What is the maxilla on skull?

The maxilla, also known as the upper jawbone, is one of the paired bones that form the midface. It is located below the eye sockets and above the mouth, and it articulates with several other bones, including the frontal bone, ethmoid bone, zygomatic bone, and palatine bone.

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.
