Quick Summary

Illustration of the human forearm from an anterior view, showing the superficial layer of muscles, tendons, and ligaments.

Muscles of the human forearm The forearm contains flexor and extensor muscles, which help control fine movements of the wrist, hand, and fingers.

The brachialis muscle is located in the upper arm, beneath the biceps brachii. It plays a crucial role in the movement of the forearm, specifically in flexion, which is the action of decreasing the angle at the elbow and bringing the hand closer to the shoulder. The brachialis, along with the biceps brachii and brachioradialis, are the primary muscles responsible for this movement. The brachialis muscle, along with the biceps, bends the arm at the elbow.12
