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.Skeletal muscles vary considerably in size, shape, and arrangement of fibers.ach 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.

Prophase. The first division of Mitosis in which the chromosomes become visible. The nuclear membrane begins to dissolve. Metaphase. The second stage of mitosis in which the chromosomes line up along the middle of the cell.uestion. Answer. Mitosis. The first stage of cell division in which the nucleus divides. Mitosis results in the formation of two daughter cells with exactly the same genetic information as the parent cell. Mitosis results in the production of two identical diploid cells.
