MUSCLE PHYSIOLOGY

Detailed explanation-1: -What is the sarcolemma? It is the thin, transparent, extensible plasma membrane of the muscle cell. It consists of a cell membrane (plasma membrane) and an outer coat made up of a thin layer of polysaccharide (glycocalyx) material with numerous thin collagen fibrils.

Detailed explanation-2: -The sarcolemma maintains the intracellular milieu, actively transports substrates into the muscle cell, serves as a docking location for proteins originating in the basement membrane and cytoskeleton, and also transmits neural excitatory impulses that lead to muscle contraction.
