GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -fascia: A sheet of thick connective tissue which surrounds a muscle. endomysium: A sheet of connective tissue which wraps each fascicle. fascicle: A group of muscle of fibers surrounded by the perimysium.

Detailed explanation-3: -Each muscle fiber (cell) is covered by endomysium and the entire muscle is covered by epimysium. 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.
