While examining a histological slide, a student observes muscle fibres that taper at both ends and lack any visible striations. Which of the following statements correctly describes the tissue identified?
Options
- AIt is attached to bones and is primarily responsible for voluntary movements.
- BIt contains specialized communication junctions called intercalated discs.
- CIt is located in the walls of hollow visceral organs and functions involuntarily.
- DIts functioning can be directly controlled by conscious thought.
Correct answer
C. It is located in the walls of hollow visceral organs and functions involuntarily.
Step-by-step solution
The muscle fibres that taper at both ends (fusiform shape) and lack visible striations are characteristic of smooth muscle tissue. Smooth muscle fibres are involuntary and are typically found in the walls of hollow visceral organs such as the stomach, intestines, and blood vessels. Skeletal muscles are striated and voluntary, and are attached to bones. Cardiac muscles are striated, involuntary, and contain intercalated discs. Answer: It is located in the walls of hollow visceral organs and functions involuntarily.
