Which of the following statements is correct regarding muscle tissues in humans?
Options
- ASkeletal muscle fibres are fusiform in shape and lack visible striations under a microscope.
- BCardiac muscle cells are unbranched and their functioning can be consciously controlled.
- CSmooth muscle fibres taper at both ends and are found in the walls of the intestine and blood vessels.
- DCommunication junctions in smooth muscles allow the entire tissue to contract as a single unit.
Correct answer
C. Smooth muscle fibres taper at both ends and are found in the walls of the intestine and blood vessels.
Step-by-step solution
Skeletal muscle fibres are cylindrical, multinucleated, and striated. They are voluntary in nature. Cardiac muscle cells are branched, striated, and involuntary. They possess communication junctions (intercalated discs) that allow the cells to contract as a single unit. Smooth muscle fibres are fusiform (taper at both ends), non-striated, and involuntary. They are found in the walls of hollow internal organs such as blood vessels, stomach, and intestine. Answer: Smooth muscle fibres taper at both ends and are found
