Quizplus · Accepted Answer

Areas of the brain containing mainly myelinated axons are commonly referred to as white matter, due to the white appearance of myelin sheaths. Gray matter, on the other hand, contains mainly cell bodies and unmyelinated axons. Neurilemma refers to the protective sheath around peripheral nerve fibers, and reflex arcs refer to neural pathways that control reflexive responses.
