Canine fossa

Canine Fossa

The Canine Fossa (pronounced: kəˈnaɪn ˈfɒsə) is a significant anatomical feature in the human skull.

Etymology

The term "Canine Fossa" is derived from the Latin words "caninus" meaning "of the dog" and "fossa" meaning "ditch or trench". The name is given due to its proximity to the canine tooth.

Definition

The Canine Fossa is a depression in the facial skeleton that is located on the frontal process of the maxilla, below the infraorbital rim and lateral to the nasal cavity. It is bordered by the canine ridge.

Function

The Canine Fossa serves as an attachment point for several muscles, including the Levator labii superioris and the Caninus muscle. It also provides space for the roots of the canine tooth and the premolar teeth.
