When pairs of muscles work in opposite directions to move a limb, they are referred to as antagonistic muscles. One muscle, known as the agonist, contracts to produce movement, while the opposing muscle, the antagonist, relaxes to allow that movement to occur. This coordinated action enables smooth and controlled motion, as seen in activities like bending and straightening the arm. For example, when you flex your bicep, the tricep acts as the antagonist, relaxing to facilitate the movement.

What is it called when pairs of muscles work in opposite directions to move a limb?
Antagonists oppose or reverse the movement of a prime mover.The process would be known as Antagonistic.
Why are muscles in pais?
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.
How do our muscles move?
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.
List of two joint muscles in upper and lower limb?
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
What are the muscles that move limb inward?
adductor muscles
What do you need for a limb to move?
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.
What body parts that work in pairs to help your body?
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.
What muscles are supplied by the brachial plexus?
All the muscles of the upper limb
What body parts that work in pairs to help your body move?
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.
Muscles that bend a limb are known as?
flexors
How antagonist muscles act together to raise and lower a limb?
Antagonist muscles work in pairs to facilitate movement by contracting and relaxing in opposition to each other. When raising a limb, the agonist muscle (e.g., the biceps during arm flexion) contracts while the antagonist muscle (e.g., the triceps) relaxes, allowing for smooth movement. Conversely, when lowering the limb, the antagonist muscle contracts to control the descent, while the agonist relaxes. This coordinated action ensures stability and precision in limb movements.
What is body parts that work in pairs to help your body move?
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.
