Origin and Insertion of Flexor Carpi Radialis
- Origin-Medial epicondyle of the humerus (common flexor tendon)
- Insertion-base of the second and third metacarpal on the anterior side
-
Action, R/NR and D/S of Flexor Carpi Radialis
- Flexes wrist
- Abducts wrist (radial deviation)
- May assist with flexing the forearm at the elbow
- R and S
-
How to find the Palmaris Longus
Bring fingers together and contract (make the sign of the beast)
