This means that cardiac tissue will have far more irregular shapes than skeletal muscles. Cardiac muscle cells contain T tubules that connect to the sarcoplasmic reticulum which stores the calcium ions needed for the contraction of the cell. Skeletal Muscle. Skeletal muscle has striations across its cells caused by the arrangement of the contractile proteins actin and myosin.

The striations are visible with a light microscope under high magnification (see Figure 10.1.1). Smooth muscle (named for it ...Each skeletal muscle cell, also called a muscle fiber, develops as many embryonic myocytes fused into one long, multi-nucleated skeletal muscle cell. These muscle fibers are bound together into bundles, or fascicles, and are supplied with a rich network of blood vessels and nerves. The fascicles are then bundled together to form the intact muscle. Abstract. The striated muscle cell cytoskeleton is a multifunctional, dynamic, and complex structure that serves as a scaffold to maintain the structural integrity and architecture of the cell.
