Examples

  •  We learned the names of the bones making up the axial and appendicular portions of the skeleton  We considered the tissues of the bones and joints (compact bone, spongy bone, cartilage, fibrous connective tissue)  We learned the names of various muscles and how they operate when we intentionally move our bones  We can't understand how skeletal muscles contract and move the bones until we study skeletal muscles at the cellular level  A muscle cell is suited to its task because it contains contractile organelles called myofibrils

  • Striated muscle tissue consists of bundles of fibers called fasiculi made up of long nucleated cells with myofibrils in alternating dark and light bands that give them a striped appearance.

  • The authors concluded that CK-2017357 selectively sensitizes the ATPase activity of skinned fast skeletal myofibrils to calcium, without significant activation of myofibrils from slow skeletal or cardiac tissue.
