ANATOMY

Detailed explanation-1: -Myocytes, sometimes called muscle fibers, form the bulk of muscle tissue. They are bound together by perimysium, a sheath of connective tissue, into bundles called fascicles, which are in turn bundled together to form muscle tissue.

Detailed explanation-2: -The muscle tissue is comprised of specialized cells capable of contraction. These cells are called muscle cells (also called myocytes or muscle fiber). The muscle cell is also called the muscle fiber because it is long and tubular. The muscle cell develops from myoblasts through myogenesis.

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: -Skeletal muscles are substantially composed of multinucleated contractile muscle fibers (myocytes).

Detailed explanation-5: -The cells are long and slender so they are sometimes called muscle fibers, and these are usually arranged in bundles or layers that are surrounded by connective tissue. Actin and myosin are contractile proteins in muscle tissue.
