Heidi's posterior horn of spinal gray matter is the part of the spinal cord that must have been injured due to a car accident.
<h3>What is a Spinal cord?</h3>
A spinal cord may be defined as a portion of the central nervous system that sprints from the underside of the skull down to the epicenter of the back.
The posterior horn of the spinal gray matter involves the function of receiving sensory information from the body. Such as vibrations, adequate touch, proprioception, etc.
Thus, when a person loses the ability of sensation in her arm or any part of the body, it indicates that the posterior horn of the gray matter is functionally adversely.
Therefore, it is well described above.
