Chapter 13.3, Problem 1QC
Summary Introduction

To review:

The structures that form the spinal nerve and the reasons behind all spinal nerves being mixed.

Introduction:

The spinal nerves generate from the spinal cord and extend up to the neck and head. They contain a bundle of nerves that connects exterior and interior parts of the body. The total number of spinal nerves is 31 and they contain both motor neurons and sensory neurons. The spinal nerve contains fascicles, endoneurium, myelinated axon, and unmyelinated axon of the neurons.

Blurred answer
Students have asked these similar questions
Which structures form a spinal nerve? Why are all spinal nerves mixed?
Which structures unite to form a spinal nerve?
Is a spinal nerve composed of axons from afferent or efferentneurons, or both?
