Lateral view of the left infratemporal fossa, orbit, and middle cranial fossa. Also, the maxillary sinus has been exposed. The lateral and medial pterygoid muscles have been removed and a portion of the lateral pterygoid plate. This exposes the tensor veli palatini muscle descending toward the soft palate. Each division of the trigeminal nerve is observed arising from the trigeminal ganglion. (Image courtesy of AL Rhoton, Jr.)
