Question 1

How can synaptic vesicles continue to pour out their neurotransmitters, and yet still have a ready supply of neurotransmitters to respond to continuing stimulation?

Accepted Answer

A)  Through the process of reuptake, they absorb some of the neurotransmitter left in the gap between the axon and the dendrite. 
B)  Other nearby cells donate a portion of neurotransmitter to the vesicle in need, through a process called "synaptic transfer." 
C)  The vesicles never fire completely, always holding a little amount of neurotransmitter back. 
D)  The cells re-energize with every firing.

Question 2

How were endorphins discovered and what are their major functions in the brain?

Accepted Answer

Researchers demonstrated that some receptor sites were activated by opiates, such as morphine and heroin, and then discovered chemicals in the brain that activated these same receptor sites. They named these chemicals endorphins.

Question 3

Define the term plasticity and describe its role in recovery from brain damage.

Accepted Answer

Plasticity is the ability of the brain to reorganize and compensate for brain damage. The brain can grow new neurons, damaged neurons can grow new axons, and neurons can expand their dendrites to make new synaptic connections with other neurons.

Question 4

Receptor sites on the receiving neuron

Accepted Answer

A)  receive any available neurotransmitter molecules. 
B)  can only be influenced by neurotransmitters from a single neuron. 
C)  receive only neurotransmitter molecules of a specific shape. 
D)  are located only on the dendrites. 
A)  receive any available neurotransmitter molecules. 
B)  can only be influenced by neurotransmitters from a single neuron. 
C)  receive only neurotransmitter molecules of a specific shape. 
D)  are located only on the dendrites.

The frontal lobe is to ________ as the parietal lobe is to ________.

Accepted Answer

A)  general knowledge storage; speech production

C)  understanding auditory input; motor control 
D)  sensory input; vision
