This model shows the facial nerve exiting the stylo-mastoid foramen entering the parotid gland, the carotid artery and the petrus ridge with the entry of the facial nerve in the internal auditory meatus

This model shows "Z" shape of the facial nerve as it changes five times in its course from the brain stem to the stylomastoid foramen.
