Understanding Muscle Pairs
Muscles in the human body work in pairs, which is essential for movement. This process is known as antagonistic muscle action.
How Muscles Operate
- Muscles can only pull; they cannot push.
- When one muscle contracts, its paired muscle relaxes.
- This allows for efficient movement and control.
Contracting and Relaxing
- Contraction: When a muscle contracts, it shortens and pulls on the bone, creating movement.
- Relaxation: The paired muscle must relax to allow the joint to move back to its original position.
- This cycle of contraction and relaxation is crucial for smooth and coordinated movements.
Example: Bicep and Tricep
- Bicep: When you bend your arm, the bicep contracts.
- Tricep: At the same time, the tricep relaxes, allowing the arm to curl.
- When you straighten your arm, the tricep contracts, while the bicep relaxes.
Importance of Muscle Pairs
- This pairing helps maintain balance and stability in movements.
- It allows for more controlled and precise actions.
In conclusion, the correct answer is option 'C' because muscles work by contracting and relaxing in pairs, ensuring effective movement and coordination.
