Document Summary

Sensorimotor cortex and basal ganglia both work closely with the cortex, communicating to each other. Spinal cord from which motor neurons exit to go to muscles. Basal control, reflex works even when unconscious. Tensions in muscles and tendons, angles of joints send back info to cns. Autonomic or unconscious involuntary response of effector organs to a stimuli. Always the same response to the same stimuli. Sensory cells (receptor), sensory nerve fibres, coordinating centre (cns), motor nerve fibres, effectors (muscles and glands) Malfunction of any one of the components lead to the alteration in the response. Muscle spindle and tendon for stretch and tension. The stimuli will induce ion leakage (such as stretching or bind to chemicals) to initiate ap. Frequency coding: frequency of ap proportional to intensity of energy transduced, enables cns to detect intensity. There is always some basic ap going on, a stimulus causes a burst of ap.
