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

Common peroneal nerves, f-waves of CPN & PTN, H-reflex, SNAP of sural nerves and superficial peroneal nerves  are not recordable.( report of NCV test)?

NCV Test: A lot of times these NCV tests are inconclusive or need to be repeated. Do you have any symptoms like numbness or tingling? Any history of diabetes or peripheral neuropathy? These disorders may explain those findings. Nerve trauma can also be a possible etiology. ...Read more

Muscle wasting possible due to ulnar nerve compression?

Muscle wasting possible due to ulnar nerve compression?

Yes: Depending on where nerve is compressed, muscles innervated may be affected. Commonly, muscle in first webspace, between thumb and index, become atrophied. Muscles between metacarpals, or interossei, can atrophy. Result is hand weakness with atrophy. ...Read more

Each peripheral nerve provides what innervation to peripheral structures.?

Good question: I wish I could remember. When I have a question about that, I get out my old anatomy book from med school and look it up. The book is 1100 pages long. I refer to it frequently when I want to relearn what peripheral nerve innervates what structure. For laypeople I recommend Frank Netter's Atlas of Human Anatomy. It's available from Amazon. ...Read more

Is surgery needed for foot drop from anterior tarsal tunnel syndrome (deep peroneal nerve entrapment) from ant tib tenosynovitis from ultrasound burn?

Something does not: Sound right about this. The common peroneal nerve can cause a drop foot. The deep peroneal nerve from ant tarsal tunnel is on the top of the foot. The nerve runs deep as the name implies and hence would not be affected from ultrasound. Entrapment of this nerve would not cause a dropfoot, it usually causes numbness to the first webspace or great toe. ...Read more

Is nerve injury the same as nerve damage or spinal cord damage?

Is nerve injury the same as nerve damage or spinal cord damage?

Possibly: Nerve injury implies some kind of damage to the nerve itself.
