Anterior Pituitary Gland
release of FSH and LH
LH stimulates Leydig cells to make and
release testosterone into the blood.
Feedback loops; output is used as an input to initiate a response
Up regulation; increased sensitivity to specific hormone
Down regulation; decrease in receptors making cells less sensitive to hormone
