Which among the following is NOT a type of "muscle tissue"?

The correct answer is Option (4) → Areolar

The question asks for the tissue that is NOT a muscle tissue. Muscle tissue is made of long cells (muscle fibres) that contract and relax to bring about movement.

Option (1) Cardiac — A muscle tissue (Incorrect). Cardiac muscle forms the wall of the heart; its branched, striated cells contract rhythmically throughout life without tiring.

Option (2) Striated — A muscle tissue (Incorrect). Striated (skeletal or voluntary) muscle is attached to bones and shows light and dark bands; it moves under our control.

Option (3) Unstriated — A muscle tissue (Incorrect). Unstriated (smooth or involuntary) muscle has spindle-shaped cells without bands; it lines the stomach, intestine and blood vessels and works without our control.

Option (4) Areolar — Not a muscle tissue (Correct). Areolar tissue is a connective tissue found between the skin and muscles and around blood vessels and nerves; it fills spaces inside organs, supports them and helps repair tissues.
