The biceps and triceps are used to bend and extend the elbow. When your biceps contract it bends the elbow and when the triceps contract it extends the elbow. Also, when the biceps contracts, the triceps relaxes - and vice versa.
almost all muscles work in pairs. one contracts while the other one relaxes. so as you contract your biceps (or flex it) your triceps are relaxing allowing and helping your biceps to contract.
The whole answer is waaay too long for a discussion here but if you really want to know I can tell you 2 things that will help you in your research: 1 - Muscles only PULL. They never push. For example to bend at your elbow like when you lift weights (bicep curl) your biceps is pulling on your bones. When you lower your arm back down your triceps is pulling on the bones to bring your arm down. Neither the bicep nor the tricep pushes on the bones. 2 - The biceps and triceps are antagonists. They act opposite each other. When the biceps is pulling on your bones to perform a bicep curl your tricep is relaxing. When you lower your arm back down your triceps contracts and your biceps relaxes. Again, that's a simplification and I don't know how in depth you're trying to get. There are whole semesters of classes people take to learn how muscles work together.
One contracts down and the other helps it contract up
Both the biceps and the triceps do pushing and pulling. They both play a major role in everyday activities.
Biceps and Triceps are not involved in the motion of the body. It is your legs and the muscles in your leg that help you move around
The Triceps brachii
Antagonist muscles are muscles that counteract the action of agonist muscles.Some examples of antagonist muscles are:Triceps work opposite of biceps.Hamstrings works opposite of quadriceps.The sternocleidomastoid works opposite of the deltoids.
When you flex your arm your biceps contract, and your triceps extend. And when you unflex your arm the triceps contract and you biceps extend. The muscles work together to allow you to move your body.
The biceps flexes the arm it does not extend it (straightens). The triceps brachii extends the arm. They do work together. If one is damaged and doesn't work as it should, the movement will be "jerky" and not smooth.
i am not sure but it might have something to do with your triceps and biceps
The triceps work together with the biceps. They form an antagonistic pair, which means that when one contracts the other relaxes, in order to move your bones. When the biceps are contracting, the triceps are relaxed, and stretches back to its original position. The opposite happens when the triceps contract.

to move arm upwards, the biceps contracts. Triceps don't do any work here~
two muscels biceps and triceps push and pull one contracts and one relax...
