ANATOMY

Detailed explanation-1: -The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue. The sarcolemma is an excitable membrane and shares many properties with the neuronal cell membrane.

Detailed explanation-2: -The muscle cell membrane is called the sarcolemma and the cytoplasm, the sarcoplasm. The sarcolemma has the property of excitability and can conduct the electrical impulses that occur during depolarization.

Detailed explanation-3: -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.

Detailed explanation-4: -The sarcolemma is the plasma membrane. The sarcolemma is described as having two layers. The first is the plasma membrane, which is a structure of similar biochemical composition to the general plasma membrane found in eukaryotic cells. The second layer is the glycocalyx, which is in contact with the basement membrane.

Detailed explanation-5: -Sometimes called the myolemma, the sarcolemma is similar to a typical plasma membrane but has specialized functions for the muscle cell. The sarcolemma also contains an extracellular matrix consisting of various polysaccharides which allows the cell to anchor into the tissues that build and support muscle fibers.
