Smooth muscle number of nuclei

Nov 4, 2023 · Skeletal muscle histology. This type of tissue is found in skeletal muscles and is responsible for the voluntary movements of bones. 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.

A smooth muscle cell is a spindle-shaped myocyte with a wide middle and tapering ends, and a single nucleus. Like striated muscle, smooth muscle can tense and relax. In the relaxed state, each cell is 30–200 micrometers in length, some thousands of times shorter than a skeletal muscle cell. [1]The nuclei are embedded in the cell membrane (5) to be just inside the cell. This type of tissue occurs in the muscles that are attached to the skeleton.
