MUSCLE PHYSIOLOGY

Detailed explanation-1: -The outermost sheath of connective tissue covering each muscle is called epimysium.

Detailed explanation-2: -The plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma is the site of action potential conduction, which triggers muscle contraction. Within each muscle fiber are myofibrils-long cylindrical structures that lie parallel to the muscle fiber.

Detailed explanation-3: -The sarcolemma is a specialized cell membrane which surrounds striated muscle fiber cells. Sometimes called the myolemma, the sarcolemma is similar to a typical plasma membrane but has specialized functions for the muscle cell.

Detailed explanation-4: -The plasma membrane and ER of striated muscles are called sarcolemma and sarcoplasmic reticulum. respectively.
