The term ptérygoïde, derived from the Greek word pterygoeides meaning "wing-shaped," refers to a bony process or structure found in the anatomy of certain vertebrates, particularly within the skull. Most notably, the pterygoid bones are a pair of bones located in the posterior part of the palate, forming a significant portion of the roof of the mouth and contributing to the base of the skull. In humans, the pterygoid processes project downwards from the sphenoid bone.
These pterygoid structures serve several important anatomical and functional roles. They provide attachments for muscles involved
In non-mammalian vertebrates, the arrangement and prominence of pterygoid bones can vary considerably. For example, in
