Carn Ap Licensure Questions with VERIFIED Answers (Guaranteed
Success)
Q1: oligodendrocytes.
Answer: form myelin sheaths in CNS
Q2: microglia.
Answer: phagocytic immune cells
Q3: ependymal cells.
Answer: line cavities of CNS produce and circulate cerebrospinal fluid
Q4: satellite cells.
Answer: in ganglia support and regulate chemical environment in PNS
Q5: schwann cells.
Answer: form myelin sheath in PNS
Q6: Nissl substance.
Answer: RER found in cell body and dendrites, but not axon of neurons.
Q7: depolarization.
Answer: starts by opening of voltage gated NA channels membrane potential moves from -70 to +30
Q8: Repolarization.
Answer: Na channels close and K channels open to let K exit the cell so that the loss of positive ions
returns membrane potential to -70mV
Q9: hyperpolarization.
Answer: K channels close and membrane potential goes to -80
Q10: Return to Resting Potential.
Answer: Na/K pump restores ions to -70
, Q11: when the membrane cannot respond to new stimulus happens from depol to repol
Answer: refractory period.
Q12: continuous propagation.
Answer: happens in unmyelinated axon
Q13: saltatory propagation.
Answer: happens in myelinated axons
Q14: chemical synapses.
Answer: release neurotransmitters that are stored in synaptic vesicles (usually bind to ligand-gated ion
channels)
Q15: chemical synapses have a.
Answer: synaptic delay
Q16: removal of nts.
Answer: simple diffusion enzymatic degradation uptake by cells (presynaptic neurons or glial cells)
Q17: simple series circuits (rare).
Answer: one presynaptic neuron with one postsynaptic neuron
Q18: complex series circuits.
Answer: divergent: 1 pre stimulates multiple post (amplify sign) convergent: multiple pre stimulates
one post (allows inhibition) common in CNS reverberating: feedback loops, breathing, sleep wake,
parallel after discharge: differing synapses which can prolong the stimulus (chemical synapses) (light
turning off)
Q19: electrical synapse connection type.
Answer: gap junctions (connexions)
Q20: brain 4 major sections.
Answer: cerebral hemisphere diencephalon cerebellum brainstem
