Question 1

Maya has experienced brain damage that has left her with difficulty sleeping and the problem of being hyperaroused.Which area of the brain was most likely damaged?

Accepted Answer

The answer of Maya has experienced brain damage that has...

Question 2

Which of the following is most likely to be hindered by damage to the somatic nervous system?

Accepted Answer

The somatic nervous system is responsible for controlling voluntary movements, such as walking and reaching for an object. Damage to this system would likely hinder the ability to perform these actions.

Question 3

What is the term for the system comprised of the somatic nervous system and the autonomic nervous system?

Accepted Answer

The system comprised of the somatic nervous system and the autonomic nervous system is called the peripheral nervous system.

Question 4

Hannah is home alone late at night when she hears a loud,frightening noise.Her heart begins pounding,her muscles tense up,and her senses sharpen.Which of the following systems is causing Hannah's reaction?

Accepted Answer

The sympathetic nervous system is responsible for the fight or flight response, which involves increasing heart rate, muscle tension, and sensory awareness in response to a perceived threat. This is likely the system causing Hannah's reaction to the frightening noise. The limbic system is also involved in emotional processing and memory, but it is not specifically responsible for physiological responses like increased heart rate. The parasympathetic nervous system is responsible for the body's "rest and digest" response, which is the opposite of the fight or flight response. The central nervous system refers to the brain and spinal cord and is not a specific system involved in this physiological response.

Question 5

Sandra had part of her brain removed to control epilepsy and as a result she can no longer solve problems that require visual imagery.What area of the brain did Sandra have removed?

Accepted Answer

Problem-solving that requires visual imagery is typically associated with the right hemisphere of the cortex. Therefore, if Sandra can no longer perform these tasks, it is likely that part of her right hemisphere was removed during the procedure.

Question 6

If you put all the neurons from a brain in a hat and randomly selected one,which area would the neuron most likely have come from?

Accepted Answer

The cerebral cortex contains the majority of neurons in the brain and is responsible for many high-level functions such as perception, movement, and memory.

Question 7

Wayne knows he takes a medication that causes an increase in the amount of neurotransmitter activity in the brain.What process is being affected by the medication?

Accepted Answer

The medication affects the reuptake process, which involves the reabsorption of neurotransmitters by the neuron that released them. By inhibiting reuptake, the medication increases neurotransmitter activity in the brain.

Question 8

Alex has a form of epilepsy that affects his limbic system.What sort of behaviour is Alex most likely to display while having a seizure?

Accepted Answer

Epilepsy affecting the limbic system can result in unusual emotional expressions and aggression during seizures. Changes in mood and behavior are common in limbic seizures due to involvement of the part of the brain responsible for emotions and memory. Lack of body posture and uncoordinated movement are more commonly seen in seizures affecting the motor cortex, while disturbed sleep and difficulty breathing may occur in certain types of seizures but are not specific to epilepsy affecting the limbic system.

Question 9

If you had to choose one brain area to protect so that you could stay alive,which would it be?

Accepted Answer

The brain stem is responsible for regulating essential bodily functions such as breathing and heart rate. Damage to the brain stem can quickly lead to death. Therefore, protecting the brain stem is essential for survival.

Question 10

What is the major function of the peripheral nervous system?

Accepted Answer

The answer of What is the major function of the...

Question 11

Which of the following parts of the brain is most associated with memory,thought,and reasoning?

Accepted Answer

The frontal lobe is responsible for executive functions such as memory, thought, and reasoning.

Question 12

Janice is having difficulty maintaining her balance and coordinating her muscle movements.Assuming her problems result from a brain injury,which of the following would you first examine?

Accepted Answer

The cerebellum is responsible for coordinating muscle movements and maintaining balance, so it would be the first area to examine in someone experiencing those symptoms. The medulla, thalamus, and midbrain are important areas of the brain but are not directly involved in motor coordination and balance.

Question 13

Dr.Henry wants to increase the amount of serotonin circulating in Brian's brain.What specific type of drug will Dr.Henry choose to prescribe?

Accepted Answer

An agonist is a drug that mimics the function of a neurotransmitter, in this case, serotonin. By prescribing an agonist, Dr. Henry will increase the amount of serotonin circulating in Brian's brain, which can help to alleviate symptoms of depression and anxiety. Antagonists, on the other hand, block the activity of a neurotransmitter, while decelerators and placebos have no effect on neurotransmitter function.

Question 14

You read in the newspaper that a mother lifted a car to free her trapped child.Which of the mother's systems was highly activated to perform this feat?

Accepted Answer

The sympathetic nervous system is responsible for the body's fight or flight response in stressful situations. In this case, the mother is likely experiencing extreme stress and adrenaline is released, activating the sympathetic nervous system and giving her the strength to lift the car. The other systems listed are not directly involved in physical strength or the fight or flight response.

Question 15

Martha suffered a serious head injury and has since experienced difficulty recognizing specific sights and sounds.Which lobe of her brain has most likely been damaged?

Accepted Answer

The temporal lobe is responsible for processing auditory information and plays a significant role in memory formation and recognizing specific sights and sounds. Damage to this area can result in difficulty recognizing familiar objects or faces, and difficulty processing auditory information.

Question 16

Where in the brain are verbal and cognitive processes usually controlled?

Accepted Answer

Verbal and cognitive processes are usually controlled in the left hemisphere of the cortex. This is because the left hemisphere is responsible for language processing and analytical thinking, which are important components of verbal and cognitive processes.

Question 17

What does the peripheral nervous system include?

Accepted Answer

The peripheral nervous system consists of the somatic and autonomic nervous system, while the brain, spinal cord, and endocrine system are part of the central nervous system.

Question 18

Jeffrey is writing a paper on philosophical theories of morality.Which part of Jeffrey's brain would a PET scan show to be most active at this time?

Accepted Answer

The cerebral cortex is responsible for higher order thinking, such as reasoning and processing complex information, which would be necessary for writing a paper on philosophical theories of morality. PET scans can show increased activity in certain regions of the cerebral cortex during specific tasks, indicating that this part of the brain is being used more heavily.

Question 19

Christina sits down to relax in her soft chair after a long,tiring day.As she sits reading her paper,she grows more relaxed.Her breathing and heart rate slow down and her muscles loosen.Which of the following systems is causing Christina's relaxation?

Accepted Answer

The parasympathetic nervous system is responsible for the body's rest and relaxation response. It slows down heart rate, respiration, and other bodily functions for relaxation, which is what is happening to Christina as she sits in her soft chair.

Question 20

What part of the brain stem regulates vital activities such as heartbeat,breathing,and digestion?

Accepted Answer

The hindbrain is responsible for regulating vital activities such as heartbeat, breathing, and digestion. Specifically, the medulla oblongata, which is part of the hindbrain, controls involuntary functions such as heart rate, breathing, and blood pressure.
