The basilar artery, formed by the two vertebrals, 

 runs to the upper border of the pons, and divides into 

 the two posterior cerebrals. It gives off the following 

 branches : 



(a) Several transverse arteries on each side. One 

 the auditory, enters the internal meatus; another, the 

 anteroinferior cerebellar, to the anterior border of the 

 cerebellum.
