GENERAL HISTOLOGY

Detailed explanation-1: -Each skeletal muscle fiber is a single cylindrical muscle cell. An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium .

Detailed explanation-2: -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. Muscles are composed of long bundles of Myocytes (Muscle fibers).

Detailed explanation-3: -Skeletal muscle cells A single muscle such as the biceps in a young adult male contains around 253, 000 muscle fibers.

Detailed explanation-4: -A muscle cell or fiber is composed of myofibrils whose fundamental repeating unit is the sarcomere. All views are longitudinal except the cross-sections of the sarcomere (G, H, I). FIGURE 46.3. Electron micrographs and diagrams of sarcomeres at various muscle lengths.
