The bicep on the front and the tricep on the back.
The tricep contracts and the bicep relaxes.
Yes your tricep and bicep both work together to help bend your arm.
The tricep
The tricept is located under the bicept.Sorry, however the tricep is just the muscle at the lower arm.The bone under the bicep is the humerus.***If you are asking this for the answer to a crossword puzzle, the correct answer is ULNA***
tricep
I think what your after is called an antagonistic pair of muscles, for example the bicep and the tricep. When the bicep is contracting the tricep relaxes and when the tricep is contracting the bicep relaxes.
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
The Bicep muscle (one on top) is contracting The Tricep muscle (one below) if relaxing The Bicep and Tricep muscles are antagonistic- they work as opposites, so when one contracts, the other relaxes.
The muscles are moving antagonistically.
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
The tricep is the muscle on the underside of the upper arm. The muscle on the upper side is the bicep.
