Question 1

Handyman Bob just hit his thumb with a hammer; the sensation will be transmitted to the central nervous system by _____ nerve fibers. ​

Accepted Answer

Afferent nerve fibers are responsible for transmitting sensory signals, including pain, from the body to the central nervous system.

Question 2

The _____ fluid nourishes the brain and provides a protective cushion for it. ​

Accepted Answer

Cerebrospinal fluid surrounds the brain and spinal cord, providing nourishment and acting as a cushion to protect these vital structures.

Question 3

The _____ nervous system mobilizes the body when one needs to exert tremendous energy (such as to flee from an attacker).

Accepted Answer

The sympathetic nervous system is responsible for the body's "fight or flight" response, which mobilizes the body to exert tremendous energy in situations of stress or danger, such as fleeing from an attacker.

Question 4

Destroying a piece of brain tissue to observe its effect on behavior is referred to as

Accepted Answer

Lesioning is the process of destroying a piece of brain tissue to observe its effect on behavior. This technique is used in neuroscience research to study the functions of specific areas of the brain.

Question 5

Electrical stimulation of its lateral hypothalamus causes an animal to overeat and become obese. Therefore, we would expect that lesioning the lateral hypothalamus would produce ​

Accepted Answer

Lesioning the lateral hypothalamus typically results in reduced food intake and weight loss because this area of the brain is involved in promoting eating and body weight gain.

Question 6

The central nervous system consists of the

Accepted Answer

The central nervous system (CNS) is comprised of the brain and the spinal cord, which serve as the main processing center for the entire nervous system and control all the functions of the body.

Question 7

The brain-imaging method that uses multiple X-rays to generate a picture of a horizontal slice of the brain is ​

Accepted Answer

Computerized tomography (CT) uses multiple X-rays to create a detailed image of the brain's structure, allowing for the visualization of horizontal slices of the brain.

Question 8

The _____ is MOST likely to be in control of bodily processes during periods of rest and recovery for the body.

Accepted Answer

The parasympathetic nervous system is primarily responsible for the body's rest and digest functions, helping the body to relax and recuperate after periods of stress or activity.

Question 9

Sigourney's doctors think she might have a tumor, and they would like to use a brain-imaging technique that will provide them with an accurate image of her brain structure.  They are MOST likely to use

Accepted Answer

A computerized tomography (CT) scan is most commonly used to obtain a very detailed image of the brain's structure, which is essential for identifying tumors.

Question 10

The part of the nervous system that controls digestion and blood flow is the _____ nervous system.

Accepted Answer

The autonomic nervous system controls involuntary bodily functions, including digestion and blood flow, without conscious effort.

Question 11

Sam is highly relaxed. His blood pressure and heart rate are lower than usual. This relaxation response was MOST likely the result of activity in his _____ nervous system.

Accepted Answer

The parasympathetic nervous system is responsible for the body's rest and digest response, which lowers heart rate and blood pressure, promoting relaxation.

Question 12

While the _____ nervous system is associated with conserving bodily resources, the _____ nervous system mobilizes the body's resources for emergencies. ​

Accepted Answer

The parasympathetic nervous system is responsible for conserving energy and promoting rest-and-digest functions, while the sympathetic nervous system prepares the body for action and is often referred to as the fight-or-flight response.

Question 13

Which of the following individuals is likely to be at the HIGHEST level of sympathetic arousal? ​

Accepted Answer

Bill, who is anticipating an exam for which he is unprepared, is likely to experience high levels of stress and anxiety, leading to increased sympathetic arousal. This system prepares the body for "fight or flight" responses, which would be activated in situations of stress or fear, such as facing an unprepared exam.

Question 14

The movement of voluntary skeletal muscles involved in doing calisthenics is under the control of the _____ nervous system.

Accepted Answer

The somatic nervous system is responsible for the voluntary movement of skeletal muscles, such as those movements involved in calisthenics.

Question 15

The technique in which radioactive markers are introduced into the brain and then equipment monitors where the chemicals appear in the brain is ​

Accepted Answer

Positron emission tomography (PET) is the technique where radioactive markers are introduced into the body (including the brain) to observe how tissues and organs are functioning by detecting where the radioactive chemicals concentrate.

Question 16

Which of the following research techniques is LEAST likely to be used to study the human brain?

Accepted Answer

Lesioning, which involves deliberately damaging brain tissue to study its effects, is less commonly used today due to ethical concerns and the development of non-invasive techniques like MRI and PET scans.

Question 17

The fight-or-flight response is a direct result of activation of the _____ nervous system.

Accepted Answer

The fight-or-flight response is a direct result of activation of the sympathetic nervous system, which prepares the body to respond to perceived threats by increasing heart rate, blood pressure, and releasing stored energy.

Question 18

Electrical stimulation of the brain involves ​

Accepted Answer

Electrical stimulation of the brain specifically refers to the process of sending a weak electric current into a brain structure to stimulate or activate that structure. This technique is used in both research and clinical settings to explore the functions of different brain areas and to treat certain neurological conditions.

Question 19

Edmund was walking down a dark street when he heard a car backfire. His heart started to race and he began to perspire in response to this sudden, startling noise. These physical reactions were triggered by Edmund's ​

Accepted Answer

Edmund's physical reactions of a racing heart and perspiration in response to a sudden, startling noise are triggered by the sympathetic nervous system, which is part of the autonomic nervous system responsible for the body's 'fight or flight' response to stress or danger.

Question 20

The heart, glands, and smooth muscles are controlled by the _____ nervous system.

Accepted Answer

The autonomic nervous system controls the heart, glands, and smooth muscles, regulating involuntary body functions such as heart rate and digestion.
