2) many different types of integral membrane ion channels

3) microtubules located in axons

4) mitochrondria located at the axon terminal

5) these are all found in neurons

2. describe the after-hyperpolarization phase of the action potential is due to

1) A decrease in the membrane permeability of K+

2) An increase in the membrane permeability of K+.

3) A decrease in the membrane permeability of Na+.

4) An increase in the membrane permeability of Na+.

5) None of the above

3. describe Catecholamine neurotransmitters are commonly synthesized

1) In the soma.

2) On microtubules.

3) In glia.

4) In the nerve terminal.

5) In the synaptic cleft.

6) In dendrites.

4. describe IP3 acts as a secondary messenger in the cell because

1) it catalyses the production of cGMP

2) it activates Protein Kinase C

3) it causes the release of calcium from intracellular stores

4) it binds with glutamate channels

5) none of the above

5.  describe Brodmann first defined areas of the neocortex based on differences in

1) function.

2) electrical activity.

3) neurotransmitter concentrations.

4) ionic concentrations.

5) cytoarchitecture cell shape and arrangement)

1) sagittal plane

2) parasagittal plane

3) transverse plane

4) coronal plane

5) none of the above

7.  describe the Na+/K+ ATPase uses ATP energy to move 3 Na+ ions out of the cell as well as 2 K+ ions into the cell:

1) true

2) false

8.  describe an action potential initiates at the axon hillock and not in the soma or dendrites because

1) There is a concentration of voltage-gated sodium channels at this site.

2) The soma and dendrites have few voltage-gated sodium channels.

3) The membrane potential of the soma and dendrites is unable to reach threshold (-55mV).

1) true

2) false
