What movement does the arm make when the triceps muscle contract?
The biceps muscle relaxes!!!!!=)
What does one muscle do while the other one relaxes?
contracts - for antagonistic muscle pairs e.g. muscles in arm (when one relaxes, other contracts, and vice versa)
What movement occurs when the triceps contract?
The biceps muscle relaxes!!!!!=)
where in the muscles would you find triceps?
They are the opposite muscle to the biceps. If you bend your arm to make the muscle on the top (the biceps) bulge, the muscle on the bottom (the triceps) relaxes. The triceps is on the back of your arm, and is used to straighten the elbow.
How do skeletal muscles work as a pair to bend and straighten the arm at the elbow?
When you bend your elbow, the biceps muscle contracts. At the same time the antagonist muscle, that is the triceps muscle relaxes in synchronized manner. Vise verse action take place, when you straighten the arm at the elbow. Triceps contracts and biceps relaxes.
What muscle extends the arm in a push-up?
break throw muscle shrug write
How your arm uses muscles to move?
Your arm uses its bicep and tricep muscle to move. Muscles can only contract so they have to work in pairs. Ex. Bicep and tricep One muscle contract, the other relaxes
What is the top muscle in your arm called?
If you're talking about the one that everyone's always asking for when they say, "Make a muscle!" then it's your BICEP. The bicep is the muscle that contracts when the arm is bent, and the tricep is the one that relaxes.
What happens to the muscle as the arm moves down?
One group of muscles contracts, and the other group extends. As an arm moves down, the bicep muscle (the one that faces the front side of the body and goes from the shoulder to the elbow) relaxes. When the muscle relaxes, it goes from being contracted to elongated. This relaxation happens at the same time that the tricep muscle (the one that faces the backside of the body and goes from the shoulder to the elbow) contracts. This happens because the human body's skeletal muscles have what can be considered compliments. I say this to mean that when a muscle relaxes, there is a muscle that contracts simultaneously. Therefore, they move antagonistically to each other. This is to serve the purpose of creating specific movements that help assist in locomotion. On the molecular level of what happens when a muscle contracts and relaxes, the actin and myosin filaments in muscle fiber overlap to contract and separate to relax.
As one muscle in a pair relaxes what does the otyher muscle do?
contract
When one muscle contracts what dose the other muscle do?
Relaxes
In a muscle group the muscle that relaxes during a particular action is what?
