41
Describe and tell function of gray matter.
* A central, butterfly-shaped area composed of masses of short nerve fibers. * This is the part of the spinal cord that receives in-coming nerve impulses from the body.
42
Describe and tell the function of white matter.
* Masses of long fibers that lie outside the gray matter and is white because if the myelin sheath surrounding the long fibers. * This is the part of the spinal cord that sends nerve impulses to the brain & recovers them from the brain.
