Document Summary
Vision: ex: male peacocks with prettier colors (etc. ) are likely healthier. Hormones: travel via blood stream to entire body. Released via pituitary and adrenal glands after triggered by pathway: work slower than neurotransmitters, only activate/attach to certain receptors that only certain parts of the body contain, mechanism of action. Larger peptides/proteins: attach to cell wall, trigger response. Steroid hormones: pass through cell membrane since they are also made of lipids, interact in interior of cell. Neurotransmitters: released locally, work quickly (released by action potential, mechanism of action. Master gland sends hormones outward via blood vessels (blood stream) **many of these also stimulate regions in the brain** Anterior pituitary: endocrine gland, not part of the brain: acth, follicle stimulating hormone (fsh) & luteinizing hormone (lh) target: gonads (induce release of testosterone/estradiol/progestin, Trigger hormones created in hypothalamus blood vessels all over hypothalamus enable direct contact with blood stream brings hormones into anterior pituitary stimulates anterior pituitary to release other hormones.
