Chapter 6, Problem 7CR

Summary Introduction

To review:

The rationale behind paralysis of skeletal muscles of the limb by spinal cord injury to the neck, while no effect of the injury to the cardiac muscles is not affected as the heart beats rhythmically.

Introduction:

Spinal cord injuries are irreparable as the nerve cells do not have the ability to regenerate. When there is a minor injury to the spinal cord at the neck region, the damage to the body could be manageable, but if the damage is extensive then all the limbs below neck region are paralyzed. In both cases, the cardiac muscles are not affected.
