What Happens If The Ventral Fiber Of A 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 moreSee 1 more doctor answer
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
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 moreSee 1 more doctor answer
Paraplegia: The ventral roots of spinal cord are involved with motor control of muscles. ...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?
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
Is it possible for a TBI to cause a cyst in the spinal canal of the c-spine? If so, what is the likelihood of it growing? Found after MVA,brain bleed
Yes: yes, car accident causing a whip-lash injury can produce a syrinx (aka cyst) in a cervical spine soon after the MVA, patient may not be symptomatic until months later when it gets bigger but radiographically small cyst can be detected on MRI right away, symptoms include: shoulder/arm pain, loss of feeling to temperature, pain in shoulders/arms ...Read more
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. ...Read moreSee 1 more doctor answer
Can you tell me about nerve root within the lateral recess. there is a mention of a focal cyst, is it the same than a synovial cyst?
Can a person loose muscle mass in the leg from having a compressed nerve in the lumbar spine right at the nerve root and if so is the reversible ?
Yes: Chronic sciatica can cause not only numbess but also weakness and with time atrophy. Unfortunately, sometimes even with surgery to decompress the nerve, the weakness and atrophy may still persist. These type of findings may be a good indication for surgery. ...Read moreSee 2 more doctor answers
Did disectomy for l5/s1 disk herniation with loss of bladder.From nerve conduction doctor told the nerves in leg are regenerating. Is it a good sign?
If you have a pinched nerve in the upper
spine and it causes permanent paralysis, is the paralysis only in the location the nerve attaches to?
Yes: That is correct. The muscles connected to the damaged nerves will not work correctly, or will not work at all. Other nerves that are undamaged will continue to send signals to their muscles, and keep them moving properly. However, muscles work together as groups of muscles. That means weakness or paralysis in a few muscles can make a limb malfunction even if other muscles in the limb are working. ...Read more
Is it likely to have an excessive bone growth on a vertabrae that hits the sciatic nerve instead of a bulging or herniated disc?
No: But it's not impossible.Get a more detailed answer ›
Bad Prognosis: If spinal cord is severed, all functions inferior will be essentially ablated, and paralysis, sensory perception loss, and bowel/ bladder function will be destroyed. A crush is more variable with maybe some preservation of function, but could be as severe as through and through cut. ...Read more
