Question -
How do muscles help in movement of the body? [3 MARKS]
Answer:
:
The working of muscles: 1 Mark each
1. The muscles work in pairs.
2. When one of them contracts, the bone is pulled in that direction, the other muscle of the pair relaxes. To move the bone in the opposite direction, the relaxed muscle contracts to pull the bone towards its original position, while the first musclerelaxes.
3. A muscle can only pull. It cannot push.
