Virginia Permanent Makeup (PMU) State Board Practice Exam

The bone that forms the upper jaw is the maxilla. The maxilla is a key facial bone that supports the upper teeth and also contributes to the formation of the orbit (eye socket) and the nasal cavity. Its importance lies in its role in facilitating functions such as chewing and speaking, as well as forming the roof of the mouth.

In contrast, the mandible is the lower jaw bone and is responsible for holding the lower teeth in place. The nasal bone forms part of the bridge of the nose but does not contribute to the jaw structure. The temporal bone, located at the sides and base of the skull, is involved in housing structures of the ear and is not related to the jawline. Understanding the anatomical contributions of the maxilla enhances knowledge of facial structure and function, which is crucial for practices related to permanent makeup and facial aesthetics.
