Final answer:
The internal acoustic meatus, located on the medial wall of the petrous ridge in the posterior cranial fossa, allows passage of the vestibulocochlear nerve and the facial nerve.
Step-by-step explanation:
The two nerves that pass through the internal acoustic meatus, located on the medial wall of the petrous ridge in the posterior cranial fossa, are crucial to our senses of hearing and balance. The first is the vestibulocochlear nerve (CN VIII), which carries both equilibrium and auditory sensations from the inner ear to the brain. It is comprised of two separate divisions: one associated with balance (the vestibular nerve) and one related to hearing (the cochlear nerve).
The second nerve is the facial nerve, which controls the muscles of the face and some functions of taste and salivation. While the facial nerve also passes through the internal acoustic meatus, it is important not to confuse it with the external auditory meatus, which pertains to the outer ear and does not have these cranial nerves passing through it.
