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

How many genito femoral nerves innervate the cremaster muscle?A single nerve or multiple?

How many genito femoral nerves innervate the cremaster muscle?A single nerve or multiple?

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 more

Can a hernia affect the posterior femoral cutaneous nerve ?

Can a hernia affect the posterior femoral cutaneous nerve ?

Hernias can do a lot: The "posterior cutaneous nerve" I think is AKA posterior division of the lateral femoral cutaneous nerve (LFCN). LFCN problems mess up feeling in the front, outside of the thigh. Symptoms usu. happen with seat belt inj., bone grafts and diabetes. There are many weird hernias in the pelvis so it seems possible to compromise the LFCN but in 30 yrs of reading CT and MRI, I've not seen it. ...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. 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 more

Piriformis trapped nerve dangerous?

Piriformis trapped nerve dangerous?

Piriformis sciatica: I'm not sure what you mean by "dangerous". Most cases of piriformis syndrome with intermittent sciatica are painful, but not at all what i'd consider dangerous. As you can see from the image attached, the sciatic nerve can pass behind the muscle or split the muscle (just butt pain then), or one or both parts of the nerve can pierce the muscle which can cause the shooting pain down the leg. ...Read more

Can vitamin B12 deficiency cause Musculocutaneous nerve and ILiohypogastric nerve damage ?

Causes neuropathy: But unusual to have an isolated mononeuropathy over arm and abdomen. If indeed this pattern of isolated nerve involvement fits a mono neuritis multiplex, one would wonder about another responsible disorder such as diabetes or arteritis. Vit B-12 problems are typically symmetrical and distal. Might investigate all of this further with your neurologist. ...Read more
