Thick filaments are made of a protein called actin.Smooth muscle is one of three types of muscle tissue, alongside cardiac and skeletal muscle. It is a non-striated muscle tissue, lacking the characteristic markings seen in other types. Smooth muscle is found in numerous bodily systems, including the ophthalmic, reproductive, respiratory and gastrointestinal systems, where it functions to contract and cause movements not under voluntary control.

Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary, like those of smooth muscle. Cardiac muscle, like skeletal muscle, is arranged in bundles, so it appears striated, or striped.Smooth muscle is non-striated, although it contains the same myofilaments they are just organized differently, and involuntary.

Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Although they do not have striations and sarcomeres, smooth muscle fibers do have actin and myosin ...Cardiac muscle also demonstrates striations, the alternating pattern of dark A bands and light I bands attributed to the precise arrangement of the myofilaments and fibrils that are organized in sarcomeres along the length of the cell (Figure 19.2.1a). These contractile elements are virtually identical to skeletal muscle.Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Although they do not have striations and sarcomeres, …Skeletal muscle is an excitable, contractile tissue responsible for maintaining posture and moving the orbits, together with the appendicular and axial skeletons. It attaches to bones and the orbits through tendons. Excitable tissue responds to stimuli through electrical signals.
