The pterygoid plate is a bony structure located in the skull, specifically part of the sphenoid bone. It consists of two plates: the medial and lateral pterygoid plates. These plates serve as attachment points for various muscles involved in jaw movement, particularly the muscles responsible for chewing. The pterygoid plates are situated behind the upper jaw and contribute to the formation of the pterygopalatine fossa, a space that houses important nerves and blood vessels. Understanding the anatomy of the pterygoid plates is essential for dental and medical professionals when addressing issues related to the jaw and facial structure.
