Answer:
1. dendrite = directs impulses toward the soma.
2. axon = conducts impulses toward the synaptic terminal.
3. perikaryon = region surrounding nucleus.
4. collateral branches = main branches of an axon.
5. synaptic terminal = enlarged end of an axon.
6. synaptic vesicles = contains neurotransmitters.
7. axon hillock = connects the cell body and axon.
8. Nissl bodies = clusters of RER and free ribosomes.
9. telodendria = fine branches of an axon.
10. myelinated internode = part of axon covered by Schwann cell.
11. neurilemma = Schwann cell's plasma membrane.
12. axolemma = membrane of the axon.
13. astrocyte = Forms the blood-brain barrier.
14. cell body = soma.
The missing parts in the question refer to the various parts of a typical neuron.
- The dendrite directs electrical impulses toward the soma.
- The Axon conducts impulses towards the synaptic terminal.
- The perikaryon is the region surrounding the nucleus.
- The synaptic terminal is the enlarged end of an axon.
- The synaptic vesicles contain neurotransmitters.
- The Nissl bodies contain clusters of Rough Endoplasmic Reticulum (RER) and free ribosomes.
- The cell body is another term for the soma of a neuron.
- The Axolemma is the membrane of the axon.
- The endothelial cell is a cell that forms the blood-brain barrier.
- The Telodendria is a fine branch of the axon.
