Where does the flexor carpi radialis insert?

The flexor carpi radialis is a muscle of the forearm that plays a pivotal role in wrist flexion and radial deviation. It originates from the medial epicondyle of the humerus and has its insertion at the bases of the second and third metacarpals. This specific insertion allows the flexor carpi radialis to facilitate actions like wrist flexion and contributes to the movement of the hand towards the thumb side, which is referred to as radial deviation.

In terms of anatomical relevance, the insertion at the bases of the second and third metacarpals is significant as it helps in effectively controlling the movements of the wrist and stabilizing the forearm during various tasks, especially those requiring grip strength or precision. Understanding this muscle and its attachments is crucial for sports massage therapists, as they can address any issues related to wrist pain or injury through targeted massage techniques focusing on the forearm and hand.
