There are three types of muscle in the body: skeletal (the muscles used to move the skeleton), cardiac (the muscle in the heart), and smooth (the muscle used for unconscious things like digestions and continence). Each has specialised cell adaptations. ANP and BNP are released from cardiac muscle when it is placed under stress.Skeletal Muscle. Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins actin and myosin. These muscle cells are relatively long and have multiple nuclei along the edge of the cell. Skeletal muscle is under voluntary, somatic nervous system control and is found in the muscles that move bones.Figure 38.33 The body contains three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle, visualized here using light microscopy.
