The muscles at the base of the thumb help move the thumb, and form a bulge in the hand called the thenar eminence. The muscles here are abductor pollicis brevis, flexor pollicis brevis and opponens pollicis. Adductor pollicis is nearby. Let's identify them and their movements, the bones they attach to and the nerves that innervate them. For fun.
