Smooth muscle number of nuclei.

Muscle, one of the four basic tissues of the body, is specialized for contraction. The cells that comprise muscle tissue are referred to as muscle fibers or myocytes. The three types of muscle fibers are compared in this diagram. Skeletal muscle is at the top, cardiac muscle is in the center and smooth muscle is in the lower panel. Longitudinal ...Cardiac myocytes are shorter than skeletal equivalents and contain only one or two centrally located nuclei. Smooth Muscle Tissue.

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, …

Muscle Tissues. There are three types of muscle in animal bodies: smooth, skeletal, and cardiac. They differ by the presence or absence of striations or bands, the number and location of nuclei, whether they are voluntarily or involuntarily controlled, and their location within the body.
