Document Summary

Hormones: growth spurt- hormone driven; modulate growth and development, homeostasis, reproduction, and many other things in physiome including aspects of ccn (neurodevelopment and immunity); come from other organs with a secondary secretion function (kidney) Hypothalamus- nervous signal, ghrh (neurohormone), anterior pituitary gland, gh- bone, liver (releases igf-1 to bones and muscle), muscle. Homeostasis- blood calcium and blood glucose (insulin decrease blood glucose), glucagon causes increase blood glucose. Pns along with astrocytes in cns and astrocyte-like cells in pns have receptors for many hormones (insulin, estrogen) Hormones of the pancreas- has exocrine and endocrine functions, diseases- pancreatitis, cancer. Prohibited drugs: anabolic androgenic steroids, peptide hormones, growth factors and related substances, beta-2 agonists, hormone antagonists and modulators; stimulants, narcotics, cannabinoids, glucocorticosteroids. Anabolic steroids- hormones released naturally at low levels in complex ultradian, circadian rhythms, anabolic steroids not timed to mimic natural hormone production.

From the list below, select all statements accurate with respectto hormonal regulation of steroid hormone production in males andfemales.

Question 9 options:

A)	hypothalamic secretion of GnRH stimulates LH and FSH secretionin the anterior pituitary

B)	FSH secretion in the anterior pituitary stimulates testosteronesecretion in theca cells and Leydig cells

C)	FSH secretion in the anterior pituitary stimulates inhibinsecretion by granulosa cells and Sertoli cells of the ovary andtestis, respectively

D)	LH secretion stimulates testosterone secretion in both ovariangranulosa and theca cells

E)	LH secretion stimulates testosterone secretion in Leydig andtheca cells of the testes and ovaries, respectively

F)	inhibin feeds back to turn down both LH and FSH secretion in theanterior pituitary

G)	inhibin feeds back to selectively suppress LH secretion in theanterior pituitary without changing FSH secretion

H)	inhibin feeds back to selectively suppress FSH secretion in theanterior piutitary without changing LH secretion

I)	testosterone secretion in males always feeds back to inhibitGnRH secretion from the hypothalamus

J)	testosterone secretion in males always feeds back to inhibitanterior pituitary responsiveness to GnRH

K)	progesterone in high concentration has an inhibitory effect onGnRH secretion in the hypothalamus

L)	similar to testosterone's effect in males, estrogen in femalesalways feeds back to inhibit GnRH secretion from thehypothalamus

M)	when estrogen levels in females are low, estrogen feeds back atthe hypothalamus to inihibit GnRH secretion from the hypothalamussimilar to testosterone's effects in males

N)	when estrogen levels in females are high and unaccompanied byhigh progesterone levels, estrogen is stimulatory, rather thaninhibitory to GnRH secretion in the hypothalamus

O)	if estrogen levels in females are high but are accompanied byhigh progesterone levels, the powerful inhibitory effects ofprogesterone override the stimulatory effects of estrogen andsuppress GnRH secretion from the hypothalamus
