Anterior Pituitary Gland
release of FSH and LH

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
Follicle Stimulation Hormone
target organ: mammary glands
parathyroid hormone; raises calcium blood levels.
adrenaline; regulates somatic system
thyroid hormone; metabolic reaction rates, protein synthesis, and development.
melatonin; regulates sleep and awake cycle.
TSH, PRL, LH, ACTH, FSH, GH
estrogen; female development, secondary sex characteristics.
ADH; help kidneys regulate water retention
oxytocin; stimulate uterine contractions.
testosterone;male development, secondary sex characteristics
