The term 'foreleg parts' refers to the bones of the forelegs of animals, which are typically the humerus, radius, and ulnae. The ulnae, which is a five-letter word, is one of the two bones in the lower arm, located on the medial side of the forearm. It is the larger of the two bones and is connected to the humerus at the elbow joint. The ulnae is also connected to the radius, which is the smaller bone located on the lateral side of the forearm. Together, the ulnae and radius form the elbow joint.
