external definition

Skeletal and cartilage elements of the first pharyngeal arch.[TAO]

external ontology notes

in FMA, the jaw is an organism subdivision cluster, and includes mucosal tissue such as the gingiva as parts. It appears to be skeletal in MA (and has teeth as parts). It is reasonable to assume that ZFA and XAO consider the upper and lower jaws to be skeletal elements or clusters. EHDAA2 also considers these clusters. TODO - follow EHDAA2 model. These arbitrary differences in terminology and classification have to be reconciled with the genuine well-known biological differences in the skeletal elements across vertebrates
