explain the 3 type of muscular tissue on the basis of shape, location , function. please tell
Answers
Answer:
Skeletal Muscle Tissue ;These muscles are attached to the skeleton and help in its movement. These muscles are also known as striated muscles because of the presence of alternate patterns of light and dark bands. These light and dark bands are sarcomeres which are highly organized structures of actin, myosin, and proteins. These add to the contractility and extensibility of the muscles. Each skeletal tissue contains myofibrils. The cells of these tissues are multinucleated.
Smooth Muscle Tissue ;These are non-striated, involuntary muscles controlled by the Autonomous Nervous System. It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways. The actin and myosin filaments are very thin and arranged randomly, hence no striations.The cells are spindle-shaped with a single nucleus.
Cardiac Muscle Tissue ;These are found only in the heart. These are involuntary muscles and the heart pumps the blood through cardiac contractions. The cells of the cardiac muscles known as the cardiomyocytes are striated. They are single-celled and uninucleated. The ends of the cells are joined and the junctions are called intercalated discs. The cells are attached to each other by desmosomes.
