๐ What Does โJawโ Mean?
The jaw refers to the bone that forms the lower part of the face and holds the lower teeth.
In anatomy, itโs known as the mandible, while the upper jaw is called the maxilla. The word comes from Old English ceowan, meaning โto chew,โ which perfectly describes its function.
In medicine and dentistry, the term appears frequently when describing facial structure, injury, or movement.
๐ Clinical Usage
In clinical communication, jaw is used to describe both anatomical structure and functional movement.
Youโll find it mentioned in nursing notes, radiology reports, and oral surgery records โ often when referring to pain, swelling, or limited motion in the temporomandibular joint (TMJ).
Healthcare professionals may document observations like:
- โJaw tenderness noted over the right TMJ.โ
- โLimited jaw opening due to pain.โ
- โJaw deviation observed on mouth opening.โ
