Difference Between Cardiac Skeletal and Smooth Muscle

WebCardiac muscle cells are branched and much smaller than skeletal muscle cells. In addition, cardiac muscle cells are connected end-to-end by special structures called intercalated discs (in-ter’kă-lā-ted). Intercalated discs allow the cells to communicate with each other. To keep communication links open between cells the intercalated discs WebAnother difference between the two types of muscle is their structure. Cardiac muscle cells are shorter and thicker than skeletal muscle cells, and they have a single, centrally located nucleus. Skeletal muscle cells, on the other hand, are longer and thinner, and they have multiple nuclei located near the cell's periphery. iphone outlook pdf 見れない

Web1 dec. 2003 · Smooth muscle derives its name from the fact that it lacks the striations characteristic of cardiac and skeletal muscle. Layers of smooth muscle cells line the walls of various organs and tubes, and the contractile function of smooth muscle is not under voluntary control. WebCardiac muscle owes its striated appearance to the arrangement of thick and thin filaments that make up the contractile apparatus. Electron micrographs of cardiac muscle reveal a banding pattern of myofibrils similar to that observed for skeletal muscle. Like skeletal muscle, these bands are referred to as the A band, I band, and Z disk.
