Parts of the Nervous System Quiz

What are the two major subdivisions of the nervous system?

• Brain and Spinal Cord

• Central Nervous System and Peripheral Nervous System

• Somatic Nervous System and Autonomic Nervous System

• Sympathetic Nervous System and Parasympathetic Nervous System

What is the primary function of the somatic nervous system?

• Relay of sensory and motor information to and from the CNS

• Preparation of the body for stress-related activities

• Control of internal organs and glands

• Returning the body to routine, day-to-day operations

Which type of fibers carry instructions from the CNS to the muscles?

• Efferent fibers

• Parasympathetic fibers

• Afferent fibers

• Sympathetic fibers

What is the role of the autonomic nervous system?

• Transmission of sensory information to the CNS

• Control of voluntary movements

• Control of internal organs and glands

• Coordination of muscle movements

Which division of the autonomic nervous system is involved in preparing the body for stress-related activities?

• Central nervous system

• Sympathetic nervous system

• Parasympathetic nervous system

• Somatic nervous system

What is homeostasis?

• A state of heightened sensory capacity

• A state of equilibrium or balance in biological conditions

• A state of increased heart rate and blood pressure

• A state of glucose release and adrenaline surge

What physiological changes are associated with the fight or flight response?

• Storage of glucose in the form of glycogen

• Pupil constriction and bladder control

• Decreased heart rate and blood pressure

• Increased heart rate and blood pressure

Which system is responsible for returning the body to a relaxed state after a threat has been resolved?

• Central nervous system

• Parasympathetic nervous system

• Somatic nervous system

• Sympathetic nervous system

What is the primary function of sensory neurons?

• Carrying sensory information to the CNS

• Preparing the body for stress-related activities

• Returning the body to routine, day-to-day operations

• Carrying instructions from the CNS to the muscles

What is the effect of the parasympathetic nervous system on the liver after a threat has been resolved?

• Releases glucose

• Stores glucose in the form of glycogen

• Increases heart rate

• Dilates pupils
