Explanation The spinal nerves branch into dorsal ramus, ventral ramus, meninges, and rami communicants. The rami contain both motor and sensory fibers. The dorsal ramus is posterior to the ventral ramus (anterior) and serves the skin and muscles of the posterior body trunk. It is usually smaller than the ventral ramus...

Chapter 7, Problem 29SAE

Summary Introduction

To review:

The regions of the body that are served by the dorsal rami of the spinal nerves along with the ventral ramus.

Introduction:

The spinal nerves are the mixed nerves that arise from the spinal cord, unlike the cranial nerves that arise from the brain. The spinal nerves act as a connection between the body and the spinal cord. Each of the spinal nerve has two roots, dorsal root and the ventral root.
