Document Summary
Cytokines - regulate other immune system cells. Neurotrophins - paracrine regulators of nervous system. Prostaglandins - 20-carbon-long fatty acid w/ carbon ring. Cause constrictions/dilations of blood vessels inhibits gastric secretions. Nonsteroidal anti-inflammatory drugs (nsaids) - drugs that inhibit inread invented by teads production of prostaglandins. Can also inhibit enzyme that maintains walls of digestive tract posterior pituitary gland - fibrous part of pituitary gland, derived from brain. Directly controlled by hypothalamus through the supraopticohypophyseal tract. Consists of axons (cell bodies in hypothalamus) Antidiuretic hormone (adh) - aka vasopressin frequent urination occurs if kidneys don"t retain water. Alcohol suppresses adh >> more urination to rid body of toxins. Oxytocin - stimulates uterus contractions and mammary glands (milk- letdown reflex) in women. Neuroendocrine reflex - involves both the neural/endocrine systems anterior pituitary gland - glandular part of pituitary gland, not derived from brain. Releases mostly growth hormones (aka tropic hormones, tropins) Gonadotropin - hormone that stimulates other reproductive hormones includes fsh, lh.
