FIG. 142. \t,\lKAL SURFACE OF BRAIN STEM, PAPIO C^â ^OCEPHALUS. [Actual Length 46 mm.] Key to Diagram, cer. i'ed., Cerebral Peduncle; pvr. dec, Pyramidal Decussation; trap, body, Trane- zoid Body. inferior oIi\e points to an expansion m the rellex control ol simultaneous move- ments of eyes, head and hands as well as in all skilled, learned performances. The Pons Varolii. On the ventral surface of the oblongata, at its cephahc extremity, there appears the usual expansion of the neuraxis, the pons Varolii. A sharp line of demarcation separates the oblongata from the pons, the bulbopontile sulcus. A small blind recess at the point where the ventromedian sulcus meets the bulbopontile sulcus, forms the foramen caecum posticum. From the sulcus between the inferior olive and the pyra- mid, libers of the twelfth nerve emerge from the oblongata. At the cephalic extremity of the pons is the t)ptico-peduncular space bounded in Iront by.
