AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED

Embryonic Testes secrete what hormones?

Testosterone

Anti-Mullerian Hormone

Function of Embryonic Test

stimulates differentiation of Wolffian Ducts-->Internal Male Genitalia

Function of Anti-Mullerian Hormone

causes atrophy of Mullerina ducts aka Female reproductive system

Testosterone in male is synthesized by what cell type

Leydig Cells

Leydig cells are stimulated by what hormone

LH

FSH acts on what cell types

Sertoli Cells

Granulosa Cells

LH acts on what cell types

Leydig Cells

Theca Cells

Sertoli Cells function

, spermatogenisis

-secretion of inhibin

Inhibin Function

(-) feedback on FSH release

Embryo Ovaries secrete what hormones?

Estrogen

w/o Test-->No wolffian duct formation

w/o anti-mullerian hormone-->mullerian duct formation may occur

Theca Cell Functions

-Found in Theca Internal

-stimulated by LH

-Formation of Androstenedione & Test

Granulosa Cell Function

Androstenedione diffuses from Theca cell and is converted to Estradiol



FSH stimulates Test->Estradiol

FSH function in female

FSH stimulates Test->Estradiol

Also stimulates Follicle Development

What phase of the cycle is variable, Which is standard

Variable- Follicular Phase

Luteal Phase is constant

Hormones Needed for Ovulation
