ANATOMY

Detailed explanation-1: -Each muscle is made up of groups of muscle fibers called fascicles surrounded by a connective tissue layer called perimysium. Multiple units of individual muscle fibers within each fascicle are surrounded by endomysium, a connective tissue sheath.

Detailed explanation-2: -Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.

Detailed explanation-3: -The whole muscle is enclosed by a dense connective tissue sheath called the epimysium. (Epi-greek for upon, mys-greek for muscle). The muscle fibres are divided up into bundles of fibres called ‘fascicles’. Fibrous sheaths that surround the fascicles are called the perimysium (peri is greek for around).

Detailed explanation-4: -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-5: -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.
