Ulnae is a medical term used to describe the pair of long bones located in the forearm, which connect the wrist to the elbow. These bones are also commonly referred to as the forearm bones. However, there are other synonyms for the word ulnae, such as the cubitus bone, which is derived from the Latin word for elbow. Another term used for the ulnae is the elbow bone, which refers to the bony protrusion located at the end of the ulnar bone. Additionally, some people may refer to the ulnae as the lower arm bones or the second arm bones, as they are positioned closer to the hand than the upper arm bone.
