The gelatinosa Rolandi {gliosa cornualis) of the dorsal horn is continued into the oblongata, but becomes insignificant, relatively, in the pars dorsalis pontis. The spinal root of the trigeminal nerve is in ectal relation with the gelatinosa Rolandi; at higher levels the spinal root of the vestibular nerve intervenes. FLOOR OF FOURTH VENTRICLE.
