Which of the following characters is shared by both skeletal and cardiac muscles?
- A. Presence of striation
- B. Involuntary control
- C. Multinucleated fibers
- D. Intercalated discs
Explanation
Both use the same regular arrangement of actin and myosin filaments, so both show cross striations under the microscope. They differ in control, skeletal being voluntary and cardiac involuntary, and intercalated discs and branching belong to cardiac muscle alone. Multinucleated fibres are a skeletal muscle feature.
