Nervous System Part I

3. Largest glial cells of the CNS that helps maintain BBB
4. This structural type of neuron is likely to be found as a sensory neuron in your skin
7. This division of the autonomic system controls your “flight or fight” response
10. This functional division delivers information FROM the CNS
12. This is the end of the axon where neurotransmitters are released
13. The cells with the ability to send electrical messages, generally cannot divide
16. Phagocytes of the CNS
18. This functional division brings information IN to the CNS
19. This part of the neuron is the area the impulse travels along
21. Myelinate axons of the CNS
22. Produce cerebrospinal fluid
23. This part of the neuron protects and insulates the axon, and is made from glial cells
25. Made up of the brain and spinal cord (abbreviation)
26. This structural type of neuron is uncommon and likely to be found in your retina
27. A type of functional neuron that brings information to the CNS

1. This functional type of neuron only sends/receives messages from other neurons
2. These projections of a neuron receive signals
5. Cells that myelinate the axons of the PNS
6. This functional type of neuron is associated with movement, while it controls muscles it can deliver messages to other effectors as well
8. This division of the autonomic system is in control of “rest and digestion”
9. Often a motor neuron this structural type of neuron is also the most common found in your brain
11. These spaces between myelin sheaths help speed up the transmission of the signal along the axon
14. This division of the efferent system controls primarily skeletal muscles
15. These cells of the PNS wrap around neurons to support
17. One of the two main components of the CNS
20. A category of cells that provide support and protection for neurons
24. The space in between the axon terminal of one neuron and the dendrites of another where neurotransmitters are released and absorbed
