Document Summary
Characteristics of hormones: control: synthesis and release are controlled by tissues/organs (i. e. hypothalamus-pituitary axis) Patterns of secretion, metabolism, elimination: receptor binding: must locate and attach to target, action: effects on target cells, tissues, organs. Control mechanisms (* memorize hormone name and function) Note: ovarian hyperstimulus syndrome: when doctors use the fertility drugs used to stimulate your ovaries, you will to produce more eggs in order to increase the fertility possibility. However, this clinical action might interrupt and impair the negative feedback mechanism. The over stimulating of ovaries will cause the enlargement, inflammation of ovaries; altered fluid balance and possible organ failure. Intervention: need to monitor blood work (especially lh/fsh level) regularly. Positive feedback loop example (oxytocin during labor and delivery) ----positive feedback is usually specific, less common. If positive feedback loop interrupted, might cause the difficulty deliver birth (it"s a very dangerous situation). Ans: fight or flight , sympathetic ( hr, bp, rr, pupil dilation, sweating)
