Chapter 12.1, Problem 1LO

Summary Introduction

To describe: How the spinal cord can function without input from the brain.

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 brainstem and extends toward the lumbar region of the vertebral column. It consists of 31 segments and 31 pairs of spinal nerves.
