what passes through the caecum foramen
emissary veins
what passes through the stylomastoid foramen
CNVII (facial)
what is the pathway of the facial nerve
arises from the cerebellopontine angle
enters the internal acoustic meatus, passes through the facial canal and exits via the stylomastoid foramen.
it reaches the parotid gland and divides into 5: the temporal, zygomatic, buccal, marginal mandibular and cervical branches
