muscles bend limbs by pulling, they can not push. the answer is; a muscle is a muscle.
Muscles move body parts by contracting and then relaxing. Your muscles can pull bones, but they can't push them back to their original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
adductor muscles
Upper limb: Biceps brachii and triceps brachii Lower limb: Quadriceps femoris and hamstrings
This type of muscle contracts to bend a limb at a joint
For a limb to move, you need muscles, nerves, and a signal from the brain. The brain sends signals through nerves to the muscles, which contract and allow the limb to move.
All the muscles of the upper limb
Muscles are in pairs as when one muscle contracts, its pair will relax, and the limb is moved. The reverse happens when the limb is returned to its starting position. Muscles can pull, but they can't push.
A muscle that straightens a joint is called an extensor.Extensors are the muscles whose contraction extends or straightens a limb or other part of the body.Extensor muscle
