Document Summary

Consists of motor neurons that: innervate smooth and cardiac muscle and glands, make adjustments to ensure optimal support for body activities, operate via subconscious control, have viscera as most of their effectors. Can be broken down into sympathetic and parasympathetic divisions. The ans differs in the following ways: effectors. The effectors of the sns are skeletal muscles. The effectors of the ans are cardiac muscle, smooth muscle, and glands. Heavily myelinated axons of the somatic motor neurons extend from the. Axons of the ans are a two-neuron chain. The preganglionic (first) neuron has a lightly myelinated axon. The ganglionic (second) neuron extends to an effector organ. The sympathetic mobilizes the body during extreme situations. 2 involves e activities exercise, excitement, emergency, and embarrassment. 3 promotes adjustments during exercise blood flow to organs is reduced, flow to muscles is increased. 4 its activity is illustrated by a person who is threatened. 4. 1 heart rate increases and breathing is rapid and deep.
