Question: 161. Three types of muscles are given as \mathrm{a}, \mathrm{b} and c . Identify the correct matching pair along with their location in human body:
Name of muscle/location
(1) (a) Smooth-Toes
(b) Skeletal-Legs
(c) Cardiac – Heart
(2) (a) Skeletal – Triceps
(b) Smooth – Stomach
(c) Cardiac – Heart
(3) (a) Skeletal – Biceps
(b) Involuntary – Intestine
(c) Smooth – Heart
(4) (a) Involuntary – Nose tip
(b) Skeletal – Bone
(c) Cardiac – Heart
Answer: Option (2)
Explanation:
Muscle type (a) shows long, cylindrical, striated and multinucleate fibers,
which are characteristic of skeletal muscles.
Skeletal muscles are voluntary muscles attached to bones,
such as the triceps muscle of the arm.
Muscle type (b) consists of spindle-shaped, non-striated fibers,
indicating smooth muscle.
Smooth muscles are involuntary and are found in visceral organs like the stomach and intestine.
Muscle type (c) shows branched striated fibers with intercalated discs,
which are characteristic of cardiac muscle.
Cardiac muscle is involuntary and is found only in the heart.
Therefore, the correct matching is (a) Skeletal–Triceps, (b) Smooth–Stomach,
and (c) Cardiac–Heart, corresponding to option (2).
