PSYC 385 Lecture Notes - Lecture 5: Aromatase, Gonadotropin, Autocrine Signalling
Document Summary
Chemical signaling: paracrine: local (cells can communicate, autocrine: leaves cell and receives itself, endocrine: through bloodstream which allows for long distances (in terms of where the hormone goes) Classes of steroid hormones: androgens (ex. testosterone, estrogens (ex. estradiol, glucocorticoids (ex. cortisol) All under the class of hormones that begin from cholesterol. Hypothalamus connection to pituitary and gonads: hypothalamus: releases gnrh (gonadotropin releasing hormone, signals pituitary gland to release fsh (follicle stimulating) and lh (lutenizing, gonads: ovaries and testes (make testosterone and estradiol) Testosterone and estrogen are one chemical change away. Women have higher concentration of aromatase (enzyme) in their ovaries. Men have 10x the level of testosterone that women do in their blood. (also in the photo it can go to the ovaries and release: estradiol: one form of estrogen (has an alcohol attached (transforms more testosterone into estradiol) estradiol. Collect hormone levels from saliva instead of through to it) needles.
