Maxillary bone
Maxillary Bone
The Maxillary Bone (pronounced: măk′sĭ-lĕr′ē bōn), also known as the Maxilla, is one of the two upper jawbones that form the upper jaw and hard palate in the human skull. The term "Maxillary" is derived from the Latin word "Maxilla" which means "jawbone".
Structure
The Maxillary Bone is a paired structure, with each side contributing to the formation of the upper jaw, the roof of the mouth (Palate), the sides of the nasal cavity, and the floor of the eye socket (Orbit). It is composed of a body and four processes: the zygomatic, frontal, alveolar, and palatine.
Function
The Maxillary Bone plays a crucial role in facial structure and function. It houses the upper teeth (Dentition) and forms part of the nasal cavity and eye socket. It also plays a significant role in the process of mastication (chewing) and speech.
