MICROANATOMY

Detailed explanation-1: -The outermost connective tissue sheath surrounding the entire muscle is known as epimysium. The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium.

Detailed explanation-2: -The endomysium is a delicate network of connective tissue, which surrounds individual muscle fibres and contains the vessels and nerves that supply the muscle fibres as well as the proteoglycan matrix for ion flux and metabolic exchange.

Detailed explanation-3: -This connective tissue covering is known as the endomysium (endon-greek for within). The collagen fibres of these connective tissue wrappings merge with the tendons, aponeuroses, or periosteum-the dense connective tissue structures that link the muscle to bone, on which the muscle pulls.

Detailed explanation-4: -The endomysium is the connective tissue that surrounds each muscle fiber (cell). The perimysium encircles a group of muscle fibers, forming a fascicle. The epimysium encircles all the fascicles to form a complete muscle.
