Answer:

Striated Muscles: Striated muscles fibres are long or elongated,unbranched,have many nuclei. Each muscle cell is enclosed in a thin but distinct plasma membrane called sarcolemma. These muscles are present in limbs,face,neck,tongue,pharynx,diaphragm. It help in smooth contraction and movement.

Non-Striated: 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 muscles: are involuntary muscles. They are involved in continuous rhythmic contraction and relaxation.

Cardiomyocytes or the cardiac cells are uninucleate, cylindrical, and elongated.

Cardiac muscles display faint cross-striations which do not get fatigued under normal circumstances.
