Question 1

You are walking through a bad part of town, down a dark alley, and carrying a large amount of cash. Behind you, you hear a door open and close suddenly, and you immediately dive into the nearest trash container. The part of the forebrain mainly responsible for your reaction is the

A)hippocampus.
B)medulla.
C)cerebrum.
D)amygdala.

amygdala.

Accepted Answer

The amygdala is primarily responsible for processing emotions, such as fear, which would trigger a fight-or-flight response in potentially threatening situations like the one described.

Question 2

The __________ cerebral hemisphere is superior at perceptual skills and detecting and expressing emotion.&#10;A)right&#10;B)left&#10;C)cortical&#10;D)subcortical

Accepted Answer

The right cerebral hemisphere is generally recognized for its superiority in perceptual skills and in the detection and expression of emotion, contrasting with the left hemisphere's strengths in language and analytical tasks.

Question 3

The limbic system is responsible for&#10;A)the control of hunger, thirst, and sex.&#10;B)executive functions.&#10;C)heartbeat and breathing regulation.&#10;D)auditory processing.

Accepted Answer

The limbic system is primarily responsible for controlling emotional responses, as well as basic drives such as hunger, thirst, and sexual desire. It does not directly manage executive functions, heartbeat and breathing regulation, or auditory processing.

Question 4

There is more somatosensory cortex for the&#10;A)mouth.&#10;B)shoulder.&#10;C)feet.&#10;D)legs.

Accepted Answer

The somatosensory cortex is a part of the brain that processes sensory information from the body. It has a topographical representation of the body, known as the somatosensory homunculus, where different body parts are represented in different regions. The amount of cortex dedicated to a body part is proportional to the sensitivity and functional importance of that part, not its size. The mouth, especially the lips and tongue, has a very high density of sensory receptors, making it one of the most sensitive areas of the body. This is why a larger portion of the somatosensory cortex is devoted to the mouth compared to the shoulder, feet, or legs, allowing for detailed sensory processing and fine motor control in this area.

Question 5

Experiments with animals have found pleasure centers to be located in the&#10;A)pituitary gland.&#10;B)left parietal lobe.&#10;C)hypothalamus.&#10;D)amygdala.

Accepted Answer

The hypothalamus is known to contain pleasure centers, as discovered in experiments with animals.

Question 6

Which of the following involves electrical brain wave measurement?&#10;A)clinical studies&#10;B)ablation&#10;C)mri scan&#10;D)eeg

Accepted Answer

EEG (Electroencephalography) involves the measurement of electrical brain wave activity, which is its primary purpose.

Question 7

Which of the following is most involved in the production of emotion?&#10;A)the occipital lobe&#10;B)the limbic system&#10;C)the medulla&#10;D)the pituitary gland

Accepted Answer

The limbic system is most involved in the production of emotion, as it includes structures such as the amygdala and hippocampus that are key in processing emotions.

Question 8

The functions of the amygdala include&#10;A)delivery of electrical stimulation to the limbic system.&#10;B)stopping electrical stimulation to the limbic system.&#10;C)stimulating the &#34;pleasure&#34; centers of the limbic system.&#10;D)helping us react to dangerous stimuli through a quick fear response.

Accepted Answer

The amygdala plays a crucial role in processing emotions, particularly fear, and helps us react to dangerous stimuli through a quick fear response, making it essential for survival.

Question 9

The __________ area in the brain acts as a final &#34;switching station&#34; for most incoming sensory information.&#10;A)superior colliculus&#10;B)reticular formation (rf)&#10;C)autonomic nervous system&#10;D)thalamus

Accepted Answer

The thalamus acts as a major relay station for most sensory information, directing it to the appropriate areas of the brain for processing.

Question 10

__________ measures the structure of the brain by utilizing a series of x-rays.&#10;A)eeg&#10;B)ct scan&#10;C)mri scan&#10;D)pet

Accepted Answer

A CT (Computed Tomography) scan measures the structure of the brain by utilizing a series of x-rays to create detailed images.

Question 11
