ANATOMY

Detailed explanation-1: -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-2: -Muscle connective tissue is found at three levels of scale: the epimysium, which surrounds the muscle; the perimysium, which surrounds bundles of muscle fibers; and the endomysium, which surrounds muscle fibers.

Detailed explanation-3: -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-4: -Fibrous sheaths that surround the fascicles are called the perimysium (peri is greek for around). 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.

Detailed explanation-5: -Fascicles within the muscle are enveloped by a sheath called theperimysium. Single muscle fibers within individual fascicles are surrounded by a sheath called theendomysium.
