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 lining over muscle fibre is called sarcolemma. The protoplasm in the muscle fibre is called sarcoplasm. The endoplasmic reticulum in muscle fibre is called sarcoplasmic reticulum.
Detailed explanation-5: -structure of striated muscle …a muscle cell, called the sarcolemma, separates the sarcoplasm (muscle cell cytoplasm) from the extracellular surroundings. Within the sarcoplasm of each individual muscle fibre are approximately 1, 000 to 2, 000 myofibrils.
