The |flexor carpi ulnaris| is used to bend the hand at the wrist. It gets its name from carpus (wrist bone) and the |ulna| (forearm bone). This muscle has two heads, one arises from the |humerus| (upper arm bone) and the other arises from the |ulna|. The two heads combine to form a single, flat belly that tapers into a long ~tendon~ inserting in the |pisiform bone| of the wrist.
