Skeletal Muscle Tissue
- These muscles are attached to the skeleton and help in its movement.
- Skeletal are voluntary muscles composed of muscle fibers.
- The cells of these tissues are multinucleated.
- These are provided with blood vessels and many elongated mitochondria and glycogen granules.
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 involuntary muscles and the heart pumps the blood through cardiac contractions.
- They are single-celled and uninucleate.
- The ends of the cells are joined, and the junctions are called intercalated discs. The cells are attached to each other by desmosomes.
