Question

Identify the type of muscles shown in the following figure.

• A. a – Smooth muscle, b – Cardiac muscle, c – Skeletal muscle
• B. a – Skeletal muscle, b – Smooth muscle, c – Cardiac muscle
• C. a –Cardiac muscle, b – Smooth muscle, c – Skeletal muscle
• D. a – Smooth muscle, b – Skeletal muscle, c – Cardiac muscle

Answer 1

The correct option is B a – Skeletal muscle, b – Smooth muscle, c – Cardiac muscle

• Muscular tissue consists of contractile elongated cells also called muscle fibres. They are of three types: Skeletal, smooth and cardiac.
• The cells of skeletal muscle tissues show alternate dark and light bands called striations. They are long, cylindrical, unbranched and multinucleate (having many nuclei). Skeletal muscles are mostly attached to the bones and help in body movement.
• Smooth muscles are non striated, spindle shaped and help in involuntary movements.
• Cardiac muscles show striations and are branched.These muscles make up the heart and enable the heart to pump blood by continuous contraction and relaxation.
