Document Summary

Ability to maintain relatively stable internal conditions. Not unchanging- dynamic state of equilibrium: blood levels, heart activity/blood pressure, managing waste, body temperature. Essential characteristics: receptor- sense changes, sends info, control center- determines set point, analyzes info, determines response, effector- provides means for response. Output reduces stimulus: 1 hormone or neural pathway regulating a process, process regulated in opposite directions by 2 hormones or neural pathways. Enhances original stimulus, change occurs in same direction as original response. Homeostatic imbalance= disturbance of homeostasis (most diseases, associated with aging) System of motor neurons to smooth & cardiac muscle & glands to allow responses usually without our awareness control heart/respiratory rates. Adequate blood flow to each part of the body. Adjust bp and body temp control gastric secretions. Somatic- skeletal muscle, ans- smooth/cardiac muscle, glands (includes blood vessels) Somatic- thick, myelinated axon from spinal cord to skeletal muscles, no ganglia.
