Skull bones

facial bone

bones situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum

bone in the human skull which, when joined together, forms the sides and roof of the cranium

saucer-shaped membrane bone situated at the back and lower part of the cranium

The premaxilla (or praemaxilla) is one of a pair of small cranial bones at the very tip of the upper jaw of many animals, usually, but not always, bearing teeth. In humans, they are fused with the maxilla. The "premaxilla" of therian mammals has been usually termed as the incisive bone. Other terms used for this structure include premaxillary bone or os premaxillare, intermaxillary bone or os intermaxillare, and '''Goethe's bone'''.

Usually in the back of the jaw, on the upper edge, it is connected to all other jaw bones: dentary, angular, splenial and articular. It is often a muscle attachment site. It has been noted in dinosaurs.

The splenial and coronoid are together known as the paradental elements. In non-tetrapod vertebrates, the splenial is known as the first infradentary and forms part of the infradentary series along with the p
