Maxilla: meaning, definitions and examples

anatomy part

The maxilla refers to the upper jawbone in vertebrates. In humans, it forms the central part of the face and plays a critical role in the structure of the oral cavity. The maxilla supports the upper teeth and contains the maxillary sinuses, which are air-filled spaces that help lighten the skull. It also articulates with several other bones in the skull, contributing to facial structure and function. The maxilla is essential for functions such as chewing, speaking, and forming facial expressions.
