MICROANATOMY

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: -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-3: -Each fascicle is wrapped in connective tissue: the perimysium. The process is repeated within the fascicle, with each muscle fibre surrounded by an endomysium.

Detailed explanation-4: -Note: The perimysium is the loose connective tissue that surrounds each bundle of muscle fibers. The endomysium is a fine and delicate layer of areolar connective tissue that encases each muscle fiber. It also contains capillaries, nerves, and lymphatics.

Detailed explanation-5: -A connective tissue band, called the epimysium, surrounds several fascicles. A perimysium surrounds an individual fascicle. An individual muscle fiber in a fascicle is invested in an endomysium.
