Serial transverse sections of the brain stem
Medulla oblongata.
A slice of tissue 3.5 mm. thick has been removed to expose this surface, cut through the rostral part of the inferior olive. The restiform bodies continue to increase in size as they ascend toward the cerebellum. The lateral recesses of the ventricle extend around the restiform bodies, and the tela chorioidea and roots of the ninth and tenth nerves lie in close relationship here. The cochlear nuclei are visible within the lateral recess on the right and on the cut surface at (18). The sulcus limitans forms a groove in the floor of the ventricle medial to the area acustica (3).
