Winding around the inferior cerebellar peduncle in the lower part of the fourth ventricle, and crossing the area acustica and the medial eminence are a number of white strands, the medullary striae, which form a portion of the cochlear division of the vestibulocochlear nerve and disappear into the median sulcus. Stria medullaris are axons of arcuate neurons.
The medullary striae, which run alongside the inferior cerebellar peduncle in the lower part of the fourth ventricle and cross through the area acustica and medial eminence, are white strands that contribute to the cochlear division of the vestibulocochlear nerve. These striae consist of axons from arcuate neurons.
