A manual of examinations : upon anatomy, physiology, surgery, practice of medicine, chemistry, obstetrics, materia medica, pharmacy and therapeutics, especially designed for students of medicine, to which is added a medical formulary . — On the middle line of tuber annu-lare, and extends from its posterior toits anterior margin, sending off branchesto the meatus auditorius internus, andthe labyrinth of the ear. Where is the arteria superior cere-belli?— Just behind the anterior edgeof the tuber annulare, until it gainsthe front margin of the cerebellum,and is there distributed. Where is the posterior artery of thecerebrum ? — One on each side, and isthe termination of the basilar. What is the circle called which en-closes the chiasm of the optic nervesand the corpora albicantia ? — Thecircle of Willis. CEREBRAL NERVES. FIRST PAIR. Where do the olfactory nerves arise ?(Fig. 95.) — From the corpora is their course and distribu-tion ?—They pass forward on each sideof the crista galli, reach the os setli-moides without anastomosing, and pass out of the cranium by a greatnumber of filaments, through the holes in the cribriform plate of thesethmoid bone, and ramify on the membrane lining the ANATOMY. 175 With what other nerves does it inosculate? — The ophthalmis andmaxillary. SECOND PAIR. Whence do the optic nerves arise ?^ — They arise from the thalaminervorum. What is their course and distribution ? — They pass outward andunite before the sella turcica, separate and leave the cranium throughthe optic foramen, and pass to enter the globe of the eye. THIRD PAIR. Whence do the third pair arise ? ^ (Figs. 95, 96,97.)—The third pair,or motores oculorum, arise from the crura cerebri, just before the an-terior edge of the pons varolii. Fig. 96.
