All muscle cells contain striations..

All muscles, regardless of the particular type, can contract— that is, shorten. When muscles contract, some part of the body or the entire body moves. Humans have three types of muscles: smooth, cardiac, and skeletal (Fig. 7.1). The contrac- tile cells of these tissues are elongated and therefore are called.The actin and myosin proteins are arranged very regularly in the cytoplasm of individual muscle cells (referred to as fibers) in both skeletal muscle and cardiac muscle, which creates a pattern, or stripes, called striations. The striations are visible with a light microscope under high magnification (see Figure 10.2).Figure 3.5.2 3.5. 2: Histology of Muscle Tissue Types at 400x. (a) Skeletal muscle cells have prominent striations and nuclei on their periphery. (b) Smooth muscle cells have a single nucleus and no visible striations. (c) Cardiac muscle cells appear faintly striated and have a single nucleus.Note that sometimes the cross striations are not aligned all the way across the cell. This is because different myofibrils may not be aligned. In transverse sections of skeletal muscle cells (slide 58), observe the cylindrical shape of the cells (fibers) and the peripherally-located nuclei. ... Some skeletal muscle cells on your slide may be ...

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. Contractile tissue is able to generate tension of force.
