The term 'armbones' is a collective term for the four bones of the forearm: the ulnas (5 letters), ulne (4 letters), RADII (5 letters), and ulnae (5 letters). The ulna and radius are the two long bones of the forearm, located on either side of the arm. The ulna is the larger of the two bones and is located on the medial side of the arm, while the radius is located on the lateral side. The ulnae and ulnas are the two short bones of the forearm, located at the elbow joint. The ulnae is the larger of the two bones and is located on the medial side of the elbow, while the ulnas is located on the lateral side. Together, these four bones form the armbones, which are essential for movement and stability of the forearm.
