Explain different types of muscular tissue

Striated

• The cells are long, cylindrical, unbranched and multinucleate (having many nuclei).
• These muscles are called voluntary muscles, because they show movement when we want.
• These muscles are also called skeletal muscles.
• They are mostly attached to bones and help in body movement.
• These muscles show alternate light and dark bands or striations when observed under the microscope, due to this reason they are also called striated muscles.

Smooth/unstriated 

• The cells are long with pointed ends (spindle-shaped) and uninucleate (having a single nucleus).
• They are also called unstriated muscles.
• They are under the control of involuntary muscles.
• The movement of food in the alimentary canal or the contraction and relaxation of blood vessels are involuntary movements.
• They are also found in the iris of the eye, in ureters and in the bronchi of the lungs.

Cardiac

• The muscles of the heart are involuntary in nature and called cardiac muscles.
• The cells are cylindrical in shape, branched and uninucleate.
• The heart muscles show rhythmic contraction and relaxation throughout life.
