Q

What is the Roof, Anterior, Medial, Posterior , inferior,boundary

A

Superior BorderRoof- a) Greater Wing of the Sphenoid Bone b) Temporal Bone (roof)

INferior- no floor, trap you form getting to mandlble but no boundary

Anterior Boundary- Maxillae

Medial Boundary -
a)Pterygoid plate Pterygoid muscle (attaches to insdie of mandible_/ b)PHARNYNX- PHARYNGEAL TUBERCLE (attachent of pharynx

Lateral boundary -Mandible?

Posterior boundary- not much barrier,
