Flexor carpi radialis (Musculus flexor carpi radialis)
Educational content only — not medical advice.
Anatomy
A slanting superficial muscle from the medial epicondyle along the radial side of the forearm; its tendon passes in its own canal in front of the scaphoid to the second metacarpal base.
Origin & insertion
Medial epicondyle of the humerus via the common flexor tendon and antebrachial fascia.
Action
Flexes and radially deviates the wrist (its radial-deviation partner being the extensor carpi radialis longus).
Innervation
Median nerve (C6–C7).
Clinical notes
Its tendinopathy at the wrist base is the classic radial-sided wrist pain of keyboard users, tested by resisted flexion with radial deviation.
