Which bones make up the upper jaw?

1. Mandibles

2. Maxillae

3. Temporal bones

4. Palatinates

The correct answer is: Maxillae

The upper jaw is primarily formed by the maxillae, which are two facial bones that fuse together to create the central part of the face, holding the upper teeth and forming the boundaries of the nasal cavity and orbits for the eyes. The maxillae also play a crucial role in supporting the structure of the face and facilitating functions like chewing and speaking. In contrast, the mandibles constitute the lower jaw; they do not form part of the upper jaw structure. Temporal bones are located on the sides and base of the skull and are involved in protecting the brain and forming the sides of the head but do not contribute to the structure of the jaw. The palatine bones are also facial bones, but they are located further back in the mouth and do not form the primary structure of the upper jaw.
