NEET PG DENTAL EXAM

Detailed explanation-1: -When one of them contracts, the bone is pulled in that direction and the other muscle of the pair relaxes. To move the bone in the opposite direction, the relaxed muscle contracts and the first one relaxes. Thus two muscles have to work together to move a bone.

Detailed explanation-2: -Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors.

Detailed explanation-3: -Muscles work in pairs: as one muscle contracts, the other relaxes. Muscles that work together like this are called antagonistic pairs. This type of action enables the body to move with stability and control.

Detailed explanation-4: -The three main types of muscle include skeletal, smooth and cardiac. The brain, nerves and skeletal muscles work together to cause movement – this is collectively known as the neuromuscular system.
