BIOL 2457 LAB PRACTICAL 3 UTA QUESTIONS
WITH CORRECT ANSWERS 2026/2027
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
