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.
Answer:
The correct option is: b. trabeculae
Explanation:
Trabeculae are the tiny rod-like elements of the bone tissues that are responsible for supporting the framework of the various organs or parts of the body. It is generally made up of dense collagenous tissue and can also be composed of muscles and bones.
<u>The cancellous bone, also known as the spongy bone, is produced by the groupings of trabeculated bone tissues</u>.
