NSC Exam 1 questions with right actualanswers.
4 neuron functional zones ANS - input zone - dendrites
integration zone - axon hillock
conduction zone - axon
output zone - axon terminals
What kind of neurons make up most of the CNS? ANS - interneurons
astrocytoma ANS - tumor in brain or spinal cord - cancerous - astrocytes rapidly multiplying
Alexander disease ANS - genetic mutation causes astrocytes unable to get rid of GFAP (something they
produce) --> they fill up and die
Multiple sclerosis ANS - oligodendrocyte injury from autoimmune attack
Sympathetic nervous system ANS - fight or flight
parasympathetic nervous system ANS - rest and digest
white matter ANS - axon bundles - no neurons/cell bodies
gray matter ANS - clusters of neuron cell bodies
corpus callosum ANS - white matter
,basal ganglia ANS - Center of the brain - a bunch of neurons for movement
Parkinson's disease ANS - basal ganglia dies
limbic system ANS - emotional memory, regulation
cortex area ANS - consciousness, decision-making

Diffusion tensor imaging ANS - shows brain connections (images axons of neurons)
soma ANS - cell body
intrinsic proteins ANS - proteins on surface of cell membrane (receptors, channels, etc)
Kinesin transport type/direction ANS - anterograde transport (soma --> terminals)
Dynesin transport type/direction ANS - retrograde transport (terminals --> soma)
