Question 1

The lobe of the brain that serves as the "executive control center" for the brain is the ________ lobe.
A) occipital
B) frontal
C) parietal
D) temporal

Accepted Answer

The frontal lobe is responsible for complex cognitive functions such as decision making, problem solving, planning, and controlling behavior, making it the executive control center of the brain.

Question 2

After his last class, Carlos went out to his car to get some books to return to the library. He found that during the day someone had badly smashed his rear bumper. He was furious and began pounding on the hood and shouting obscenities. What area of the brain was guiding his behavior?
A) the hypothalamus
B) the medulla
C) the thalamus
D) the midbrain

A) cerebral cortex
B) medulla
C) cerebellum
D) pons

Accepted Answer

The medulla is the part of the hindbrain that controls vital functions such as breathing, heart rate, and blood pressure. The cerebral cortex is responsible for higher level cognitive processes such as perception, thinking, and decision-making. The cerebellum is responsible for coordinating movement and balance. The pons is involved in regulating sleep and arousal, among other functions.

Question 5

A baby is born with an impairment of his left cerebral hemisphere, but it is not discovered until years later, when certain clues are pieced together. Which of the following is most likely to be one of those clues?
A) He has difficulty identifying colors.
B) He has difficulty perceiving concepts and spatial relationships.
C) He has difficulty learning to read.
D) He has difficulty recognizing people's faces.

Accepted Answer

The left cerebral hemisphere is primarily responsible for language and analytical tasks, including reading. Difficulty learning to read could be a clue pointing to an impairment in the left hemisphere.

A) primary motor cortex
B) association areas
C) primary somatosensory cortex
D) sensory projection areas

Question 8

Which hemisphere of the cerebral cortex is usually dominant in language tasks?
A) the front hemisphere
B) the right hemisphere
C) the rear hemisphere
D) the left hemisphere

Accepted Answer

The left hemisphere is usually dominant in language tasks. This is known as the "left hemisphere specialization for language." Studies have shown that language processing, including speech production and comprehension, reading, and writing, predominantly occurs in the left hemisphere of the cerebral cortex in most people.

Question 9

Anesthetics work primarily by shutting down the ________.
A) endocrine system
B) reticular formation
C) limbic system
D) dopamine receptor sites

Accepted Answer

Anesthetics work primarily by shutting down the reticular formation, a network of neurons in the brainstem that regulates arousal and consciousness. By depressing this area, anesthetics can induce unconsciousness and prevent the brain from processing pain signals.

Question 10

The limbic system is responsible for ________.
A) controlling learning and emotional behavior
B) connecting the brain to the rest of the body
C) filtering incoming messages to the brain
D) fighting disease organisms that attempt to infect the brain

Accepted Answer

The limbic system is a group of structures in the brain that are responsible for regulating emotions, learning, and memory. It includes the amygdala, hippocampus, and hypothalamus, among other structures.

Question 11

After an industrial accident in which George fell from a scaffold and hit his head, he has had trouble following directions or completing his normal work tasks. He is also apathetic, although he has periods of boastfulness and silliness. The damaged part of his brain is probably the ________ lobes.
A) occipital
B) parietal
C) temporal
D) frontal

Accepted Answer

The frontal lobes are responsible for executive functions such as planning, problem-solving, decision-making, and following instructions. Damage to this area can result in apathy, impulsivity, and difficulty with tasks requiring these executive functions.

Question 12

Corey was in an automobile accident that resulted in an injury to her brain. She now has difficulty reading road maps and telling other people how to get somewhere. She has most likely suffered an injury to her ________ lobe.
A) occipital
B) temporal
C) frontal
D) parietal

Accepted Answer

The parietal lobe is responsible for processing spatial information and navigation. Injuries to this lobe can result in difficulty with tasks such as reading maps and giving directions.

Question 13

Messages from the sense receptors are registered in those areas of the brain called the ________.
A) hemispheric lateralization areas
B) primary somatosensory cortex
C) motor projection areas
D) association areas

Accepted Answer

Messages from sense receptors are first registered in the primary somatosensory cortex, which is responsible for processing sensory information from the body.

Question 14

"Split brain" patients are patients who have had ________.
A) their cerebellum split in the middle
B) their brain stem cut down the middle
C) their corpus callosum cut
D) a prefrontal lobotomy

Accepted Answer

Split brain patients have had their corpus callosum cut, which is the bundle of fibers that connects the two hemispheres of the brain. This procedure is often done to treat severe epilepsy.

Question 15

The area of the frontal lobe that is crucial in our ability to talk is ________ area.
A) Gall's
B) Broca's
C) Korsakoff's
D) Wernicke's

Accepted Answer

Broca's area, which is located in the left frontal lobe, is crucial for language production and speech formation. Gall's area and Korsakoff's area are not related to language processing, and Wernicke's area is associated with language comprehension rather than production.

Question 16

The intricate network of folds that line the outer surface of the cerebral cortex, allowing it to fit inside the skull, are called ________.
A) convolutions
B) sensory projection areas
C) association areas
D) motor projections

Accepted Answer

The intricate network of folds that line the outer surface of the cerebral cortex are called convolutions. These convolutions allow for a greater surface area of the cortex to fit inside the limited space of the skull.

Question 17

The ________ is believed to be the earliest part of the brain to evolve.
A) midbrain
B) hindbrain
C) forebrain
D) limbic system

Accepted Answer

The hindbrain is believed to be the earliest part of the brain to evolve. This part of the brain is responsible for regulating basic bodily functions, such as breathing and heartbeat, which are necessary for survival.

Question 18

Corey was in an automobile accident that resulted in an injury to her brain. She now has difficulty with her hearing and her ability to recognize faces. The part of her brain most likely injured was her ________ lobe.
A) frontal
B) temporal
C) occipital
D) parietal

Accepted Answer

The temporal lobe is responsible for processing auditory information and playing a role in facial recognition, therefore, it is the most likely lobe to be injured in this situation.

Question 19

The cerebellum ________.
A) controls blood pressure
B) relays messages from the sensory receptors
C) coordinates actions so that movements are efficient
D) governs hunger, thirst, and body temperature

Accepted Answer

The cerebellum is responsible for coordinating movements and ensuring they are performed efficiently. It does not control blood pressure or govern physiological needs like hunger, thirst, and body temperature, nor does it relay messages from the sensory receptors.

Question 20

A college student is having difficulty staying awake during the day and sleeping through the night. This difficulty is most likely due to problems in the ________.
A) cerebellum
B) basal ganglia
C) pons
D) substantia nigra

Accepted Answer

The pons is involved in regulating sleep and arousal. Difficulties in this area can lead to disrupted sleep patterns and difficulty staying awake during the day. The cerebellum and basal ganglia are primarily involved in motor coordination and movement, while the substantia nigra is involved in motor control and is primarily associated with Parkinson’s disease.
