Summarize the differences between the somatic motor division and the autonomic nervous system
What will be an ideal response?
The somatic motor division consists of neurons that transmit signals to skeletal muscles. Skeletal muscle tissue is under voluntary control, so this division is sometimes called the voluntary motor division. By contrast, the autonomic nervous system consists of neurons that carry signals primarily to the thoracic and abdominal viscera. The ANS regulates secretions from certain glands and contractions of both smooth and cardiac muscle tissue. The ANS is sometimes called the involuntary motor division since it controls functions that are generally under involuntary control.
