[edit] Tributaries received
It receives tributaries corresponding with the branches of the maxillary artery.
Thus it receives the following veins:
- sphenopalatine
- middle meningeal[1]
- deep temporal
- pterygoid
- masseteric
- buccinator
- alveolar
- some palatine veins
- a branch which communicates with the ophthalmic vein through the inferior orbital fissure
[edit] Relations
This plexus communicates freely with the anterior facial vein; it also communicates with the cavernous sinus, by branches through the foramen Vesalii, foramen ovale, and foramen lacerum.
