Use the following information to answer the first two questions.
 


Persons affected by panic attacks appear to be "sensitive" to CCK. This hypothesis would be supported if such persons were found to have
Question 36 options:

1)

impaired production of CCK

2)

CCK inhibitors at these synapses

3)

low levels of CCK

4)

excess postsynaptic receptors for CCK

Question 37 (1 point)
Injections of CCK produce responses similar to those produced by the stimulation of
Question 37 options:

1)

parasympathetic motor neurons

2)

interneurons

3)

sensory neurons

4)

sympathetic motor neurons

Question 38 (1 point)
Use the following information to answer the next three questions.

 


For neurotransmitters, dopamine and acetylcholine, the releasing sites and the receptor sites are, respectively,
Question 38 options:

1)

cell bodies and dendrites

2)

dendrites and Schwann cells

3)

axon terminals and Schwann cells

4)

axon terminals and dendrites

Question 39 (1 point)
What role do both dopamine and acetylcholine have when they function as excitatory neurotransmitters?
Question 39 options:

1)

They make the postsynaptic membrane more permeable to K+ ions.

2)

They make the postsynaptic membrane more permeable to Na+ ions.

3)

They make the presynaptic membrane more permeable to K+ ions.

4)

They make the presynaptic membrane more permeable to Na+ ions.

Question 40 (1 point)

Use the following information to answer the next question.
 



Would it be reasonable to use NGF to regenerate neurons in which nuclei had been destroyed?
Question 40 options:

1)

No, because without the nucleus to actively transport ions, the cell would die.

2)

Yes, because not all cells are require a nucleus to function.

3)

Yes, because organelles other than the nucleus cause growth.

4)

No, because the nucleus controls protein synthesis and homeostasis.



Which of the following statements presents a valid interpretation of the information on the graph?
Question 43 options:

1)

A sensation of coolness is interpreted only when two types of receptors are stimulated.

2)

A temperature of 5 C is less painful than a temperature of 50 C.

3)

The threshold level of stimulation is higher for temperature receptors than it is for pain receptors.

4)

Temperature sensations are determined by the number of impulses per second and the specific type of receptors.


Question 1 (1 point)

The structure containing the cell nucleus of the neuron is:

Question 1 options:

1)

synapsis


2)

dendrite

3)

cell body


4)

axon


 

A lack of acetylcholinesterase would cause nerves to
Question 7 options:

1)

become fatigued

2)

fail to reach threshold levels

3)

become repolarized

4)

fire repeatedly causing spasms and tremors
Question 8 (1 point)

The size of the reaction depends upon the
Question 8 options:

1)

distance of the stimulation from the reaction muscles

2)

size of the impulses received

3)

number of impulses received by the brain

If the left thumb is pricked, the impulse will be transmitted to
Question 20 options:

1)

the right cerebellum

2)

the left cerebral cortex

3)

the left cerebrum

4)

the right cerebral cortex

Thank you!

4)

number and size of the impulses received
