Question 1

The satiety center of the brain is found in which area(s)of the hypothalamus?
A)bottom middle part
B)side portions
C)top part
D)direct center

Accepted Answer

A

Question 2

Carolyn was diagnosed with cancer of the stomach.Her stomach was surgically removed.After the operation,she will probably
A)feel hungrier and eat more.
B)starve unless force fed.
C)feel no hunger but will eat because she still feels thirst.
D)continue to feel hungry and eat regularly.

Accepted Answer

D

Question 3

The satiety center of the brain is found in the _______ hypothalamus.
A)lateral
B)ventromedial
C)cortical
D)endometrial

Accepted Answer

The ventromedial hypothalamus is responsible for regulating feelings of satiety or fullness. Lesions in this area can lead to overeating and obesity. The other options, lateral hypothalamus and cortical hypothalamus, are not directly involved in regulating satiety. The term "endometrial" is not related to the brain's satiety center.

Question 4

Which of the following would have the LEAST effect on feelings of hunger?
A)removing a person's stomach
B)weight dropping below the body's "set point"
C)removing the hypothalamus
D)the sugar level of the blood being low

Accepted Answer

Removing a person's stomach would have the most effect on feelings of hunger as the stomach plays a large role in signaling the brain to feel full or hungry. The other options may have some effect on hunger, but removing the stomach would have the most significant impact.

Question 5

When you are hungry,your stomach lining produces ghrelin,a hormone that activates your
A)lateral hypothalamus.
B)vertromedial hypothalamus.
C)cortical region of the pons.
D)corpus callosum.

Accepted Answer

Ghrelin activates the lateral hypothalamus, which is known to stimulate hunger and increase food intake.

Question 6

Regarding the mechanisms of hunger,which of the following statements is FALSE?
A)When you are hungry,your stomach lining produces ghrelin.
B)Ghrelin activates parts of the brain involved in learning.
C)One should study immediately after eating,not before you eat.
D)Ghrelin is a hormone that activates a person's lateral hypothalamus.

Accepted Answer

This statement is false. It is actually recommended to study before eating, as digesting food can make you feel sleepy and less focused.

Question 7

The most critical physiological factor controlling hunger is the
A)level of blood sugar.
B)presence of stomach contractions.
C)taste of food.
D)the stretching or distention of the abdomen.

Accepted Answer

The level of blood sugar is the most critical physiological factor controlling hunger because when blood sugar levels drop, it signals the brain to trigger hunger and increase appetite. This is because the body needs food to replenish glucose levels and provide energy. When blood sugar levels are high, the body releases insulin to bring it back down, which can also trigger hunger because the body needs more glucose to balance out the insulin. Stomach contractions, taste of food, and abdominal distension can all influence hunger and appetite, but they are not as critical as blood sugar levels.

Question 8

People who have had their stomachs surgically removed
A)report they still have hunger pangs.
B)may fail to eat regularly.
C)must be force fed.
D)still experience hunger.

Accepted Answer

The answer of People who have had their stomachs surgically...

Question 9

Clarence suffered a stroke that destroyed his lateral hypothalamus (LH).This damage is likely to cause Clarence to
A)refuse to eat.
B)never feel full.
C)overeat.
D)experience massive weight gain without overeating.

Accepted Answer

The lateral hypothalamus (LH) is involved in promoting feeding behavior. Damage to this area can lead to a lack of interest in eating or refusal to eat.

Question 10

Which part of the brain regulates hunger by responding to blood sugar levels as well as combining neural messages received from the liver and stomach?
A)thalamus
B)hypothalamus
C)midbrain
D)hippocampus

Accepted Answer

The hypothalamus is responsible for regulating hunger and satiety by responding to blood sugar levels as well as combining neural messages received from the liver and stomach. The thalamus is responsible for relaying sensory information, the midbrain for coordinating motor movements and the hippocampus for memory formation.

Question 11

The feeding center of the brain is found in the _______ hypothalamus.
A)lateral
B)ventromedial
C)cortical
D)endometrial

Accepted Answer

The answer of The feeding center of the brain is...

Question 12

Which of the following scientists performed an experiment that conisted of one of the scientists swallowing a balloon that was inflated so that the movements of the stomach could be recorded?
A)Dollard and Miller
B)Yerkes and Dodson
C)Cannon and Washburn
D)James and Lange

Accepted Answer

Cannon and Washburn performed the experiment where Washburn swallowed a balloon and the movements of his stomach were recorded to demonstrate the physiological aspects of hunger.

Question 13

The feeding center of the brain is found in which area(s)of the hypothalamus?
A)bottom middle part
B)side portions
C)top and bottom parts
D)center

Accepted Answer

The answer of The feeding center of the brain is...

Question 14

Cutting sensory nerves from the stomach,or removing it entirely,causes
A)a total loss of appetite.
B)eating based on recognized need,not internal feelings of hunger.
C)little change with the person experiencing the feeling of hunger and eating regularly.
D)the need for patients to be "trained" to eat;otherwise,they would inadvertently starve to death.

Accepted Answer

The stomach is not the only organ responsible for hunger signals; the brain and other hormones also play a significant role, so hunger and eating behavior can continue even without the stomach.

Question 15

In an early experiment by Cannon and Washburn,Washburn swallowed a balloon so that
A)the balloon could prevent hunger by filling up the stomach.
B)the balloon could be inflated and allow the recording of stomach contractions.
C)the balloon would stop digestion,allowing the stomach to be examined.
D)hunger could be controlled by controlling the stomach contractions.

Accepted Answer

Washburn swallowed the balloon in order to allow recording of stomach contractions. The balloon could be inflated inside the stomach so that changes in stomach size could be measured and correlated with feelings of hunger.

Question 16

Which area of the brain contains both the feeding center and the satiety center?
A)amygdala
B)medulla
C)hypothalamus
D)hippocampus

Accepted Answer

The hypothalamus is the area of the brain that contains both the feeding center (which stimulates hunger) and the satiety center (which signals when we are full). The amygdala is involved in emotions like fear and aggression. The medulla is responsible for controlling many automatic functions of the body, such as breathing and heart rate. The hippocampus is important for memory formation and retrieval.

Question 17

When you are hungry,your stomach lining produces a hormone that activates your lateral hypothalamus,with this hormone called
A)oxytocin.
B)throxin.
C)ghrelin.
D)insulin.

Accepted Answer

The hormone produced by the stomach lining that activates the lateral hypothalamus when we are hungry is called ghrelin.

Question 18

If the lateral hypothalamus is destroyed in a starving animal,the animal will
A)overeat drastically.
B)become unusually sensitive to external cues for eating.
C)become unusually sensitive to internal cues for eating.
D)refuse to eat.

Accepted Answer

The lateral hypothalamus is responsible for stimulating appetite and initiating eating behavior. Therefore, if it is destroyed in a starving animal, the animal would not have the drive to eat and would refuse to eat.

Question 19

Regarding hunger,which of the following statements is FALSE?
A)Eating is encouraged and increases when the stomach is stretched or distended.
B)The stomach is not essential for feeling hunger.
C)The brain receives many signals from parts of the digestive system,ranging from the tongue and stomach to the intestines and liver.
D)For many people,hunger produces an overall feeling of weakness or shakiness,rather than a "growling" stomach.

Accepted Answer

Eating is actually inhibited when the stomach is stretched or distended, as this sends signals to the brain that the body is full and no longer needs more food.

Question 20

Electrically stimulating the lateral hypothalamus will cause a rat to
A)start eating.
B)stop eating.
C)go to sleep.
D)become so manic it will be unable to sleep.

Accepted Answer

Electrically stimulating the lateral hypothalamus has been shown to stimulate hunger and cause the rat to start eating. This area of the brain is known to play a role in regulating food intake and appetite.
