Explanation The major peripheral branches of the spinal cord are the posterior ramus, anterior ramus, and rami communicantes (white ramus communicans and gray ramus communicans). Posterior ramus: The posterior ramus consists of mixed nerves that provide sensory and motor innervation to the skin and skeletal muscle of the back. Anterior ramus: The anterior ramus carries the sensory information from the ventrolateral body surface and structures of the body wall of the limbs to the spinal cord...

Summary Introduction

To describe: The rami associated with spinal nerves.

Introduction: The spinal cord and the brain make up the major part of the central nervous system. The spinal cord is a tube-like structure that begins from the medulla oblongata of the brain stem and extends toward the lumbar region of the vertebral column. It is covered by three protective layer or meninges, namely, the dura mater, arachnoid mater, and pia mater.
