Final answer:
A client's facial shape is determined by the position and prominence of the facial bones, which include the maxillae and mandible among other bones that form the face.
Step-by-step explanation:
The client's facial shape is determined by the position and prominence of the facial bones. The skull is a part of the human skeleton that provides a bony framework for the head and includes bones of the cranium and face. The 14 facial bones of the skull are essential for forming the face and provide cavities for the eyes, nose, and mouth. Large bones in the face such as the maxillae and mandible influence the overall structure and appearance of one's face.
