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

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 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

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

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

Dr. Ki-Hon Lin Dr. Lin
2 doctors agreed:
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

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

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

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

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

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

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 more

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 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?

Spinal anatomy: The lateral recess refers to the side parts of the spinal canal. A focal cyst certainly could be a synovial cyst, which in the spine would arise from the facet joints, the joints at the back part of the vertebra. ...Read more

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 ?

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 more

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?

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

What happens if your spinal cord is crushed or cut?

What happens if your spinal cord is crushed or cut?

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
