the answer is when one muscle contracts the other relaxes
Yea hands are part of the skeletal system which works in pairs... The two pairs that they work with are extensor and flexors (:
Muscles work in pairs, so they must be equally strong to work together the right way. If strength is unbalanced, muscles may not properly work together.
pairs of muscles that work together
pairs of muscles that work together
Most muscles work in pairs, known as antagonistic pairs, where one muscle contracts while the other relaxes. However, some muscles, like the diaphragm, function independently to facilitate breathing without a direct opposing muscle. Additionally, certain muscles in the eye, such as the lateral and medial rectus, can also work in a more coordinated manner rather than strictly in pairs. Overall, while the majority of skeletal muscles operate in pairs, there are exceptions based on their specific functions.
Muscles always work in pairs, known as antagonistic pairs. When one muscle contracts (the agonist), the opposing muscle relaxes (the antagonist) to allow movement. For example, when you flex your bicep, the tricep relaxes, and vice versa. This coordinated action ensures smooth and controlled movements throughout the body.
they are called antagonistic muscles.
Skeletal muscles work in pairs: flexors and extensors
Muscles cannot push, they can only pull which means they work in pairs in order to move, this is known as antagonistic pairs. For example with a bicep curl you have the agonist/ prime mover (Bicep) and the antagonist/ Opposing muscle group (Triceps). As the agonist contracts it pulls the antagonist which relaxes.
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
A muscle is either contracting (doing work) or relaxing (not under tension). Some muscles do not ever completely relax under normal conditions.
