The biceps brachii is a muscle located in the upper arm, primarily responsible for flexing the elbow and supinating the forearm. In contrast, the external oblique is found in the abdominal region and plays a key role in trunk rotation and lateral flexion, as well as providing support for the abdominal wall. These muscles differ in their location, function, and the movements they facilitate in the body.
