3. grey matter: brownish-grey nerve tissue consisting of mainly __?__ within the brain and spinal cord
4. Which part of the autonomic nervous system helps us respond to stress?
5. Which part of the peripheral nervous system do we have conscious control over?
6. _?_ carry information from receptor cells to the CNS.
7. _?_ carry information from the CNS to effectors like muscles.
8. Modulators of the CNS are composed of these type neurons.
9. Nerves always fire with the same intensity. Either they fire or they don’t. This notion is referred to as
the ___?___ response.
10. As the action potential moves down a neuron it begins in the _?_ moves along the cell body & axon to
the axon terminals.
11. At resting potential neurons have which type of charge inside? (Pos. or Neg.)
12. Which lobe of the human brain is responsible for hearing association?
13. When an action potential is set up in a neuron what is the charge inside the neuron?
14. What channels open to cause an action potential.
15. What is responsible for restoring the resting potential after an action potential has passed.
16. Is the sodium potassium pump active transport or passive transport?
17. What term refers to the time required for the resting potential to reestablish so another action potential
can be fired?
18. The name given to the space between the axon terminal of one neuron and the dendrite of the next
neuron.
19. The name given to specialized vacuoles in the axon terminal. These special vacuoles contain
neurotransmitters.
20. The name given to the neuron BEFORE the synapse.
21. The name given to chemicals that carry the nerve impulse across the synapse.
22. The ions that stimulate neurotransmitter release.
23. The ions channels that open to allow an action potential to establish.
24. The minimum stimulus required to set up an action potential.
25. The neuron pathway used in a reflex. This type of nerve pathway involves all three types of neurons.
26. The _?_ cells are responsible for secreting the myelin sheath.
27. The purpose of the myelin sheath is to _?_ _?_ nerve transmission.
28. The _?_ response is a process in which the postsynaptic neuron is made more negative on the inside
to raise the threshold of stimulus.
29. The primary neurotransmitter that causes excitation in the somatic nervous system.
30. The main neurotransmitter that causes excitation in the cerebrum. This neurotransmitter is actually a
type of amino acid.
31. The main neurotransmitter that inhibits nerve transmission in the brain.
32. The Primary neurotransmitter of the sympathetic nervous system (excitatory).
33. Which neurotransmitter is involved in the alteration of mood.
