Question
Chapter 7, Problem 3RA
Summary Introduction
To determine:
The pseudounipolar neuron.
Introduction:
The nervous system controls and coordinates all other systems of the body. The nervous system can be classified into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is comprised of the brain and the spinal cord whereas, the PNS is constituted of the cranial nerves and the spinal nerves. The peripheral nervous system controls involuntary actions of the body.
