Where are the adductor and opponens pollicis located on the thumb?
More specifically: The adductor pollicis fastens medially at your 3rd metacarpal bone and laterally at the proximal phalanx of your thumb. The opponens pollicis runs from the flexor retinaculum and the trapezium bone to the metacarpal bone of the thumb. The Xs in the picture display common areas where trigger points often get activated.
