  1. What does the anterior choroidal artery follow?The optic tract


  2. Cocaine as a local anestheticSTARTS in the frontal lobe, ENDS in the ventral horn of the spinal cord to interact with lower motor neurons that will innervate muscle, ROUTE: motor cortex layer 5 (pyramidal cell) -> corona radiata -> internal capsule -> crus cerebri (cerebral peduncles) -> pons -> pyramid -> decussation (cross over to the other side of the body) -> lateral corticospinal tract in spinal cord -> contralateral ventral horn. FUNCTION: activation of motor neurons in spinal cord


  3. QuantumConnects forebrain to spinal cord
    Brain stem= hypothalamus, thalamus, midbrain, hindbrain


  4. MOA of thioguanineinhibits PRPP amidotransferase -->inhibits purine synthesis
    *requires activation by HGPRT


  5. Schwann cellsmyelinate axons in the PNS, have phagocytic activity and clear cellular debris. Immature S-cells are generated from S-cell precursors that originate from neural crest
