What is the maxilla on skull?
The maxilla has a complex shape and consists of several anatomical features, including:
- The body: the main portion of the maxilla that forms the upper jaw.
- The alveolar process: a ridge on the maxilla that contains the sockets for the upper teeth.
- The palatine process: a horizontal plate that forms the floor of the nasal cavity and the roof of the mouth.
- The zygomatic process: a projection that articulates with the zygomatic bone to form the lateral wall of the orbit.
- The frontal process: a projection that articulates with the frontal bone to form the bridge of the nose.
- The maxillary sinus: a hollow space within the maxilla that is lined with mucous membrane.
The maxilla plays several important roles in the skull, including:
- Forming the upper jaw and providing support for the teeth.
- Contributing to the shape and structure of the face.
- Providing a passageway for the nasal passages and sinuses.
- Participating in the formation of the orbits.
- Providing attachment points for muscles involved in facial expression, chewing, and swallowing.
