Answer
| Basis | Striated (Skeletal) Muscles | Unstriated (Smooth) Muscles | Cardiac Muscles |
| Structure | Long, cylindrical, unbranched, and have many nuclei (multinucleate). They show alternate light and dark bands (striations). | Spindle-shaped (pointed ends), unbranched, and have a single nucleus (uninucleate). They do not show bands. | Cylindrical, branched, and have a single nucleus (uninucleate). They show faint bands. |
| Site / Location | Attached to bones (limbs, hands, legs). | Found in the walls of internal organs like the stomach, intestine, bronchi, and iris of the eye. | Found only in the walls of the heart. |
