Neuroanatomy exam questions based on Last's Anatomy 9th Edition.
| Front | Which of the following statements is FALSE? (p. 564-7)a. Trochlear nerve enters roof of the cavernous sinus where the free and attached margins of the tentorium cerebelli crossb. No nerves run within the medial wall of the cavernous sinus, which is mostly comprised of the endosteum on the sphenoid bodyc. Its contents include both those structures lying within its cavity (such as internal carotid artery and abducens nerve), as well as those embedded within its lateral wall (oculomotor nerve, trochlear nerve, three divisions of the trigeminal nerve)d. The inferiorly sloping oculomotor nerve crosses each of the three branches of the trigeminal nervee. None of the above |

| Front | All of the following statements regarding the trigeminal nuclei are false EXCEPT (p. 608, 631)a. Motor nucleus is positioned most laterally in cross-sections of the upper ponsb. Spinal nucleus is not seen in cross-sections of the upper ponsc. Mesencephalic nucleus is positioned medial to the motor nucleus in cross-sections of the upper ponsd. Abducens nucleus is intimately related to the spinal tract and nucleus of the trigeminal nerve, forming the trigeminal colliculus on the dorsal aspect of the lower ponse. Spinal nucleus is unique in that its cell bodies are those of first order neurons |

| Front | Which of the following statements regarding the retina is false? (p. 519-20)a. It is attached to the basal lamina of the choroidb. The inner surface of the retina is in contact with the vitreous bodyc. The light sensitive area ends abruptly at the ora serratad. The optic disc signifies the entrance of the optic nerve to the retina and it overlies lamina cribrosa of the sclerae. There are rods, but not cones, in the optic disc |
