Answer:
Correct answer: (2): Contain multinucleated muscle fibers.
Explanation:
- The calf muscles of humans belong to the skeletal muscle system.
- Skeletal muscle forms the support element of the entire bone structure.
- It is voluntary in nature and can be controlled at our will and help in the movement of our entire body.
- The characteristic features of skeletal muscle include striations throughout the length of the muscle, they are multi-nucleated and lie directly beneath the sarcolemma.
- The interaction of actin and myosin helps in the contraction of muscles and thus the movement.
