    1. ANAT 321 REVIEW LABORATORY 1 NEUROANATOMY LAB
    2. BRAINSTEM VENTRAL VIEW MIDBRAIN medulla pons midbrain
    3. BRAINSTEM VENTRAL VIEW MIDBRAIN medulla pons midbrain Cerebral peduncle CN 3 CN 5 CN 6 Pyramid CN 9 CN 8 CN 7 CN 10 Inferior olive
    4. REVIEW: LAB 1 <ul><li>Question </li></ul><ul><ul><li>What structure lies lateral to the pyramids? </li></ul></ul><ul><li>Answer </li></ul><ul><ul><li>The inferior olive </li></ul></ul>
    5. REVIEW: LAB 1 <ul><li>Question </li></ul><ul><ul><li>What cranial nerve exits ventrally between the cerebral peduncles? </li></ul></ul><ul><li>Answer </li></ul><ul><ul><li>Cranial nerve 3 </li></ul></ul>
    6. BRAINSTEM DORSAL VIEW w / out cerebellum
    7. BRAINSTEM DORSAL VIEW w / out cerebellum Superior colliculus Middle cerebellar peduncle Inferior cerebellar peduncle Nucleus gracilis Nucleus cuneatus 4 th ventricle inferior colliculus
    8. REVIEW: LAB 1 <ul><li>Question </li></ul><ul><ul><li>Which cranial nerve lies between the pyramids and the inferior olives? </li></ul></ul><ul><li>Answer </li></ul><ul><ul><li>CN 12 </li></ul></ul>
    9. REVIEW: LAB 1 <ul><li>Question </li></ul><ul><ul><li>What is the relationship between the cerebral peduncles and the pyramids? </li></ul></ul><ul><li>Answer </li></ul><ul><ul><li>The pyramids comprise the corticospinal fibres which are a white matter fibre pathway originating in the motor cortices. The fibres course through the internal capsule and then funnel down into the cerebral peduncles and then through the medulla. </li></ul></ul>
    10. REVIEW: LAB 1 <ul><li>Question </li></ul><ul><ul><li>Why are the cerebral peduncles larger than the pyramids? </li></ul></ul><ul><li>Answer </li></ul><ul><ul><li>There are more fibre tracts in the cerebral peduncles </li></ul></ul>
    11. REVIEW: LAB1 <ul><li>Be sure that you understand the structure of the ventricular system in the medulla, pons, & midbrain </li></ul><ul><li>Answer </li></ul><ul><ul><li>Ventricles are spaces in the brain filled with cerebral spinal fluid (CSF) </li></ul></ul>
    12. REVIEW: LAB 1 <ul><ul><li>Ventricles are spaces in the brain filled with cerebral spinal fluid (CSF) </li></ul></ul>anterior posterior
    13. REVIEW: LAB 1 <ul><li>There are two lateral ventricles found in both cerebral hemispheres </li></ul>Lateral ventricles
    14. REVIEW: LAB 1 <ul><li>The walls of the third ventricle are formed by the thalamus </li></ul>
    15. REVIEW: LAB 1 <ul><li>CSF flows from the third ventricle through the midbrain to the fourth ventricle by the cerebral aqueduct </li></ul>
    16. REVIEW: LAB 1 <ul><li>The fourth ventricle is located dorsal to the pons and medulla </li></ul>
    17. REVIEW: LAB 1 <ul><li>Be sure that you understand the relationship of the cerebellum to the 4th ventricle and to the medulla and pons. </li></ul><ul><li>Answer </li></ul><ul><ul><li>The cerebellum forms the roof of the 4th ventricle </li></ul></ul>
    18. REVIEW: LAB 1 <ul><li>Be sure that you understand the relationship of the cerebellum to the 4th ventricle and to the medulla and pons. </li></ul><ul><li>Answer </li></ul><ul><ul><li>The cerebellum is attached to the pons through the middle cerebellar peduncles and the medulla by the inferior cerebellar peduncles </li></ul></ul>
