1. receptors which perceive pain
2. tumors formed by over-reproduction of glial cells; commonly known as
brain tumors
3. whitish, fatty covering which protects and insulates nerve fibers
4. short, branched afferent process of a neuron
5. bundles of neuron processes in the CNS
6. long, slender, efferent process of a neuron
7. nerve cell which conducts an impulse
8. nerve type which conducts an impulse to the CNS
9. processing and interpreting sensory input and making decisions about
what should be done
10. nerve endings which are sensitive and respond to light energy
11. stimulus strength strong enough to cause a response
12. when one pre-synaptic neuron affects a response in two post-synaptic
neurons
13. ovoid glial cells that are phagocytic
14. not having the ability to reproduce
15. clusters of neuron cell bodies found in the PNS
16. a chemical which diffuses across the synapse in order to affect a postsynaptic neuron
17. stimulus strength NOT strong enough to cause a response
18. when these “burst”, they release neurotransmitters into the extracellular
space.
19. glial cells that produce cerebrospinal fluid
20. an excitatory neurotransmitter
21. axonal plasma membrane
22. these neurotransmitters open ionic channels and increase the
responsiveness of postsynaptic cells
23. portion of the Schwann cell which surrounds the myelin sheath
24. nerve c ell types which do not conduct an impulse
25. the junction or space where two neurons communicate
