Question 2

The structure in the center of the forebrain that relays sensory information is called the __________.
A)medulla
B)hypothalamus
C)pons
D)thalamus

Accepted Answer

The thalamus is the structure in the center of the forebrain that functions as a relay station for sensory information. It processes and redirects sensory information to the cerebral cortex for further processing and interpretation. The medulla, pons, and hypothalamus are located in the brainstem and are involved in other functions such as regulating basic bodily functions like breathing, heart rate, and hormone secretion.

Question 3

The part of the brain which controls breathing,heartbeat,and posture is the
A)pituitary gland.
B)neocortex.
C)hypothalamus.
D)medulla.

Accepted Answer

The medulla, located in the brainstem, is responsible for controlling essential functions such as breathing, heart rate, and posture. The pituitary gland is responsible for releasing hormones, the neocortex is responsible for complex thinking and decision making, and the hypothalamus plays a role in regulating bodily functions such as hunger, thirst, and body temperature, but not specifically breathing, heart rate, and posture.

Question 4

Which of the following is NOT one of the three distinct parts of the brain?
A)hindbrain
B)lateralbrain
C)midbrain
D)forebrain

Accepted Answer

The three distinct parts of the brain are the hindbrain, midbrain, and forebrain. "Lateralbrain" is not a recognized area of the brain.

Question 5

The brain is part of the
A)nervous system.
B)endocrine system.
C)thalamic system.
D)cranial system.

Accepted Answer

The brain is part of the nervous system, which is responsible for transmitting signals throughout the body and controlling bodily functions.

Question 6

Eating,drinking,sexual behavior,temperature control,and sleeping are strongly influenced by the __________.
A)medulla
B)cerebral cortex
C)thalamus
D)hypothalamus

Accepted Answer

The hypothalamus plays a crucial role in regulating various bodily functions including eating, drinking, sexual behavior, temperature control, and sleeping. It receives signals from the body and triggers appropriate responses to maintain homeostasis. The medulla and thalamus are involved in other functions such as controlling breathing and relaying sensory information, while the cerebral cortex is mainly responsible for higher cognitive functions.

Question 7

A young woman recovering from a blow to her head finds she has great difficulty maintaining her balance and coordinating her movements.Injury to which part of her brain is likely to be causing her difficulties?
A)cerebellum
B)medulla
C)cerebral cortex
D)thalamus

Accepted Answer

The cerebellum is responsible for coordinating movements and maintaining balance, which is consistent with the symptoms described in the scenario. The medulla is responsible for regulating basic functions such as breathing and heart rate. The cerebral cortex is responsible for higher level functions such as perception, thinking, and language. The thalamus is responsible for relaying sensory information to the cerebral cortex. None of these brain regions are directly responsible for maintaining balance and coordination.

Question 8

The human brain
A)weighs about 6 to 7 ounces.
B)is composed of several thousand neurons.
C)is half nerve tissue and half motor tissue.
D)none of the above.

Accepted Answer

The human brain weighs about 3 pounds (not 6 to 7 ounces), contains approximately 86 billion neurons (not several thousand), and is composed of various types of tissue, not specifically half nerve and half motor tissue.

Question 9

The part of the brain responsible for emotional behavior and regulating the nervous system in times of stress is the _________.
A)medulla
B)cerebellum
C)thalamus
D)hypothalamus

Accepted Answer

The hypothalamus is responsible for regulating the nervous system in times of stress and also plays a key role in emotional behavior. It controls the release of stress hormones such as cortisol and adrenaline, which help the body respond to stress. The medulla regulates important autonomic functions such as heart rate and breathing, while the cerebellum is involved in coordinating movement and balance. The thalamus acts as a relay center for sensory information.

Question 10

The brain:
A)is an integrated system within itself.
B)controls the endocrine system.
C)is part of the nervous system.
D)All of the above.

Accepted Answer

The brain is not only part of the nervous system but also an integrated system within itself that controls the endocrine system. Therefore, all of the above options are correct.

Question 11

Garcia is having great difficulty controlling his appetite.All he wants to do is eat and no matter how much he eats,he is still hungry.His weight is approaching 400 pounds and he still constantly wants to eat.His physician says the problem is due to a disorder in a specific center of the brain.That brain center is most likely the __________.
A)medulla
B)cerebral cortex
C)thalamus
D)hypothalamus

Accepted Answer

The hypothalamus is responsible for regulating appetite and satiety. If Garcia is constantly hungry despite eating excessive amounts of food and gaining weight, it suggests a dysfunction in his hypothalamus, leading to an increased appetite and disrupted satiety signaling. The other options (medulla, cerebral cortex, thalamus) are not directly involved in appetite regulation.

Question 12

Damage to the medulla can seriously impair one's ability to
A)sing.
B)write.
C)breathe.
D)urinate.

Accepted Answer

The medulla is responsible for controlling vital functions such as breathing, heart rate, and blood pressure. Damage to the medulla can result in breathing difficulties and even respiratory failure. While the medulla may also have some involvement in other functions such as singing (which involves control of the larynx) and urination, impairments in these functions would not be as life-threatening as those related to breathing. Writing is primarily controlled by areas of the cerebral cortex, which is not directly affected by damage to the medulla.

Question 13

The spinal cord:
A)connects the brain to the rest of the body.
B)is composed of nerve tissue.
C)can work independently of the brain.
D)all of the above

Accepted Answer

The spinal cord connects the brain to the rest of the body, is composed of nerve tissue, and is capable of working independently of the brain to carry out reflex actions. Therefore, all of the given options are correct.

Question 14

The cerebellum __________.
A)controls blood pressure
B)is involved in emotional behavior
C)coordinates actions so that movements are efficient
D)relays messages from the sensory receptors

Accepted Answer

The cerebellum is responsible for the coordination of movements and ensuring their efficiency. It does not control blood pressure, emotional behavior or relay messages from sensory receptors.

Question 15

The left and right cerebral hemispheres are connected by the:
A)occipital lobe.
B)pons.
C)sylvian fissure.
D)corpus callosum.

Accepted Answer

The corpus callosum connects the left and right cerebral hemispheres and allows for communication and coordination between them. The other options listed are structures or features of the brain, but they do not directly connect the hemispheres.

Question 16

The medulla,pons,and cerebellum are all part of the:
A)midbrain.
B)hindbrain.
C)spinal cord.
D)forebrain.

Accepted Answer

The medulla, pons, and cerebellum are all located in the hindbrain, which is responsible for basic life-sustaining functions such as breathing, heart rate, and coordination.

Question 17

The two major divisions of the central nervous system are:
A)left and right hemispheres.
B)the brain and autonomic systems.
C)brain and spinal cord.
D)peripheral and autonomic systems.

Accepted Answer

The central nervous system is divided into two main parts: the brain and the spinal cord. The brain is responsible for processing and interpreting information from the senses and directing the body's responses. The spinal cord is responsible for transmitting information between the brain and the rest of the body. The other options are incorrect because they do not accurately reflect the major divisions of the central nervous system.

Question 18

The part of the hindbrain that controls such things as breathing,heart rate,and blood pressure is the __________.
A)cerebral cortex
B)pons
C)medulla
D)cerebellum
