• peripheral nervous system

• central nervous system

• special senses

The parasympathetic division of the nervous system is the

• resting and digesting portion of the system

• peripheral nervous system

• central nervous system

• fight or flight division of the system

Which of the following is TRUE about the sympathetic division of the nervous system?

• It is part of the brain.

• It is part of the central nervous system.

• It is most active in non-stressful situations.

• It is part of the somatic part of the nervous system.

• It is part of the autonomic nervous system.

A nerve cell, the principal cell of the nervous system specialized to transmit messages, is called a

• muscle fiber

• nerve fiber

• neuron

• axon

• dendrite

Which of the following is a neuron that carries information away from the CNS to muscles or glands?
