NSC FINAL EXAMINATION UPDATED 2025 WITH
QUESTIONS AND MOST CORRECT ANSWERS GUARANTEED
A+
4 neuron functional zones VERIFIED ANSWERinput zone - dendrites
integration zone - axon hillock
conduction zone - axon
output zone - axon terminals
What kind of neurons make up most of the CNS? VERIFIED
ANSWERinterneurons
astrocytoma VERIFIED ANSWERtumor in brain or spinal cord -
cancerous - astrocytes rapidly multiplying
Alexander disease VERIFIED ANSWERgenetic mutation causes
astrocytes unable to get rid of GFAP (something they produce) --> they
fill up and die

bodies
gray matter VERIFIED ANSWERclusters of neuron cell bodies
corpus callosum VERIFIED ANSWERwhite matter
basal ganglia VERIFIED ANSWERCenter of the brain - a bunch of
neurons for movement
Parkinson's disease VERIFIED ANSWERbasal ganglia dies
limbic system VERIFIED ANSWERemotional memory, regulation
