auditory meatus in company with the 7th, which passes into the 

 aqueduct of Fallopius. The Sth divides into two branches, one for 

 the cochlea, the other for the vestibule and semicircular canals. The 

 filaments of the latter branch penetrate the minute foramina seen 

 at the bottom of the internal auditory meatus, and are finally 

 distributed in the saccule, utricle, and ampullated ends of the 

 membranous semicircular canals. The cochlear branch penetrates 

 the modiolus, and in its passage detaches twigs which pass outwards 

 in the osseous spiral lamina to reach the basilar membrane. Within 

 the spiral lamina there are numerous ganglion cells placed on the 

 course of the nerve fibres.
