Structure of Skeletal Muscle. A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.n 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.
Connective Tissue Coverings. An individual skeletal muscle is separated from adjacent muscles and held in position by layers of dense connective tissue called fascia (fash'e-ah). This connective tissue surrounds each muscle and may project beyond the end of its muscle fibers to form a cordlike tendon.hese sections contain bundles of skeletal muscle fibers called fascicles (fasciculi). Each muscle fiber within a fascicle (fasciculus) lies within a layer of connective tissue in the form of a thin covering called endomysium (figs. 9.2 and 9.3).
