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.
Within muscle tissue are three distinct groups of tissues: skeletal muscle, cardiac muscle, and smooth muscle. Each of these tissue groups is made of specialized cells that give the tissue its unique properties. Skeletal muscle is the most common and widely distributed muscle tissue in the body, making up around 40% of the bodyâs total mass.
