maxilláris

Maxilláris (Latin: maxillaris; "of the maxilla") is an anatomical adjective used to denote structures related to the maxilla, the paired upper jaw bone of the skull. The word derives from the Latin maxilla (jawbone) with the suffix -aris, yielding "maxillaris" meaning "of the maxilla." In contemporary medical terminology, maxillaris is most commonly encountered in Latinized names of anatomical structures.

In human anatomy, several widely used terms employ the adjective maxillaris. Nervus maxillaris, the maxillary nerve, is the second division of the trigeminal nerve (CN V2) and provides sensation to the midface. Arteria maxillaris, the maxillary artery, is a major vessel supplying deep face structures, with branches to the teeth, palatal mucosa, and nasal cavity. Sinus maxillaris, the maxillary sinus, is the largest of the paranasal sinuses and lies within the maxilla, adjacent to the nasal cavity and orbit.

The term is mostly encountered in Latin or in contexts using Latin nomenclature; in English, the corresponding adjective is maxillary. Beyond clinical anatomy, maxillaris may appear in taxonomic or descriptive phrases to indicate relation to the maxilla in various species, though such usage is less standardized.
