The cardiac muscles contain:
Correct answer: D. Myofibrils and Myofilaments of actin and myosin
- A. Myofibrils
- B. Myofilaments of actin
- C. Myofilaments of myosin
- D. Myofibrils and Myofilaments of actin and myosin
Explanation
The arrangement of cardiac muscle cells or fibres is similar to those in skeletal muscles fibre. These muscles also contains myofibrils and myofilaments of actin and myosin. The difference is that of branches and intercalated discs which are found in cardiac muscles fibres only.
