An aggregation of many smooth muscle cells forms the contractile portions of various organs. Smooth muscle c.s. 4 Long spindle-shaped cells arranged so that the thin end of one cell is adjacent to the thickest portion of another cell. Thus in c.s. not all muscle fibers show nuclei at the same level. Usually one nucleus per cell located centrally.
Nuclear shape resembles the shape of the cell.
When the muscle contracts the nucleus assumes a corkscrew-like shape. 1 Long spindle-shaped cells arranged so that the thin end of one cell is adjacent to the thickest portion of another cell.
