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 is a phase of mitosis in which the nuclear membrane of the cell begins to dissapear and the mitotic spindle becomes visible under a microscope. This question is archived.
Mitosis is the simplest of the two ways (mitosis and meiosis) in which the nucleus of cells divide - as part of a process of cell division. The context in which mitosis occurs during the cell cycle is explained as follows:
