Question 1

Functional magnetic resonance imaging detects where more brain activity is occurring by ___________.&#10;A)detecting the amount of oxygen that is being brought to a particular place in the brain.&#10;B)where atoms are pulling apart.&#10;C)tracking the path of radiation.&#10;D)simply having a sharp image of the brain.

Accepted Answer

This is how fMRI works - by detecting the amount of oxygen that is located in certain areas of the brain.

Question 2

The hypothalamic-pituitary-adrenal (HPA)axis may be activated by which of the following stimuli?&#10;A)leukocytes&#10;B)basophils&#10;C)stimulation of the occipital lobe&#10;D)pain.

Accepted Answer

Pain can cause the hypothalamus to send messages to the pituitary gland, thus activating the adrenal glands.

Question 3

When a neuron fires, it fires in a(n)________ fashion, because there is no such thing as &#34;partial&#34; firing.&#10;A)all-or-none&#10;B)rapid fire&#10;C)accidental patterned&#10;D)quick succession

Accepted Answer

This is the term used to describe how neurons fire according to the book.

Question 4

Ever since he suffered a brain injury by falling from a ladder, his wife has continued to tell the doctor that his personality has changed.He used to be fun loving and care-free, but he is now more critical and yells at his children for seemingly little reason.Zack is likely to have suffered damage to the _______ of his cortex.

A)occipital lobe
B)parietal lobe
C)temporal lobe
D)frontal lobe

Accepted Answer

The frontal lobes are connected to personality and decision making processes.

Question 5

The thalamus is often compared to a(n)________.&#10;A)switching center&#10;B)fast food menu&#10;C)stop sign&#10;D)bus stop

Accepted Answer

As your authors note, the thalamus is often compared with switching center because it routes sensory information to different parts of the cerebral cortex.

Question 6

LaKeisha stepped on a piece of glass and quickly pulled her foot away from that sharp object.Which of the following are responsible for sending a message to the muscles in LaKeisha's foot, resulting in her pulling her foot away from the piece of glass?

A)motor neurons
B)interneurons
C)sensory neurons
D)reflexes

Accepted Answer

Motor neurons carry messages from the central nervous system to the muscles of the body.

Question 7

Agonist is to antagonist as:&#10;A)neuromodulator is to neurotransmitter.&#10;B)reuptake is to receptor.&#10;C)mimic is to block.&#10;D)block is to mimic.

Accepted Answer

Agonists mimic neurotransmitters by stimulating specific receptor sites, and antagonists block receptor sites.

Question 8

After a head injury a person reports that she is unable to see, although her eyes are uninjured.A doctor would suspect an injury in the ______ lobe.&#10;A)occipital&#10;B)parietal&#10;C)temporal&#10;D)frontal

Accepted Answer

The occipital lobes contain the visual centers of the brain.

Question 9

If a person were to damage the speech center in the brain, the ideal age for this to happen would be&#10;A)2)&#10;B)14.&#10;C)33.&#10;D)61.

Accepted Answer

Plasticity in the brain is maximized during our childhood years, so damage would most likely be adjusted for when the child was young rather than older.

Question 10

A specialized cell that makes up the nervous system that receives and sends messages within that system is called a _________.&#10;A)glial cell&#10;B)neuron&#10;C)cell body&#10;D)myelin sheath

Accepted Answer

A neuron is a specialized cell that makes up the nervous system that receives and sends messages within that system.
