Question 7

After suffering a brain injury by falling from a ladder, Zack's wife continues to tell the doctor that his personality has changed. He used to be fun loving and carefree, but he is now more critical and yells at his children for seemingly little reason. Zack is likely to have suffered damage to the ________ lobe of his cortex.

Accepted Answer

The frontal lobe is responsible for personality, decision-making, and impulse control. Damage to this area can result in changes to these behaviors, such as being more critical and having difficulty controlling one's temper. The other lobes listed do not have a primary function related to personality or mood.

Question 8

Eating, drinking, sexual motivation, and body temperature control are most strongly influenced by the ________.

Accepted Answer

The hypothalamus plays a crucial role in regulating numerous functions in the body including eating, drinking, sexual motivation, and body temperature control. The hippocampus is involved in memory formation, the thalamus is important for relaying sensory information to other parts of the brain, and the amygdala is involved in emotional processing and the "fight or flight" response.

Question 9

Which of the following is a group of several interconnected brain structures involved in emotion, memory, smell, and motivation?

Accepted Answer

The limbic system is a group of several interconnected brain structures involved in emotion, memory, smell, and motivation. The cerebellum is mainly responsible for motor coordination and balance, the cerebral cortex is involved in conscious thought and voluntary action, and the neocortex is the outermost layer of the cerebral cortex responsible for higher cognitive functions like language and reasoning.

Question 10

Structures buried deep inside the cortex that help to control movement are called the

Accepted Answer

The basal ganglia are structures deep within the cortex that play a crucial role in regulating movement. They are responsible for initiating and coordinating movements, learning new motor skills, and suppressing unwanted movements. The putamen is one of the structures within the basal ganglia, and is specifically involved in controlling movement. The meninges and cerebral ventricles are structures within the brain, but do not play a role in controlling movement.

Question 11

Phineas Gage tragically had a tamping iron propelled through his head. Both left and right sides of the prefrontal cortex were severely damaged. As a result of the accident, Phineas Gage

Accepted Answer

Phineas Gage suffered a change in personality as a result of the severe damage to both left and right sides of his prefrontal cortex.

Question 12

Which of the following is the section of the brain located at the rear of each cerebral hemisphere and contains the visual centres of the brain?

Accepted Answer

The occipital lobe is located at the rear of each cerebral hemisphere and contains the visual centres of the brain, processing visual information from the eyes. The other three options do not contain the visual centres of the brain.

Question 13

The part of the brain dedicated to emotion is called the ________.

Accepted Answer

The answer of The part of the brain dedicated to...

Question 14

Of the following functions, which is NOT controlled by the temporal lobe of the cerebral cortex?

Accepted Answer

The temporal lobe is primarily responsible for processing auditory information, storing memories, and understanding language, but visual processing is mainly controlled by the occipital lobe.

Question 15

Darla was in an automobile accident that resulted in an injury to her brain. Her sense of touch has been affected. Which part of the brain is the most likely site of the damage?

Accepted Answer

The parietal lobes are responsible for processing sensory information from the body, including touch, temperature, and pain sensations. Damage to this area, as in Darla's case, can result in altered tactile perception or loss of sensation.

Question 16

After a head injury, a person reports that she is unable to see, although her eyes are uninjured. A doctor would suspect an injury in the ________ lobe.

Accepted Answer

The occipital lobe is responsible for processing visual information, so damage to this area can result in blindness or visual impairments even if the eyes themselves are uninjured.

Question 17

The ________ regulates and maintains constant internal bodily states such as hunger, thirst, sexual motivation, and body temperature.

Accepted Answer

The answer of The ________ regulates and maintains constant internal...

Question 18

Mary suffered a head injury in a car accident last week. Since that time she is able to speak fluently but has difficulty understanding what is being said to her. Mary may be exhibiting problems associated with ________ area.

Accepted Answer

Wernicke's area is responsible for language comprehension, so Mary's difficulty understanding what is being said to her suggests damage to this area. Broca's area is responsible for speech production, Gall's area is not a known brain area related to language, and Korsakoff's syndrome is characterized by memory deficits rather than language problems.

Question 19

What part of the brain acts as a relay station for incoming sensory information?

Accepted Answer

The thalamus acts as a relay station for incoming sensory information, receiving input from all sensory systems except olfaction and relaying it to the corresponding regions of the cortex for processing. The hypothalamus is involved in regulation of basic functions such as thirst, hunger, and body temperature, while the pituitary gland is an endocrine gland that secretes hormones for various bodily functions. The endocrine system is a collection of glands that produce and secrete hormones to regulate bodily functions.

Question 20

The part of the brain dedicated to emotion is the

Accepted Answer

The limbic system, which includes the hippocampus, amygdala, and hypothalamus, is the part of the brain dedicated to emotion. It is responsible for processing and regulating emotions, as well as certain behaviors and motivations. The endocrine system is a collection of glands that produce hormones, and while hormones can have an effect on emotions, the endocrine system itself is not dedicated to emotion. The reticular activating system is involved in arousal and wakefulness, but not specifically emotion. The lymphatic system is responsible for immune function and the removal of waste from the body and is not related to emotion.
