GROSS ANATOMY

Detailed explanation-1: -The brachialis is an elbow flexor that originates from the distal anterior humerus and inserts onto the ulnar tuberosity. The brachialis is one of the largest elbow flexors and provides pure flexion of the forearm at the elbow. [2] It does not provide any supination or pronation of the forearm.

Detailed explanation-2: -Function. The brachioradialis flexes the forearm at the elbow. Depending on the position of the hand during the flexion, the brachioradialis can tend to move the hand to neutral.

Detailed explanation-3: -The brachioradialis is a superficial forearm muscle located in the lateral forearm. The brachioradialis primarily flexes the forearm at the elbow but also functions to supinate or pronate depending on the rotation of the forearm.
