Example Questions

Example Question #81 : Biology

Which nervous system contains an autonomic and somatic division?

Possible Answers:

Sympathetic nervous system 

Enteric nervous system 

Parasympathetic nervous system 

Peripheral nervous system 

Central nervous system 

Correct answer:

Peripheral nervous system 

Explanation:

The nervous system is first subdivided into two large branches: the peripheral and central nervous systems. The central nervous system is composed of the brain and the spine and the peripheral is slightly more complicated. It can be subdivided into the autonomic (controlling internal organs and glands) and the somatic (skeletal). The enteric nervous system does not play a part in this overall nervous system. Instead, it is responsible for gastrointestinal processes. 

Example Question #32 : Brain And Nervous System

Which nervous system subdivision is responsible for counteracting the "fight or flight" response?

Possible Answers:

Sympathetic nervous system

Parasympathetic nervous system

Somatic nervous system

Autonomic nervous system

Central nervous system 

Correct answer:

Parasympathetic nervous system

Explanation:

The sympathetic nervous system is responsible for initiating the fight or flight response. Conversely, the parasympathetic nervous system is responsible for ending the response. The parasympathetic nervous system will oppose the effects via conserving energy, lowering blood pressure and heart rate, and lowering your blood sugar. 

Example Question #81 : Biology

Which of the following choices is not part of the somatic nervous system?

Possible Answers:

Sense receptors in the eyes, ears, and skin

Motor nerves

Cardiac muscle

Sense receptors in the nose and tongue

Correct answer:

Cardiac muscle

Explanation:

The somatic nervous system makes it possible for an organism to sense and move in its environment. This system is primarily comprised sensory receptors—found in eyes, ears, nose, tongue, and skin—and motor nerves that relay information from the central nervous system. The nerves in the somatic nervous system are usually under conscious control. Unconscious control such as cardiac muscle movement is regulated by the autonomic nervous system. Nerves that transmit messages from the central nervous system to glands, cardiac muscle, and smooth muscle are part of the autonomic nervous system. 

Example Question #31 : Brain And Nervous System

Which area located in the temporal lobe adversely affects speech when damaged?

Possible Answers:

Primary auditory cortex

Wernicke's area

Somatosensory cortex

Primary visual cortex

Correct answer:

Wernicke's area

Explanation:

Wernicke's area is the language area that is responsible for comprehending spoken word as well as formulating written and spoken language. A person with damage to this area could develop speech that is incomprehensible. This particular speech disorder is known as Wernicke's aphasia. 

Example Question #82 : Biology

Which of the following choices is best described as a sympathetic response?

Possible Answers:

Relaxation of the bladder

Depression of heartbeat

Contraction of the bladder

Constriction of the pupils

Correct answer:

Relaxation of the bladder

Explanation:

The sympathetic nervous system mobilizes the body during emergencies. These responses include the dilation of pupils, inhibition of salivary glands, relaxation of bronchi, acceleration of heartbeat, inhibition of digestive activity, the release of glucose from the liver, relaxation of the bladder, and inhibition of sexual arousal.

Example Question #1381 : Ap Psychology

Which of the following choices is best described as a parasympathetic response?

Possible Answers:

Inhibition of the salivary glands

Acceleration of heartbeat

Constriction of the pupils

Dialation of the pupils

Correct answer:

Constriction of the pupils

Explanation:

After an emergency the parasympathetic nervous system depresses the heightened bodily responses to normal levels. These responses include the constriction of pupils, stimulation of salivary glands, constriction of bronchi, slowing of heartbeat, stimulated digestive activity, stimulated gall bladder activity, contraction of the bladder, and the stimulation of sexual arousal. 

Example Question #33 : Brain And Nervous System

What part of the parietal lobe is the site that registers touch, pressure, temperature, and pain in the cerebral cortex?

Possible Answers:

Somatosensory cortex

Primary visual cortex

Motor cortex

Broca's area

Correct answer:

Somatosensory cortex

Explanation:

The somatosensory cortex is the site that registers touch, pressure, temperature, and pain in the cerebral cortex. This area is also responsible for awareness associated with bodily movement and position.

Example Question #31 : Brain And Nervous System

Which of the following choices correctly identifies the four lobes that comprise the cerebral hemisphere?

Possible Answers:

Frontal lobe, parietal lobe, occipital lobe, and audio lobe

Frontal lobe, parietal lobe, occipital lobe, and temporal lobe

Frontal lobe, hind lobe, occipital lobe, and temporal lobe

Frontal lobe, parietal lobe, vision lobe, and temporal lobe

Correct answer:

Frontal lobe, parietal lobe, occipital lobe, and temporal lobe

Explanation:

There are two cerebral hemispheres in the human brain. Each cerebral hemisphere is divided into four lobes. These four lobes include the following: frontal lobe, parietal lobe, occipital lobe and temporal lobe. 

Example Question #31 : Brain And Nervous System

The motor cortex is located in which of the following lobes of the cerebral hemisphere?

Possible Answers:

Temporal lobes

Occipital lobes

Parietal lobes

Frontal lobes

Correct answer:

Frontal lobes

Explanation:

The frontal lobes contain the motor cortex, Broca's area, and frontal association areas. The right motor cortex is responsible for movement on the left side of the body and the left motor cortex is responsible for movement on the right side of the body. 

Example Question #40 : Brain And Nervous System

Which area in the frontal lobe directs the muscle movement patterns that produce speech sounds?

Possible Answers:

Motor cortex

Speech area

Broca's area

Frontal association area

Correct answer:

Broca's area

Explanation:

Broca's area is the area in the frontal lobe that directs the muscle movement patterns responsible for producing speech sounds. When a person suffers from Broca's aphasia they often know what they want to say but physically can not say it.
