AMY-2A Lecture Notes - Lecture 2: Adrenal Medulla, Pineal Gland, Circadian Rhythm
Document Summary
Prl: prolactin, lactogenic hormone, stimulates mammary glands to produce milk, released due to high levels of estrogen. Low bp, low na in blood angiotensinogen (kidneys) angiotensin i angiotensin ii (lungs) increases bp. Puberty/sex cell production gnrh (hypothalamus) fsh and. Lh/icsh (anterior pituitary) stimulation of follicles/gametes in gonads. Ct (thyroid): decreases blood calcium, stimulates osteoblasts. Pth (parathyroid): increases blood calcium, stimulates osteoclasts, activates active vitamin d (calcitriol) E/ne (adrenal medulla): sympathetic, fight or flight response, vasoconstriction, dilation in bronchioles, decreases digestive and urinary output. Aldosterone (adrenal cortex)- deals with the conversation of sodium in the body, increase blood pressure. Due to: high potassium, low sodium, low blood pressure, low chloride, also acth causes the release of this, renin, angiotensin i, angiotensin ii. Adh/vasopressin (neurohypophysis)- deals with the conservation of water in the body, increase blood pressure. Due to: high potassium, low sodium, low blood pressure, low chloride. Anp (atrium of the heart)- deals with the excretion of sodium, decrease blood pressure.
