Question

Name 6 structures that the maxillary bone either contains or forms. It contains 4 structures and forms part of 2 different structures.

Be sure to indicate which structures it forms and which ones it contains.

Answer 1

The maxillary bone contains the upper teeth in the alveolar process, the infraorbital foramen, and forms the anterior portion of the hard palate and helps form the lateral floor and medial floor of the orbit, and lateral base of the nose.

Step-by-step explanation:

Structures of the Maxillary Bone

The maxillary bone, also known as the maxilla, performs several critical functions as part of the facial skeleton. Here are six structures that the maxillary bone either contains or forms:

• Alveolar process: Contains the sockets (alveoli) for the upper teeth.
• Infraorbital foramen: Contains the exit point for the infraorbital nerve supplying sensation to the mid-facial region.
• Anterior three-quarters of the hard palate: Formed by the palatine process of each maxilla, creating the bony plate that separates the oral and nasal cavities.
• Lateral floor of the orbit: Each maxilla contributes to the formation of this structure, supporting the eye.
• The medial floor of the orbit: Part of the orbit structure formed by the maxilla.
• Lateral base of the nose: The maxilla contributes to this facial feature as part of its structure.

These structures highlight the diverse role of the maxillary bone in forming the upper jaw, supporting teeth, and contributing to the orbits and the nose.
