ANATOMY

Detailed explanation-1: -Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Detailed explanation-2: -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-3: -The epimysium is the dense connective tissue that surrounds the entire muscle tissue. The epimysium usually contains many bundles (fascicles) of muscle fibers.

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, meaning within the muscle, is a wispy layer of areolar connective tissue that ensheaths each individual muscle fiber, or muscle cell. It also contains capillaries and nerves.
