ulnae
Noun (plural of ulna): The ulnae are the two long bones in the forearm, located on the side opposite the thumb (the medial side when in the standard anatomical position). In humans, each ulna runs parallel to the radius and articulates with the humerus at the elbow and with the carpal bones at the wrist.
