Question 1

can you tell me the function of the dorsal root of the spinal nerve?

Accepted Answer

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.

Question 2

what happens if the dorsal root of a spinal nerve is damaged?

Accepted Answer

Pain, burning: The dorsal root ganglion is a very sensitive part of the nerve origin and may be damaged.  It results in severe pain, burning, tingling, numbness, and weird sensations such as a feeling of bugs crawling upon the extremities (called paresthesias).

Question 3

what will happen if an injury cuts the dorsal root of a spinal nerve that carries feelings of pain?

Accepted Answer

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.".

Question 4

what would happen if there was a destruction of the spinal nerve's dorsal root ganglion?

Accepted Answer

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.

Question 5

what happens if the ventral root of the spinal nerve is cut?

Accepted Answer

Loss of motor contro: Loss of motor function with sensory preserved.Ventral branch has efferent motor dorsal has afferent sensory.

Question 6

what do swellings on the dorsal roots of the spinal nerves signify?

Accepted Answer

Irritation: If the nerve roots are under pressure from a disc herniation or tightness from the spinal canal itself ( i.E stenosis), the nerve roots will be compressed and they become inflamed and swelling occurs. This is painful and the treatment can be exercises, injections and ultimatley surgery to relieve pressure if non surgical methods to not work.

Question 7

what is the inflammation of the root of a spinal nerve?

Accepted Answer

see below: A spinal nerve (root) is a large nerve bundle that leaves the  spine at regular intervals, right and left. Inflammation can occur anywhere in the body. Think of a bee sting, with pain, swelling and sensitivity. Inflammation of the nerve root, causes pain close to the spine, and along the route of the nerve. Epidural steroid injections are sometimes used to place anti-inflammatories into the spine.

Question 8

what does it mean to have inflammation of the root of a spinal nerve?

Accepted Answer

Problem xitng spine: Nerves branch off in bundles from the spinal cord & exit thru an opening between the vertebrae.This is the nerve root. The opening itself is subject to narrowing or irritation from arthritis or various illnesses as are the tissues nearby. Nerve bundles are surrounded bu flexable tissue that can be compressed by the swelling nearby and end up choking off some of the nerve activity.

Question 9

if ventral root of a spinal nerve were cut what will be the result in the tissure?

Accepted Answer

motor loss: The ventral root of the spinal nerve carries the motor fibers, where the dorsal root carries the sensory fibers.  So if the ventral root of a nerve was cut, a motor loss would occur; i.e. Either severe weakness or paralysis in the involved muscle.  Thank you.

Question 10

if the ventral root of a spinal nerve were cut, what would be the result in the tissue or region that nerve supplies?

Accepted Answer

Atrophy or wasting.: When a muscle is denervated, it atrophies or 'shrivels up'. This is why patients who had polio have small paralyzed limbs in the effected distribution.
