Lets you feel things


The nerve root has 2 "ganglions". The dorsal root is on the posterior side of the nerve (closer to your back) and carries the fibers that allow you to feel things in your extremities (for example: pain, temperature, vibration). The information is transmitted to your brain so you understand what type of sensation is being encountered by the extremity.

neuropathic pain as this is in the vicinity of the dorsal root ganglion and may affect that nerve's functional distribution as well depending on what type of overlap or cross innervation that may be in that individual.

Loss of sensation


Destruction of the dorsal root ganglion would interrupt the sensory pathway of that particular nerve - therefore, one would be expected to have numbness in the distribution of that spinal nerve.

Numbness


The dorsal (posterior, toward the back) root carries sensation nerve fibers: feeling of light touch, vibration, sense of position (movement or where the arm or leg or joint is), pain. However, there is much overlap between the area serves by a single nerve, so there may not be total loss of sensation, depending on how the person is "wired."

In what way are nerves in the spinal cord damaged?

Answered by:
Dr. Robert Kent
Physical Medicine and Rehabilitation

Most often trauma


Trauma can either sever the nerves or cause enough inflammation and swelling that a section can die off, with same results. Other things, such autoimmune, ischemia (lack of blood flow) and infection, can severely damage the cord as well.
