Question

Quizplus · Accepted Answer

The thin layer of cells found wrapped around nerve cell fibers outside the brain and spinal cord is called the neurilemma. Its primary function is to aid in the repair of damaged neurons. Myelin, on the other hand, is a fatty material that forms a protective insulation around nerve fibers. Acetylcholine and endorphins are neurotransmitters that play a role in nerve cell communication and are not directly involved in repairing neurons.
