MEDICAL PHYSIOLOGY

Detailed explanation-1: -Sarcolemma. Sarcolemma is the name of the cell membrane that encloses each muscle cell, specifically muscle cells ("muscle cell” = “muscle fibre") Epimysium-thick layer of collagenous connective tissue that separates large bundles of muscle.

Detailed explanation-2: -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-3: -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-4: -Each muscle fibre is lined by the plasma membrane called sarcolemma enclosing the sarcoplasm. Muscle fibre is a syncitium as the sarcoplasm contains many nuclei. The endoplasmic reticulum, i.e., sarcoplasmic reticulum of the muscle fibres is the store house of calcium ions.
