If you pull on a chicken's wing muscles, they will likely resist and try to pull it back. If you pull it against their will to forcefully you could injure the bird.
When you pull on one of the arm muscles in the chicken wing, the muscle fibers are stretched. If the force applied exceeds the muscle's capacity, the muscle may tear or rupture. This can result in pain, inflammation, and loss of function in that muscle.
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.
all of them, muscles can only contract and relax
the muscle gets pulled
by having groups of muscles. one pulling one way one pulling the other way
one muscle to contract and the other muscle to retract
Skeletal muscles work in pair because of the limitation that these muscles can only contract or pull and can only move in one direction.
Muscles never "push"; they can only "pull".The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
Skeletal muscles work in pairs to move a bone so that the muscles can function properly. Muscles can only pull, therefore bones need two muscles to make it move. To put a finger up one muscle might pull, the other will put to put back down. With two, the movement will be smooth, otherwise it will be "jerky" and uncontrolled.
Skeletal muscles work in pairs because muscles can only contract (pull) and cannot expand (push). Thus, if you want to move one direction, you use one set of muscles and to move in the opposite direction you use the corresponding set of muscles.skeletal muscles work in pairs because muscles can only contract (pull) and cannot expand (push).Skeletal muscles will have a flexor and an extensor.The flexor bends the joint.The extensor straightens it out again.Skeletal muscles work in pairs because muscles can only contract (pull) and cannot expand (push). Thus, if you want to move one direction, you use one set of muscles and to move in the opposite direction you use the corresponding set of muscles.
muscles can only pull so a bone with only one muscle on it would be pulled to the extreme of the muscles contraction and stay there.
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
