Figure 6.3.2 6.3. 2: Muscle type 1) Skeletal muscle cells are long tubular cells with striations (3) and multiple nuclei (4). 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.Action potentials are considerably different between cardiac pacemaker cells and cardiac muscle cells. While Na + and K + play essential roles, Ca 2+ is also critical for both types of cells. Unlike skeletal muscles and neurons, cardiac pacemaker cells do not have a stable resting potential. Pacemaker cells contain a series of Na + channels ... Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.

The striations seen in skeletal muscle are actually alternating dark A and light I bands. true. Thick filaments are made of a protein called actin.Cardiac Muscle. Cardiac muscle, shown in Figure 1, is found only in the heart. Like skeletal muscle, it has cross striations in its cells, but cardiac muscle has a single, centrally located nucleus. Cardiac muscle is not under voluntary control but can be influenced by the autonomic nervous system to speed up or slow down.Intermediate filaments are major components of the cytoskeleton. Desmin and synemin, cytoplasmic intermediate filament proteins and A-type lamins, nuclear intermediate filament proteins, play key roles in skeletal and cardiac muscle. Desmin, encoded by the DES gene (OMIM *125660) and A-type lamins by the LMNA gene (OMIM *150330), have been involved in striated muscle disorders.skeletal muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other.Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated ...

Skeletal muscle controls the body's movement and is generally under conscious, or voluntary, control. The internal organs, on the other hand, with the exception of the heart, are made of smooth muscle, which works without conscious effort.
