Example Questions

Example Question #21 : Brain And Nervous System

The substantia nigra is responsible for which of the following functions?

Possible Answers:

Emotions

Storing new information

Unconscious motor actions

Thirst and hunger

Correct answer:

Unconscious motor actions

Explanation:

The substantia nigra is responsible for unconscious motor actions. Emotions, storing new information and thirst and hunger are functions that happen in the forebrain. 

Example Question #81 : Biology

The motor cortex is located in which area of the brain?

Possible Answers:

Left temporal lobe

Right temporal lobe

Frontal lobe

Occipital lobe

Parietal lobe

Correct answer:

Frontal lobe

Explanation:

The motor cortex is located in the back of the frontal lobe. It is the area of the frontal lobe responsible for voluntary movement.

Example Question #81 : Biology

Which of the following is not a neuron type that is found in the nervous system?

Possible Answers:

Efferent neurons 

Afferent neurons

Interneurons 

Sensory neurons 

Sympathetic neurons

Correct answer:

Sympathetic neurons

Explanation:

Sympathetic neurons are fictitious and not found in the nervous system. Afferent neurons are synonymous to sensory neurons. They are responsible for sending information in the form of a stimulus signal to the interneurons. The interneurons translate the stimulus so that information may be passed to the efferent or motor neurons. In other words, sensory neurons receive and transmit information to interneurons that then relay these messages to the motor neurons.

Example Question #21 : Brain And Nervous System

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

Possible Answers:

Central nervous system

Parasympathetic nervous system

Sympathetic nervous system

Somatic nervous system

Autonomic nervous system 

Correct answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system is responsible for arousal and energy expenditure. When faced with an alarming or challenging situation, this nervous system will act and cause the following physiological responses: accelerated heart beat, increase in blood pressure, a slow down in digestion, and initiation of perspiration. These characteristics compose the "fight or flight" response.

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 #81 : Biology

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

Possible Answers:

Parasympathetic nervous system

Autonomic nervous system

Central nervous system 

Sympathetic nervous system

Somatic 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.
