What is dorsal ramus of the spinal nerve?

What is dorsal ramus of the spinal nerve?

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

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

Posterior left disc herniation 6.3x10.5mm impinging on the left s1 nerve root also a degree of narrowing of the left neural foramen impinging L5 nerve?

Posterior left disc herniation 6.3x10.5mm impinging on the left s1 nerve root also a degree of narrowing of the left neural foramen impinging L5 nerve?

Disc protrusion: The L5-S1 disc is very susceptible to protrusion since it gets more load than most other lumbar discs. The disc is impinging on the nerve roots as they exits the spinal canal. Your neurologist might suggest conservative approaches like muscle strengthening exercises & physical therapy to help address your pain. http://www.nlm.nih.gov/medlineplus/herniateddisk.html ...Read more

What is facet hypertrophy l Flatten the ventral thecal sac and encroach upon the lateral recesses abutment of the traversing nerve roots?

What is facet hypertrophy l
Flatten the ventral thecal sac and encroach upon the lateral recesses abutment of the traversing nerve roots?

Pain and weakness: can result from compression of the nerves that exit at the level of the narrowing caused by bony overgrowth of the facets (the area where the vertebral bones meet) In the lumbar region the nerves exit at a higher level and "traverse" the space next to the facets below this before they exit the spinal canal at a lower level. Discuss this with your doctor. ...Read more

My MRI report say this: levoconvex curvature of the lumbar spine. The spinal cord terminates at the inferior aspect of the t12 vertebral body.Meaning?

My MRI report say this: levoconvex curvature of the lumbar spine. The spinal cord terminates at the inferior aspect of the t12 vertebral body.Meaning?

Doctor speak: We need to sound smart. It basically means a bit of a scoliosis i the lower spine with the apex of the curve pointed to the left. The spinal cord is ending at the bottom of the last thoracic vertebrae, which isn't to far from normal. Speak to your doctor and they can likely go over the actual films with you and show you what they mean. ...Read more

MRI of my Cervical Spine There is disc degenerative changes with associated impingement of the thecal sac , exit neuroforaminal encroachment.



MRI of my Cervical Spine 
There is disc degenerative changes with associated impingement of the thecal sac , exit neuroforaminal encroachment.

MRI result?: So- what does this mean? It is common for MRI of the c-spine to show degenerative changes. Impingement of the thecal sac is not normally concerning. It is unclear what is meant by "exit neuroforaminal encroachment". Was there encroachment or not? If it is there, this normally means nerve root encroachment, which can cause symptoms that affect the arms. ...Read more

In WHIPLASH INJURY the nerves originating from spine inside vertebral column, CAN NERVES SNAP OUT? Due to rapid movement of neck.

In WHIPLASH INJURY the nerves originating from spine inside vertebral column, CAN NERVES SNAP OUT?  Due to rapid movement of neck.

No: Short of a traumatic displaced fracture or dislocation of the spine, the nerves do not "snap out" of their normal position. They are protected by strong ligaments and the bone architecture of the vertebral column that would have to be disrupted for them to move into an abnormal position. ...Read more

Could a dilated batson's plexus compress against nerves in the lumbar spine?

Could a dilated batson's plexus compress against nerves in the lumbar spine?

Unlikely: Batson's plexus is the name for the veins that surround the vertebral bodies. Veins are very compressible so they are unlikely to cause any pressure on nerves. ...Read more

Could a dilated batson's plexus compress against nerves in the lumbar spine?

Not typically: The batson's plexus significance is that it's a network of veins without valves. Typically veins have valves, due to the low pressure in the venous system, to decrease the chance of flow backup within the system. The batson's plexus connects the deep pelvic veins & thoracic veins, & with no valves can easily serve as conduit for infection/cancer cells to travel from pelvic structures to the spine. ...Read more

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

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

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 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

One of my spinal chords in my lower back is dislocated and is pushing on my nerves, causing me a lot of pain, is a disk surgery recommended?

No: Your vertebrae are likely not dislocated as this is a result of high-energy trauma and requires surgery for reduction and stabilization. You likely have bulging discs, which is normal in 15% of the population of your age. Physical therapy will likely help you and maybe steroid injections if pt doesn't work. Hold off on surgery, it's always the last resort and you're very young. ...Read more

I'm getting surgery on my lower back.One of my spinal discs is trapping a nerve. What should I expect?

Hopefully relief: If your leg pain is the main problem and you have failed nonop care and are not a smoker, your success rate should be at least 90%. Postop rehab in terms of guided exercise and back specific education is important to minimize risk of recurrence which is about 5% and further development of back pain in the 10% range. This is assuming you are having a disc surgery without any fusion ...Read more

Pinched nerve in spinal core lower back leads to from foot or sitting constantly?

Pinched nerve in spinal core lower back leads to from foot or sitting constantly?

Pinched nerve: Not sure what is being asked here but sitting constantly is not typically a cause of pinched nerves. At your age, a pinched nerve would be more typically caused by disc degeneration (aging changes) leading to susceptibility of the disc to protrude/herniate, which results in nerve impingement (pinched nerve). ...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

Would spinal tumor show up on xray.Nearly constant back pain.Doc doesnt seem concerned.Say's it's just impinged nerve. Xray show compressed low spine?

Would spinal tumor show up on xray.Nearly constant back pain.Doc doesnt seem concerned.Say's it's just impinged nerve. Xray show compressed low spine?

Often yes: The most common tumors in the spine are cancers that have metastasized from other primary sites. They can appear as either dense (blastic) or clear (lytic) lesions on the X-Ray. In rare cases, nerve, bone marrow or, bony tumors can arise in the spine itself. At age 22, other musculoskeletal problems are far more common as cause of low back pain. ...Read more
