Three type of muscles are given as a, b and c. Identify the correct matching pair along with their location in human body.

A (a) Skeletal - Biceps; (b) Involuntary - Intestine; (c) Smooth - Heart.
B (a) Involuntary - Nose tip; (b) Skeletal - Bone; (c) Cardiac - Heart.
C (a) Smooth - Toes; (b) Skeletal - Legs; (c) Cardiac - Heart.
D (a) Skeletal - Triceps; (b) Smooth - Stomach; (c) Cardiac - Heart

The answer is D.

Solution

(a) Striated, unbranched fibres bundled in parallel – skeletal muscle, e.g. triceps/biceps.
(b) Spindle-shaped, non-striated fibres – smooth muscle, found in the walls of internal organs such as the stomach and intestine.
(c) Striated, branched fibres with intercalated discs – cardiac muscle, found only in the heart.
So (a) Skeletal – Triceps, (b) Smooth – Stomach, (c) Cardiac – Heart.

Concept Matching skeletal, smooth and cardiac muscle micrographs to body locations
