CBIS CHAPTER 3 QUESTIONS AND ANSWERS | CBIS CHAPTER 3 STUDY GUIDE
2026
Neuroplasticity - correct answer ✔✔ability of nervous system/brain to form new connections
and create new neurons
Experience-dependent learning - correct answer ✔✔experiences change, which changes brain
structure
Behavior leads to synaptic changes which lead to motor map reorganization
Impact of greater numbers of synapses within a grouping of neurons - correct answer ✔✔better
speed and efficiency in neuron communication
-axon sprouting and synaptogenesis
Steps of secondary cascade- neurodegeneration (pathophysiological process) - correct answer
✔✔Secondary injury
Pathophysiological processes: impaired blood flow, tissue damage, edema formation,
inflammation, axon terminal depolarization, intracellular breakdown, apoptosis --> cell death
Neuroprotective agents (currently being studied) - correct answer ✔✔1) magnesium
2) nicotinamide
3) progesterone
Axon sprouting & synaptogenesis - correct answer ✔✔when neural projections to a brain region
are lost, remaining cones sprout and form new synaptic connections onto partially denervated
ones
Steps of secondary injury cascade (delayed non-mechanical processes) - correct answer
✔✔Delayed non-mechanical processes: metabolic imbalance, membrane permeability, blood
