Smooth muscle myofibrils
WebSmooth muscles are found in the walls of hollow viscera and blood vessels. It is called smooth because it has no cross striations, involuntary because its contraction can not be elicited at will and visceral because they are found … WebExplain the role of muscles in locomotion. Muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion. The body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 1). Figure 1.
