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, 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.

Detailed explanation-3: -The epimysium envelops entire muscles. Groups of muscle fibers are arranged in fasciculi that are separated by the perimysium, which is contiguous with the epimysium. The endomysium is a delicate network of connective tissue fibers, blood vessels, lymphatic vessels, and nerves that surrounds individual muscle fibers.

Detailed explanation-4: -Each muscle fiber is surrounded by a thin layer of connective tissue called the endomysium.
