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: -Blood vessels, the lymphatics and the nerves are all found in the perimysium. Each muscle fibre is surrounded by loose connective tissue, and these contain capillaries and nerve fibres. This connective tissue covering is known as the endomysium (endon-greek for within).
Detailed explanation-3: -Skeletal muscle is surrounded by a layer of connective tissue, which is called the fascia, or epimysium, of the muscle; it consists mainly of collagen fibers.
