Cardiac and skeletal muscle both possess striations..
Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (Figure 10.21). However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell.

Cardiac muscle also called the myocardium, is one of three major categories of muscles found within the human body, along with smooth muscle and skeletal muscle. Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. 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.Although they do not have striations and …Muscles that have actin and myosin filaments arranged in large bundles that are parallel a) Are found in the stomach, intestine, and uterus b) Are found in smooth muscle c) Are found in skeletal and cardiac muscles d) Lack striations; A skeletal muscle is composed of a bundle of, each composed of many muscle fibers wrapped by connective tissue. a.There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Skeletal muscle cells are long, cylindrical, multi-nucleated and striated . Each nucleus regulates the metabolic requirements of the sarcoplasm around it. Skeletal muscle cells have high energy requirements, so they contain many mitochondria in order to …Developing skeletal muscles express unique myosin isoforms, including embryonic and neonatal myosin heavy chains, coded by the myosin heavy chain 3 (MYH3) and MYH8 genes, respectively, and myosin light chain 1 embryonic/atrial, encoded by the myosin light chain 4 (MYL4) gene.

This type of tissue occurs in the muscles that are attached to the skeleton. florida biology eoc scores Both smooth and skeletal muscle possesses actin and myosin. In fact, the crossbridge cycle is identical in both smooth and skeletal muscle. The differences in the two muscle types are the neuronal regulation, the calcium binding proteins they possess and the mode of calcium entry into the cytoplasm of the cells.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. Such an arrangement is not seen in smooth muscle ...1.7.1 Structure of cardiac muscle.
