What are the upper jawbones known as?

Mandible
Mastoid
Zygoma
Maxillae

The correct answer is: Maxillae

The upper jawbones are known as the maxillae. These bones form the upper jaw and play a crucial role in supporting the teeth, forming part of the facial skeleton, and contributing to the structure of the mouth, nasal cavity, and eye sockets. Each maxilla (singular) contains important anatomical features such as the alveolar process, which holds the upper teeth, and the maxillary sinuses, which are air-filled spaces that help lighten the skull and improve vocal resonance. The maxilla also connects with several other bones of the skull, including the nasal bones and the zygomatic bones, forming a stable structure that is essential for functions like chewing and speaking. Understanding the anatomy and function of the maxillae is important for anyone training in emergency medical services, as knowledge of facial structure can assist in identifying injuries or conducting assessments during trauma situations.
