Biceps brachii and triceps how do they work together?

The biceps brachii and triceps brachii muscles work together to control movement at the elbow joint. The biceps brachii is located on the front of the upper arm, while the triceps brachii is located on the back.

The biceps brachii muscle is responsible for flexing the elbow, while the triceps brachii muscle is responsible for extending the elbow. When the biceps brachii contracts, it pulls the forearm upwards, causing the elbow to bend. When the triceps brachii contracts, it pulls the forearm downwards, causing the elbow to straighten.

The biceps brachii and triceps brachii muscles work together to provide stability and strength to the elbow joint. They help to keep the joint in place and prevent it from dislocating. They also help to slow down the movement of the elbow joint, which can help to prevent injuries.

In addition to working together to control movement at the elbow joint, the biceps brachii and triceps brachii muscles also work together to perform other movements of the upper arm. For example, the biceps brachii muscle helps to rotate the forearm, while the triceps brachii muscle helps to extend the shoulder.

By working together, the biceps brachii and triceps brachii muscles help to create a wide range of movement and stability in the upper arm.
