Summary Introduction
To review:
The reason as to why an injury to the spinal cord may impair sensations and motor movement below, but not above the point of injury.
Introduction:
The spinal cord is a complex collection of nerves, which is cylindrical in shape and starts at the base of our brain, running down the vertebral column to the backbone. It is a part of the CNS (central nervous system). The spinal cord serves multiple functions such as maintaining the body reflexes, carrying electrical signals to the brain and back, and providing locomotory functions.
