Question

Which cranial nerve pair has two sensory branches which both pass through the internal acoustic meatus?

Answer 1

VIII cranial nerve pair has two sensory branches which both pass through the internal acoustic meatus.

A unique somatic afferent nerve is cranial nerve VIII. The vestibular nerve and the cochlear nerve make up its two components. Hearing is made possible by the cochlear portion, while balance and movement are mediated by the vestibular portion.

Both pieces come together to form the vestibulocochlear nerve, which exits the body of the skull through the internal acoustic meatus. Therefore, The auditory vestibular nerve, sometimes referred to as the vestibulocochlear nerve or CN VIII, is a cranial nerve that travels from the inner ear to the brain carrying information about balance and sound.

Therefore, VIII cranial nerve pair has two sensory branches which both pass through the internal acoustic meatus.
