What occurs when the median nerve is compressed as it passes through the narrow area in the wrist?

Carpal tunnel : syndrome is the medical name for that but I'm sure you know that If you mean what exactly happens Most studies talk about a change in the blood flow to the nerve initially the epineurial l tissue Later a change in this layer leads to more consistent nerve problems which is reflected as an alteration in the nerve conduction velocity. Has these nerve changes accelerate clinical symptoms progress as well ...Read more

Which nerve from the spine innervates the colon?

Which nerve from the spine innervates the colon?

You asked for it: Sympathetic fibers from the spinal cord lead to the celiac ganglion (foregut) and superior (midgut) and inferior (hindgut) mesenteric ganglia. Parasympathetic fibers arise from the vagus (innervate the foregut and midgut (through transverse colon)) and the hindgut (pelvic nerves which innervate the descending colon, sigmoid, and rectum). Does that answer your question? ...Read more

What is effacement of the right exiting nerve root?

Being pressed on: This means the nerve root is being pressed on as it exits the spine. For example, it could be pressed on by a disc or by changes in the bones or ligaments related to arthritis.
