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.

∙ 13y agoalmost 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.

∙ 14y agoThe 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.

∙ 9y agoBoth the biceps and the triceps do pushing and pulling. They both play a major role in everyday activities.

Why the biceps alone cannot make the arm straighten?
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.
What muscle work with triceps muscles to bend?
i am not sure but it might have something to do with your triceps and biceps
How does a tricep work?
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.
