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

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

Weakness or paralysi: The ventral root contains the motor fibers which control our muscles. Because muscles have multiple nerve roots innervating them the result may only be weakness in a particular group of muscles or could be paralysis if the particular nerve root is the dominant root. ...Read more

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

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

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

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. ...Read more

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

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

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. ...Read more

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

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

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.". ...Read more

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

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

It may create: 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. ...Read more

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

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

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. ...Read more

Explain to me why Paget disease could cause abnormal pressure on a spinal nerve?

Thickened bone: In paget's disease, the bones break down, then try to rebuild themselves. The problem is, the new bone formation is abnormal - the bone is laid down haphazardly and is weaker and thicker than normal bone. If this happens in your vertebrae, the thickened bone can put pressure on the spinal nerves. ...Read more

What specific imaging test takes pics of the nerves coming out of (exiting) the spinal cord? I believe their called spinal nerve roots, not sure.

What specific imaging test takes pics of the nerves coming out of (exiting) the spinal cord? I believe their called spinal nerve roots, not sure.

MRI (best) or CT: An MRI of the spine is the most accurate imaging test to evaluate the spinal cord and the nerve roots exiting the spinal canal. This is most often done without an injection of contrast, however there may be an indication for you to receive an injection of contrast with the MRI. As a Neuroradiologist I often discuss with and advise the referring physician regarding the need for contrast. ...Read more

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

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

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. ...Read more
