WITH CORRECT ANSWERS 2025/2026
1. perikaryon CORRECT ANSWER neuron cytoplasm, dense with nissel bodies,
also contain neurofibrils, bundles of neurofilaments, and neurotubules
2. axon terminals/synaptic knobs CORRECT ANSWER form synapses or junctions
with neurons or effector cells
3. axon CORRECT ANSWER conducting fiber, generate and conduct nerve impulses,
distal to cell body and begins from axon hillock
4. schwann cells CORRECT ANSWER make myelin in pns
5. myelin sheath CORRECT ANSWER insulating fatty layer that speeds transmission
6. cell bodies CORRECT ANSWER found in clusters
7. clusters of neuron cell bodies in the cns are called CORRECT ANSWER nuclei
8. clusters of neuron cell bodies in pns are called CORRECT ANSWER ganglia
9. neuroglia CORRECT ANSWER supporting cells for neurons
10. cns neuroglia CORRECT ANSWER astrocytes, oligodendrocytes, microglia,
ependymal cells
, 11. pns neuroglia CORRECT ANSWER Schwann cells and satellite cells
12. astrocytes CORRECT ANSWER form blood brain barrier, controlling the
chemical environment of the brain
13. ependymal cells CORRECT ANSWER secrete and monitor cerebrospinal fluid
14. microglia CORRECT ANSWER phagocytic cells, remove pathogens, waste, and
cellular debris
15. oligodendrocytes and schwann cells CORRECT ANSWER myelinate neurons,
wrapping them in fatty tissue
16. satellite cells CORRECT ANSWER regulate nutrients, gas, and neurotransmitter levels
17. nerves CORRECT ANSWER bundles of neuron fibers (axons) wrapped in
connective tissue coverings
18. most common neuron in the body CORRECT ANSWER multipolar neuron
19. multipolar neuron CORRECT ANSWER many branches, processes and extensions
off the cell body, most neurons in the cns and neurons that carry impulses away from
the cns are multipolar
20. dendrites CORRECT ANSWER receive incoming information and contain receptors
for neurotransmitters
