Nervous System Quiz

What are the two general regions of the nervous system?

• Sympathetic Nervous System and Parasympathetic Nervous System

• Central Nervous System (CNS) and Peripheral Nervous System (PNS)

• Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)

• Hindbrain and Forebrain

Which part of the brain is responsible for balance and movement coordination?

• Medulla

• Pons

• Cerebellum

• Cerebrum

What is the function of the sympathetic nervous system?

• Maintain balance and movement coordination

• Activate the fight or flight response

• Coordinate signals with the rest of the brain

• Regulate breathing, blood pressure, and heart rate

Which cell type in the nervous system helps maintain the blood-brain barrier?

• Neurons

• Glial cells

• Axons

• Dendrites

What is the resting potential of a neuron?

• More positive than its surroundings

• Equal to its surroundings

• More negative than its surroundings

• Depends on the type of neuron

What happens during depolarization in an action potential?

• Sodium ions flood inside the axon

• Potassium ions flood outside the axon

• Sodium ions flood outside the axon

• Potassium ions flood inside the axon

What is the purpose of myelin sheaths in neurons?

• To insulate the axon and assist with signal transfer

• To insulate the cell body

• To insulate the synapse

• To insulate the dendrites

What is the space between two neurons called?

What is the main function of neurotransmitters in the nervous system?

• To carry signals across the synapse

• To insulate the axons of neurons

• To regulate blood pressure and heart rate

• To maintain the resting potential of neurons
