Example Questions

Example Question #71 : Biology

The limbic system regulates basic emotions, drives, and memory. Which answer choice best describes the structures included in this system?

Possible Answers:

Hippocampus, amygdala, temporal lobe, hypothalamus

Hippocampus, cerebellum, thalamus, hypothalamus

Medulla, amygdala, thalamus, hypothalamus

Hippocampus, amygdala, thalamus, hypothalamus

Hippocampus, cerebellum, thalamus, tectum

Correct answer:

Hippocampus, amygdala, thalamus, hypothalamus

Explanation:

The limbic system is commonly thought of as the hippocampus (memory), amygdala (emotion), thalamus (sensory information), and hypothalamus (basic drives, homeostasis).

Each other answer choice had one wrong structure in the list. The temporal lobe controls hearing and language, the cerebellum controls basic motor skills, the tectum controls orientation in a new environment, and the medulla helps control heart beat and respiration. 

Example Question #72 : Biology

Which part of the hindbrain makes up  fo the brain's volume and has two hemispheres?

Possible Answers:

Pons

Cerebellum

Medulla

Spinal cord

Correct answer:

Cerebellum

Explanation:

The cerebellum resembles the much larger cerebrum. It makes up  of the brain's volume and has two hemispheres. The cerebelum's primary function is to regulate muscle control and activity.

Example Question #71 : Biology

Which of these is not part of the peripheral nervous system?

Possible Answers:

Sympathetic nervous system

Parasympathetic nervous system

Somatic nervous system

Spinal cord

Correct answer:

Spinal cord

Explanation:

The central nervous system is composed of the brain and spinal cord. The peripheral nervous system is composed of the somatic and autonomic nervous systems. The autonomic nervous system is composed of the sympathetic and parasympathetic nervous systems. 

Example Question #23 : Brain And Nervous System

When a person just so happens to be faced with an angry bear, which nervous system is in control?

Possible Answers:

Sympathetic nervous system

Somatic nervous system

Central nervous system

Parasympathetic nervous system

Correct answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system prepares the body for action and mobilizes energy resources. This is considered the flight or fight reaction. 

Example Question #24 : Brain And Nervous System

Which structure is not part of the hindbrain?

Possible Answers:

Medulla

Corpus callosum

Pons

Cerebellum

Correct answer:

Corpus callosum

Explanation:

The hindbrain is composed of pons, medulla, spinal cord, reticular formation, and cerebellum. The corpus callosum is part of the forebrain. 

Example Question #1371 : Ap Psychology

The reticular formation is responsible for which function?

Possible Answers:

Control center for the heart beat

Arousal system

Hunger and thirst

Skilled movement

Correct answer:

Arousal system

Explanation:

The reticular formation is responsible for the arousal system but not heartbeat, movement, hunger and thirst. 

Example Question #81 : Biology

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

Possible Answers:

Storing new information

Thirst and hunger

Unconscious motor actions

Emotions

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:

Autonomic nervous system 

Parasympathetic nervous system

Central nervous system

Sympathetic nervous system

Somatic 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.
