MICROANATOMY

Detailed explanation-1: -Each compartment contains a bundle of muscle fibers. 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: -Each muscle is made up of groups of muscle fibers called fascicles surrounded by a connective tissue layer called perimysium.

Detailed explanation-3: -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-4: -When a group of muscle fibers is “bundled” as a unit within the whole muscle it is called a fascicle. Fascicles are covered by a layer of connective tissue called perimysium (see Figure 10.2. 1). Fascicle arrangement is correlated to the force generated by a muscle and affects the muscle’s range of motion.

Detailed explanation-5: -Each fascicle (or fasciculus) is a bundle of muscle fibers, also called myocytes, bound together via the endomysium tissue that provides pathways for the passage of blood vessels and nerves.
