ prolactin from AP → breast tissue

Question 6

Dopamine/Prolactin-inhibiting factor (PIH)

Answer 6

Dopamine/Prolactin-inhibiting factor (PIH) –| prolactin release in AP

Question 7

TRH

Answer 7

TRH → TSH (and prolactin) in AP → thyroid gland → thyroid hormones

Question 8

effect of somatostatin on GH?

Answer 8

inhibitory

Question 9

how does the hypothalamus communicate?

Answer 9

The hypothalamus transports hormones down the axon and stored in the nerve endings for the posterior pituitary. The anterior pituitary communicates via the hypothalamic-hypophyseal portal system. Secretion of hormones is in pulses and at certain times during the day.
