The top jaw is called the maxilla.
The maxilla, or upper jawbone, is a crucial facial bone that plays several important roles. It's not just one bone, but rather a pair of bones that fuse together at the midline of the face.
Here's a breakdown of its key functions and characteristics:
-
Holds the upper teeth: The maxilla contains sockets (alveoli) that house the upper teeth, providing them with structural support.
-
Forms the midface: It significantly contributes to the shape and structure of the midface region, including the cheekbones and the area around the nose.
-
Supports the nose: The maxilla provides support for the base of the nose.
-
Forms part of the orbital cavity: It contributes to the formation of the eye socket (orbit).
-
Contains the maxillary sinus: Inside the maxilla is a large air-filled space called the maxillary sinus.
Essentially, the maxilla is a foundational bone in the facial structure, vital for both function (chewing, speech) and aesthetics. Understanding its role helps in comprehending facial anatomy and related medical conditions.
