5) pretty well tolerated...mostly just the hema tox.

- < 5 cells/mm^3, 35mg/dL of protein and 60mg/dL of glucose
- a protein secreted by fat cells, when abundant causes the brain to increase metabolism and decreases hunger.
- has 5 subunits - 2abgd = fetal, 2abed = adult; adult permit larger currents but have more frequent opening times with shorter mean open time - better suited to fast activation of skeletal muscles
- No, even very small infarcts can produce severe neurological deficits depending of location

5 True/False questions
What does the anterior choroidal artery follow? → The optic tract
Cocaine as a local anesthetic → STARTS 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
Quantum → Connects forebrain to spinal cord
Brain stem= hypothalamus, thalamus, midbrain, hindbrain
MOA of thioguanine → inhibits PRPP amidotransferase -->inhibits purine synthesis
*requires activation by HGPRT
Schwann cells → myelinate 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
