Document Summary

Directly into blood act as receptors (on other endocrine glands) Notes: metabolism (diabetes, reproduction (cancers & infertility, fluid & electrolyte balance, growth. Differentiate between direct and indirect response (give examples of hormones). Direct: hormone binds receptor effect you can see. Indirect: involves downstream hormone (trophic effect) affects endocrine. T or f: negative feedback may be exerted from non- hormonal signals. Give an example of normal feed(cid:271)a(cid:272)k (cid:449)he(cid:374) : t h, T or f: pituitary is not part of the brain. Thyroxine: inhibits thyroid stimulating hormone (tsh) and trh. T h / t(cid:1008) (compensation causes hyperthyroidism) T h / t(cid:1008) (compensation causes hypothyroidism) Primary: feedback is normal; problem resides in tissue. Negative: abnormal feedback; problem resides in endocrine signalling system. T h / t(cid:1008) (why is tsh not elevating?) T h / t(cid:1008) (cid:894)(cid:449)h(cid:455) is(cid:374)"t t h (cid:271)ei(cid:374)g (cid:374)eg. feed(cid:271)a(cid:272)k? (cid:895) Too much: often involves a tumor; may be ectopic.
