Anatomy Quiz: Pterygopalatine and Infratemporal Fossa

An irregular cavity located below and medial to the Zygomatic arch, defined by several borders.

Superior: greater wing of sphenoid; Inferior: medial Pterygoid muscle; Anterior: maxilla; Posterior: styloid and condylar processes; Medial: sphenoid and palatine bones; Lateral: ramus and coronoid process of mandible.

Muscles located in the Infratemporal Fossa, including the lateral Pterygoid, medial Pterygoid, masseter, and temporalis muscles.

Structures that pass through the Infratemporal Fossa like the inferior alveolar nerves, maxillary artery/vein, sensory branches of the trigeminal nerve, and middle meningeal vein.

Understanding the Infratemporal Fossa is vital for clinicians due to its containing structures that can be affected during procedures.

A space between the infratemporal fossa and the nasopharynx, shaped like an inverted pyramid.

Formed by maxilla, palatine, and sphenoid bones with specific anterior, posterior, medial, lateral, and inferior walls.

Contains neurovascular structures like maxillary nerve, pterygopalatine ganglion, and maxillary artery.

Seven openings connecting the fossa with orbit, nasal, oral cavity, and more.

Inverted pyramidal shape allowing for specific arrangements of structures.

The skull that protects the brain and supports facial structure.

A fibrous joint that connects cranial bones.

Bones that form the cranium, including frontal and parietal bones.

The bone forming the forehead and part of the eye sockets.

Bones located on the sides and top of the cranium.

A light, spongy bone that forms part of the nasal cavity and orbits.
