Palmar flexion is one of the movements of the wrist and hand which takes place at the wrist joint, where the angle between the palm and the forearm is decreased. In this context, this consists of bending the hand towards the inside of the wrist, an action known as flexion in anatomical terms. The opposite of this is dorsiflexion or extension; in the case of palmar extension, the angle between the back (dorsum) of hand and the forearm is reduced - specifically, the hand bends away from the inside of the wrist.
