Document Summary
Physiology: study of how living organisms function, how anatomical structure is suited for function, how different parts have integrated functions, physiology - study of healthy organisms, we will occasionally look at disease states (pathophysiology) Anatomy of a negative feedback loop production on: stimulus (change to internal environment) sensor (change is detected by receptor/sensor) control center (change is compared to set point - ex: brain) . Effector (muscles or glands) change is corrected. Biochemistry of negative feedback: negative feedback systems are often used to control production, secretion, or activation of a chemical product (ex: testosterone) Feedback system control center: all homeostatic mechanisms involve coordination and communication, nervous system or via secreted chemicals. Andes mountain natives: control s sleep-wake cycle, body temp, hormone concentrations in blood, excretion of ions in urine, and others, 24 hour clock, anatomy involved: hypothalamus, pineal gland (secretes melatonin) targets of. Influenced by: light, external temp, meal timing, social cues.
