Which characteristic is typical of smooth muscle rather than skeletal muscle?
Correct answer: C. Spindle-shaped cells without visible striations
- A. Long, cylindrical, multinucleated fibres
- B. Voluntary control through somatic nerves
- C. Spindle-shaped cells without visible striations
- D. Rapid contraction attached directly to bones
Explanation
Smooth muscle has spindle-shaped cells, a single central nucleus, and no visible striations. It is involuntary and is found in structures such as the intestines and blood vessels.

About Skeletal and Muscular Systems
The skeletal and muscular systems include bone structure, joints, cartilage, the axial and appendicular skeleton, and the roles of ligaments and tendons. They also cover skeletal muscle organization, the sliding filament mechanism, neuromuscular contraction, and common differences between voluntary skeletal muscle, cardiac muscle and smooth muscle.
