No Nerve Endings
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
Can demyelinating neuropathy be caused from residual nerve damage even if the nerves are no longer being pinched?
Yes it can: deafferentation pain. Deafferentation refers to the partial or total loss of a sensory nerve supply to a particular body area. Normally, when the sensory supply to an area is compromised, one would expect a decrease in sensation and a loss in ability to perceive pain. However, in some cases involving nerve injury, a paradoxical condition arises. See pain management specialist. ...Read more

Is ilioinguinal nerve the same size as sciatic nerve?Saw mr neurography image of the sciatic nerve.Can ilioinguinal nerve appear that clearly on mrn?
Not likely: The sciatic nerve is anatomically larger than the ilioinguinal nerve. Mrn is not widely available. The ilioinguinal nerve is not as likely to be seen as clearly on mrn as the sciatic nerve. ...Read more
Is nerve testing any less painful if there is a pinched nerve or nerve damage then when the nerves are normal?
Could be yes or no: Sometimes people with nerve damage do not feel pain. Sometimes more electricity is needed to test people with nerve damage, and this can feel painful. Generally, in the 1000s of tests I performed, people with nerve damage found the testing easier. ...Read moreSee 1 more doctor answer
If you have infraorbital neuropathy does that mean you have trigeminal neuralgia, since the infraorbital nerve comes from the trigmeinal nerve?
Possibly: Nerve injury implies some kind of damage to the nerve itself. While spinal cord and nerves are both nervous tissue, nerves typically are structures that have branched outside the spinal cord. Injury to the sciatic nerve, for example, is not considered a spinal cord injury. They are very different structures. ...Read moreSee 1 more doctor answer
Is there a connection between vagus nerve irritation (causing hiccuping) and dementia?
What are causes of vagus nerve irritation?
Not directly: Elderly people may suffer both, but they are not related. Damage to the nerve can result from injuries or even some surgeries. Aging alone can impair it to some degree. Discuss this w/ your doctor so you'll understand better about your condition and what to expect (or not). Best! ...Read more
Here are some ...: Known to you, nerve-endings serve as sentinel to inform brain what may be wrong usually caused by some sorts of chemical or mechanical irritation to local tissues/organs. What is the density of those nerve endings, widely varying to reflect functional need among individuals? Since such a Q serves no practical clinical use so there has been no specific studies or discussion in professional arena. ...Read more
A nerve: The genitofemoral nerve is a single nerve, about the diameter of a piece of spaghetti. It splits into a genital branch and a femoral branch. In males, the genital branch innervates the cremaster muscle and part of the scrotal skin. As with most nerves large enough to have a name, it is composed of a bunch of nerve fibers, also known as axons. ...Read moreSee 1 more doctor answer
