Question

The ______ conducts impulses toward the soma. The______ conducts impulses toward the synaptic terminals. The ______ is the region surrounding the nucleus. The ______ is the enlarged end of an axon. The contains neurotransmitters. The ______ is a cluster of RER and free ribosomes. The______ is another term for the soma of a neuron. The______ is the membrane of the axon. The______ is a cell that forms the blood 13 brain barrier. The ______ is a fine branch of an axon.

Answer 1

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.
