<P> The hypoglossal nerve arises as a number of small rootlets from the front of the medulla , the bottom part of the brainstem , in the preolivary sulcus , which separates the olive and the pyramid . The nerve passes through the subarachnoid space and pierces the dura mater near the hypoglossal canal , an opening in the occipital bone of the skull . </P>
