Question 1

As insulin levels _______,glucose levels ________.

Accepted Answer

Insulin is a hormone that helps regulate and control blood sugar levels. When insulin levels increase, it signals cells to take up more glucose from the bloodstream, thereby decreasing blood glucose levels. Conversely, when insulin levels decrease, cells take up less glucose, leading to an increase in blood glucose levels.

Question 2

Hunger and thirst are examples of

Accepted Answer

Hunger and thirst are examples of internal physiological states that motivate an organism to take action to fulfill a biological need. These states are referred to as drives. Rewarded behaviors increase the likelihood of the behavior occurring again, while punished behaviors decrease the likelihood of the behavior occurring again. Incentives are external stimuli that motivate behavior, such as rewards or punishments. Therefore, D is the best choice as hunger and thirst are examples of drives.

Question 3

The tendency of the body to maintain a steady state of functioning is called

Accepted Answer

Homeostasis refers to the body's ability to maintain a stable internal environment despite fluctuations in external conditions. This includes regulating temperature, water balance, and other physiological variables to keep the body within a certain range of functioning. Other options such as stability, drive reduction, and allostatic load are related but do not encompass the full concept of homeostasis.

Question 4

Luisa is working out at a gym and her body temperature begins to rise.To cool itself down,her body begins to sweat.After showering however,her body temperature drops below ideal,so her body begins to shiver to warm itself up.This example illustrates the concept of

Accepted Answer

Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in the external environment. In this example, Luisa's body temperature rises during exercise and then drops below ideal after showering, but her body responds with sweating and shivering to bring her temperature back to a stable level, demonstrating the concept of homeostasis.

Question 5

The goal of motivated behaviour is often to _____________ a drive.

Accepted Answer

The goal of motivated behavior is often to reduce a drive, which is a psychological tension or discomfort that motivates the individual to act in a way that will reduce this discomfort or satisfy a need.

Question 6

Dr.Pourhamzeh lesions an area of the brain in a rat.He notices that after the procedure the rat eats almost continuously.It is likely that Dr.Pourhamzeh has lesioned the

Accepted Answer

Lesioning the ventromedial hypothalamus is known to cause hyperphagia or overeating behaviors in animals. This area of the brain is involved in regulating satiety and controlling feeding behavior.

Question 7

The psychology of motivation can be best summarized as the study of

Accepted Answer

The psychology of motivation is focused on understanding the processes that drive goal-directed behavior, including the underlying psychological and neurological mechanisms. This involves examining factors such as intrinsic and extrinsic motivation, the role of emotion, cognitive beliefs and attitudes, and the influence of social and cultural factors. While rewards and punishments do play a role in motivating behavior, it is only one aspect of motivation that is studied in this field.

Question 8

A(n)_________ is a biological trigger that helps us to seek out the necessities for survival.

Accepted Answer

A drive is a fundamental biological trigger that helps us seek out necessities like food, water, and sex. It's usually characterized by a strong internal impulse or desire that pushes us to take specific actions to satisfy a need. In contrast, an incentive is something external that motivates us to act, such as a reward or punishment. Impulse refers to a sudden urge or impulse to act, while consequence is the result or outcome of an action.

Question 9

Jake is nervous about his upcoming curling match.Despite having just eaten a large meal,his stomach starts to growl.What hormone is likely responsible for Jake's current feeling of hunger?

Accepted Answer

Ghrelin is known as the hunger hormone and is secreted by the stomach when it is empty or when the body needs energy. Therefore, it is likely responsible for Jake's feeling of hunger despite having eaten a large meal. Insulin is a hormone that regulates blood sugar levels and is not typically associated with feelings of hunger. Glucose is a type of sugar that is used as a fuel source by the body, so it is not a hormone. CCK (cholecystokinin) is a hormone that is released by the small intestine in response to food, but it is more associated with feelings of satiation or fullness rather than hunger.

Question 10

_______ is a hormone that is released in response to stress,but is also responsible for stomach contractions and appetite.

Accepted Answer

Ghrelin is the hormone that is released in response to stress and is also responsible for stomach contractions and appetite. CCK (cholecystokinin) is a hormone that is released in response to the presence of food in the small intestine, and is responsible for reducing appetite. Glucose and insulin are involved in regulating blood sugar levels.

Question 11

Phyllis feels hungry even after she has eaten large meals and has been gaining weight.A doctor diagnoses her with a neurological disorder that affects a specific structure in the brain.Which brain region has likely been affected?

Accepted Answer

The hypothalamus is responsible for regulating hunger and satiety, among other homeostatic functions. A disorder affecting this region could lead to the symptom of feeling hungry even after eating large meals and gaining weight.

Question 12

Insulin is responsible for

Accepted Answer

Insulin helps cells store circulating glucose. Insulin is the hormone responsible for regulating blood sugar levels by facilitating the uptake of glucose into cells for energy or storage, particularly in muscle and fat cells.

Question 13

Motivation that is influenced by stress,in addition to current needs,is known as

Accepted Answer

Allostasis is the process by which the body responds to stress and maintains stability. When a person is experiencing stress, their motivation to take action may be influenced by their need to reduce or cope with the stress, in addition to their current needs. This type of motivation is known as allostatic motivation. Homeostasis refers to the body's ability to maintain stability and balance, but it is not specifically related to motivation. An incentive is something that motivates or encourages behavior, but it does not necessarily involve stress. A drive is a basic, biological need that motivates behavior, but it also does not necessarily involve stress.

Question 14

When specialized cells detect __________ levels of ____________,they trigger an increase in hunger.

Accepted Answer

When blood glucose levels drop below a certain amount, specialized cells in the body detect the low levels and trigger hunger. This is because the body needs to replenish its glucose stores to maintain normal bodily functions. Insulin levels do not directly affect hunger; in fact, high insulin levels can suppress hunger.

Question 15

One factor in hunger seems to be the increase in __________,which causes blood sugar levels to eventually drop several hours after we eat.

Accepted Answer

Insulin is a hormone that helps regulate blood sugar levels by facilitating the uptake of glucose into cells for energy. When we eat, our body releases insulin to help process the glucose from the food. However, if we consume too many high-carbohydrate or sugary foods, our body may produce too much insulin, which can lead to a drop in blood sugar levels several hours later. This can result in feelings of hunger and cravings for more high-carbohydrate or sugary foods, perpetuating the cycle.

Question 16

Glucostats are

Accepted Answer

Glucostats are neurons that can detect glucose levels. They play an important role in maintaining blood sugar levels, which is crucial for the proper functioning of the body.

Question 17

The chief function of homeostasis is to

Accepted Answer

The chief function of homeostasis is to maintain a steady state or balance in the body's internal environment, despite changes in external conditions. This is essential for ensuring that cells have a stable environment in which to function optimally, and for preventing damage or dysfunction due to internal or external stressors. Homeostasis does not directly involve preparing for future events, regulating emotions, or controlling sexual urges.

Question 18

The lateral hypothalamus is likely involved with

Accepted Answer

The lateral hypothalamus has been shown to play a key role in initiating eating behavior and the feeling of hunger.

Question 19

The _______ likely serves as the "on" switch for eating behaviour,while the ______ likely serves as the "off" switch.

Accepted Answer

The lateral hypothalamus is known to serve as the "on" switch for eating behavior, while the ventromedial hypothalamus serves as the "off" switch.

Question 20

Motivation is best described as

Accepted Answer

Motivation is the process that initiates, guides, and maintains goal-oriented behaviors. This includes both physiological and psychological processes such as goal-setting, reward-seeking, and decision-making. Option A describes a physiological process related to hunger, option B describes homeostasis, and option C describes drives that motivate behavior, but do not fully capture the complex nature of motivation.
