Document Summary

Nervous: deviations from set point stimulates a receptor which sends info to control center (brain); brain directs an effector (muscle/glands) to induce an adaptive response & regain homeostasis. Endocrine: chemical info transferred via hormones to regulate tissues: negative feedback thermoregulation: Receptors: peripheral nerve receptors in skin & blood-temp monitors near hypo. Changes in ventilation can also be used (to reduce co2 build-up: case study hyperthermia: Increase in body temp without increase in set point of thermoregulatory center in hypo. Includes heat exhaustion (thirst, fatigue, sweating, delirium; slightly elevated temp w/ loss of water & electrolytes) and heat stroke (high temp, no sweating, unconscious; often fatal) : beta cells of pancreas; regulates carb and fat metabolism; increases glucose transporters on cells = increase in uptake; assembled as hexamer, active form is a monomer; contains histidine & zinc. Diabetes 1 vs 2: can"t produce insulin vs. not enough/resistance to it.
