ANATOMY

Detailed explanation-1: -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: -Perimysium is a continuous layer of collagenous connective tissue that separates the skeletal muscle tissue into muscle fascicles (i.e., bundles of muscle cells).

Detailed explanation-3: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.

Detailed explanation-4: -The epimysium is a thick connective tissue layer that is composed of coarse collagen fibers in a proteoglycan matrix. The epimysium surrounds the entire muscle and defines its volume.

Detailed explanation-5: -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).
