What is Maxilla?
[[file:Gray995.png|thumb]] The '''maxilla''' is the upper [[jaw]]. In [[mammal]]s it is tightly fused to the skull, but in [[fish]] and [[reptile]]s it is usually not. In [[snake]]s, for example, the maxilla is able to move relative to the rest of the [[skull]], and the jaws can separate entirely to swallow prey. {{biology-stub}} [[Category:Head (body part)]] [[Category:Bones of the skull]]
