Assignment:

Perioheral nervous system can be divided into sensory and motor divisions, and the motor division can be also subdivided into autonomic motor system and somatic motor nervous systems. The autonomic nervous system controls involuntary physiologic processes such as heart rate, blood pressure, respiration, and digestion. In contrast, somatic motor nervous system controls voluntary movement of the skeletal muscles and reflex movements.

a. In comparison to the somatic motor nervous system, the autonomic nervous system differently carries out its output signals. Describe output signals in the autonomic nervous system.

b. This nerve fiber pass through the chain without synapsing and continue to a 2"0 set of ganglia and convey visceral efferent and afferent fibers to and from the viscera of the body cavities such as liver, spleen, adrenal glands, and stomach. What is "this nerve fiber"?

c. The autonomic nervous system controls by two different nerve fibers (or divisions. What are the two different nerve filers?

d. Most of the autonomic nerve fibers have antagonistic effects. One example is pupil dilation and constriction. In this case, what neurotransmitters are used for the pupil dilation and constriction?
