Across
- 2. clusters of brain cells
- 4. also known as sensory neuron, transmits impulses from the receptors to the CNS.
- 5. one branch of soma
- 8. regulates passage of molecules from blood to the brain
- 10. This type of cell ultimately produces myelin.
- 11. this type of cell supports neuron cell bodies in the ganglia of the PNS
- 14. allows axon to conduct impulses faster
- 17. smooth muscles, skeletal muscles, glands
- 19. more than two branches
- 21. nervous system that refers to the collection of neurons located throughout the digestive tract
- 22. blank conduction is nerve impulses that jump from node to node as they travel down the axon.
- 24. nerves
- 27. gap between the axon terminal
- 28. two branches of soma
- 30. carry impulses from one neuron to another
Down
- 1. nerve cells that send messages all over the body
- 3. also known as motor neuron, transmits impulses from CNS to effectors
- 6. produce myelin in the CNS
- 7. The nervous system provides control for the blank activities of the body
- 9. controls vital processes
- 12. hillock This structure connects the cell body to the axon
- 13. This type of cell lines the ventricles and helps form the choroid plexus
- 15. a system with rapid activity Endocrine- a system with slow activity
- 16. This structure is a extension of the plasma membrane that increase the surface area available to receive stimuli and transmit stimulation towards the cell body
- 18. phagocytic cells that migrate throughout the CNS removing debris|
- 20. This type of cell supports neurons
- 23. blank potentials travel the length of the axon, causing the release of neurotransmitters into the synapse. Also known as impulses
- 25. this type of cell forms fatty myelin sheaths around most axons in the PNs only. Also known as Neurolemmocytes.
- 26. Nodes of blank are gaps between segments of myelin
- 29. brain and spinal cord
