Question: 1 / 580

Which muscle is primarily responsible for flexing the forearm?

Tricep

Bicep

The muscle primarily responsible for flexing the forearm is the bicep. The biceps brachii, commonly referred to as the bicep, is located in the upper arm and plays a key role in flexing the elbow, which brings the forearm closer to the upper arm. This muscle works effectively during activities that require lifting or pulling movements.

In contrast, the triceps muscle is involved in the extension of the forearm, acting as the antagonist to the biceps during elbow movements. The deltoid muscle primarily acts on the shoulder joint for arm abduction and does not have a significant role in forearm flexion. The latissimus dorsi is a large muscle of the back that aids in shoulder movements, but it is not directly engaged in flexing the forearm. Thus, the bicep is the clear choice as it is specifically designed to perform this function.
