Because Muscles only pull not push
antagonistic muscles
the answer is when one muscle contracts the other relaxes
they are pairs of muscle that work together alternating. they need each other because no muscle can stretch a so the other mucle contracts.
Because muscle cells can only contract, not extend, skeletal muscles most work in pairs. While one muscle contracts, the other muscle in the pair relaxes to its original length.
Muscles can only exert force by getting shorter. Muscles work in pairs by one muscle pulling in one direction, the other muscle pulls in the opposite direction. One bends your leg, the other straightens the leg, etc.
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
Antagonistic muscle pairs work together to maintain balance and stabilize the body. When one muscle contracts, its antagonist muscle relaxes to allow movement. For example, the biceps and triceps work together to bend and straighten the arm, contributing to overall stability and posture.
Because muscle can only contracts. The only way for it to lengthen is by having an outside force, ie, another muscle's contraction.
They are the muscles. Muscles contract in pairs to move the parts across the joint. One muscle contract with more power. The opposite muscle contracts with less power and get stretched over to allow the first muscle to act.
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
Agnostic muscle pairs are muscle groups that work together in a way that they can function independently of each other. They are not reliant on each other during movement, allowing for more flexibility and movement efficiency. Examples include the biceps and triceps in the arms, or the hamstrings and quadriceps in the legs.
