2. INFRATEMPORAL FOSSA
 THE INFRATEMPORAL FOSSA IS THE SPACE
BENEATH THE BASE OF THE SKULL, BETWEEN
THE SIDE WALL OF THE PHARYNX AND RAMUS
OF THE MANDIBLE.

3. INFRATEMPORAL FOSSA
 COMMUNICATES WITH THE TEMPORAL FOSSA
THROUGH A GAP DEEP TO THE ZYGOMATIC
ARCH.

4. INFRATEMPORAL FOSSA
 ALSO REFERRED TO AS THE PARAPHARYNGEAL
SPACE OR LATERAL PHARYNGEAL SPACE.

7. ROOF
 FORMED BY THE INFRATEMPORAL SURFACE OF
THE GREATER WING OF THE SPHENOID.
 IT IS PIERCED BY FORAMEN SPINOSUM AND
FORAMEN OVALE.

8. MEDIAL WALL
 FORMED BY LATERAL SURFACE OF THE LATERAL
PTERYGOID PLATE OF THE SPHENOID.
 IT IS SEPARATED FROM THE ANTERIOR WALL BY
PTERYGOMAXILLARY FISSURE.

9. LATERAL WALL
 FORMED BY THE RAMUS OF THE MANDIBLE.

10. ANTERIOR WALL
 FORMED BY THE INFRATEMPORAL SURFACE OF
THE MAXILLA.
 IT IS SEPARATED FROM ROOF BY INFERIOR
ORBITAL FISSURE.

11. FLOOR
 OPEN AND EXTENDS UP TO THE LEVEL OF THE
BASE OF THE MANDIBLE.

12. POSTERIOR WALL
 FORMED BY STYLOID PROCESS OF THE
