Outrageously Funny Word Dictionary :: Collarbones

👉 In anatomy and physiology, a collarbone is a long bone located at the end of the spine. It consists of two short bones - one called the humerus, which connects the shoulder joint to the upper arm, and another called the ulna, which connects the elbow joint to the wrist. Collars are also present in some animals, including horses and cows, where they function as a protective mechanism for the neck.
