Maxillary

From WikiMD's Wellnesspedia

Maxillary refers to the structures related to the maxilla, one of the two upper jawbones forming the roof of the mouth and the floor of the nose. The maxilla is a vital part of the skull and plays a significant role in facial structure and appearance. It also plays a crucial role in functions such as eating, speaking, and breathing.

Anatomy[edit | edit source]

The maxilla is a paired bone with left and right halves, which are fused at the midline. It consists of a body and four processes: the zygomatic process, the frontal process, the alveolar process, and the palatine process. The body of the maxilla houses the maxillary sinus, one of the four pairs of paranasal sinuses.

Functions[edit | edit source]

The maxilla plays a crucial role in several functions:

  • Facial Structure: The maxilla helps shape the middle third of the face. It provides support for the nose and forms the floor of the orbit (eye socket).
  • Eating and Speaking: The maxilla houses the upper teeth and is involved in the process of mastication (chewing). It also contributes to the formation of the oral cavity, which is essential for speech production.
  • Breathing: The maxillary sinus, housed within the body of the maxilla, is involved in warming and humidifying inhaled air.

Clinical Significance[edit | edit source]

Conditions affecting the maxilla can have significant impacts on appearance, function, and overall health. These include:
