Question
Chapter 16, Problem 3CR
Summary Introduction
To determine:
The name, composition, and the type of nuclei present in the three gray matter horns on each side of the spinal cord.
Introduction:
The gray matter is located in the center of the spinal cord. It is surrounded by the white matter. The gray matter contains neuron cell bodies with a myelin sheath. It is considered as the site for information processing and synaptic integration.
