accessory nerve fiber bundle 
anterior spinocerebellar tract 
area postrema 
A small, rounded eminence on each side of the fourth ventricle, which receives nerve fibers from the solitary nucleus , spinal cord, and adjacent areas of the medulla. The area postrema lies outside the blood-brain barrier and its functions include acting as an emetic chemoreceptor.
