What’s the function of GnRH and what organ secrets it?

A

Hypothalamus: Stimulates the Anterior Pituitary to Release LH & FSH

23
Q

What is the function of LH & FSH

A

LH: aka ISH Stimulates interstitial endocrine cells to release testosterone

FSH: Stimulates Nurse cells to release androgen-binding proteins that bind to Test, Keeping it in the Seminifrious Tubules to stimulate Spermogenisis

24
Q

What’s the function of Testosterone?

Inhibin?

A

General Body Growth

Secreted from Nurse Cells, Supresses FSH reducing Sperm production without reducing LH and testosterone secretion.

25
Q

Basics of Spermatogenesis

Meiosis

A
  1. Division of Large Germ cells into smaller germ cells with flagella.
  2. Reduction of 1/2 the sperm cells
  3. Shuffling genes so each chromosome contains different properties than the parents

MEIOSIS: Recombines genes and reduces chromosomes while producing 4 daughter cells that will become sperm.o
