What Happens If The Ventral Root Of A Spinal Nerve Were Cut
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 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
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
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
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
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
Paraplegia: The ventral roots of spinal cord are involved with motor control of muscles. ...Read more
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. ...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.
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

A homework question?: You're 34 so I'm guessing it's not a homework question. I just did a web search using your question & got a great profusion of hits. Don't take offense, but HealthTap docs do this to apply medical reasoning to posters' questions, not so they can regurgitate facts that anyone, physician or nonphysician, can look up for themselves. ...Read more
Difficult to repair.: You don't state which drugs in particular caused the damage, or what the nature of the damage is. So because the question is so general, so must be the answer. In general nerve tissue does not regenerate or repair itself, except for limited nerve plasticity, mostly in children younger patients and there is no known medical intervention. If your issue is opiates, please see www.Opiatecure.Com. ...Read more
You can't: "repair" it by anything you do. Some people might advise making sure you have adequate b vitamins, particularly thiamine, which is necessary for good nerve function, so you might take a therapeutic multivit, but I am unaware of any studies that would indicate they work. Nerves may heal over time. If the nerve was actually physically damaged, you could see a neurosurgeon for advice. Stop using. ...Read more
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
YES: Damage to the nerves that supply the perineum may result in penile numbness. It is well known that bicycle riding, which is an excellent aerobic exercise, may result in penile numbness. This may result from nerve damage or vascular compression resulting arterial insuffiency, swelling and even blood clots. If you're having numbness your pcp may refer you to a urologist & neurolidt for evaluation. ...Read more
When there is damage to the spinal nerve, why can't doctors reattach it like reattaching hands for inst ens?
Change over time: Sometimes nerves can be reattached. It depends how long they have been injured. There are elements within nerves that are very small, these must be maintained for nerves to work in their normal fashion. They cannot be repaired surgically when they have been injured for a long time because they change on the inside after the injury. ...Read more
If I have spinal nerve damage from an lp, how will i know for sure? Will an MRI show that type of damage?
Nerve damage: Spinal access may cause nerve damage, espeically in untrained hands. An emg/ncv (electro-myogram, nerve conduction velocity) study would reveal if there is actual nerve damage. The damage may also depend on the type of needle used to access the spinal fluid. A sharp needle may lead to more damage compared to a "pencil-point" needle. ...Read more
Can a spinal nerve compression & hip injury cause urinary problems such as frequency, cystitis feeling wanting to go double voiding in the morning?
Yes: This may be just temporary. Cord compression injuries can lead to partial urinary retention therefore making it more difficult to urinate and having to double void. Hip injuries are often painful and require narcotic pain medication which also can lead to partial urinary retention. Work on a good bowel program having daily bowel movements, this will help as you seek additional care. ...Read more
Every now and then i get this pain in my hips and my lower back both my parents think that I have a pinched spinal nerve it hurts when i breath deeply?
Doubtful: Though young patients may not have classic sciatica, or shooting pain in the leg past the knee from nerve pressure, your symptoms are not characteristic. Inspiratory pain suggests to me an intercostal or oblique muscle strain/tear. Back to hip pain could indicate a stress fracture (based on your age) that would be worse with leaning backward. "every now and then" isn't too worrisome. ...Read more
