Cardiac and skeletal muscle both possess striations..
Although both cardiac and skeletal muscles are striated, skeletal muscle is composed of slow (type I) and fast (type II) fibers, whereas cardiac muscle consists of a single fiber type, most similar to type I skeletal muscle fibers. In contrast, smooth muscle cells are not striated but rather consist of dense bodies and intermediate filaments.

E. there is a small amount of smooth muscle in the heart. B. smooth muscle is found in the walls of hollow organs.There are three major types of muscle, and their structure reflects their function. Skeletal and cardiac muscle cells are called striated muscle because of the very regular arrangement of their intracellular contractile units, sarcomeres, at the light microscope (LM) and electron microscope (EM) levels. This regular arrangement imparts a cross-striated (or striped) appearance.Smooth muscle and cardiac muscle are similar in that they both A. are under involuntary control. ...

Skeletal muscle; What tissue subtype is striated and under voluntary control?There are striations in skeletal muscle. These are alternating dark and light bands perpendicular to the edge of the fiber that are present all along the fiber. Cardiac muscle is only found in the heart. Its fibers are longer than they are wide, and they are striated, like skeletal muscle fibers.Compared to the giant cylinders of skeletal muscle, cardiac muscle cells, or cardiomyocytes, are considerably shorter with much smaller diameters. Cardiac muscle also demonstrates striations, the alternating pattern of dark A bands and light I bands attributed to the precise arrangement of the myofilaments and fibrils that are organized in ...A sarcomere is the basic unit of muscle tissue in both cardiac and skeletal muscle. Sarcomeres appear under the microscope as striations, with alternating dark and light bands. Sarcomeres are connected to a plasma membrane, called a sarcolemma, by T-tubules, which speed up the rate of depolarization within the sarcomere.One of the most iconic images in biology is the cross-striated appearance of a skeletal muscle fiber. The repeating band pattern shows that all of the sarcomeres are the same length. All of the A bands are the same length and are located in the middle of the sarcomeres.

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.Striated musculature comprises of two types of tissues: skeletal muscle and cardiac muscle. Skeletal muscle is the tissue that most muscles attached to bones are made of. Hence the word "skeletal". Cardiac muscle, on the other hand, is the muscle found on the walls of the heart.
