In order for a severed peripheral nerve to regenerate and recover its original function, nerve fibers must sprout and enter tubes formed by the common sheath of Schwann cells, called the bands of Büngner. These structures provide a supportive environment for axonal growth and guidance during the regeneration process.

What is loss If the anterior root of a spinal nerve is severed?

The anterior or ventral roots carry motor or efferent information from motoneurons in the anterior horn to muscles. This is as opposed to the dorsal roots that convey sensory or afferent informaiton from the periphery to the dorsal horns of the spinal cord. This is not to be confused with ventral rami that subserve intrinsic muscles of the back and neck. Therefore if a ventral root is severed or cut there would be a loss on motor function to muscles in the distribution of that root (called a myotome).
