The presence of the pyramids thus gives rise to three sets of fibers the ventral or superficial, the dorsal or deep, and the middle or penetrating. Interspersed in the gray matter occupying the interstices of the ventral portion of the pons small multipolar cells are found. The dorsal portion of the pons consists largely of gray matter which is continued up from below, especially the formatio reticular is and the dorsal tracts of gray substance. In places the gray matter is grouped to form the nuclei of the fifth, sixth, seventh, and eighth nerves.
