Nervous System Worksheet Quiz

Which of the following is NOT a function of the nervous system?

• Sensory – Receives information from the environment.

• Integrative – Processes and interprets sensory input.

• Digestive – Breaks down food for energy.

• Motor – Responds by activating muscles or glands.

What are the two main divisions of the nervous system?

• Central Nervous System and Digestive System

• Central Nervous System and Peripheral Nervous System

• Peripheral Nervous System and Circulatory System

• Autonomic Nervous System and Respiratory System

Which part of the nervous system is responsible for voluntary control of skeletal muscles?

• Autonomic Nervous System

• Somatic Nervous System

• Sympathetic Nervous System

• Parasympathetic Nervous System

Explain the difference between the sympathetic and parasympathetic divisions of the autonomic nervous system.

• Sympathetic is for “rest and digest,” parasympathetic is for “fight or flight.”

• Sympathetic is for “fight or flight,” parasympathetic is for “rest and digest.”

• Both control voluntary muscle movement.

• Both are part of the central nervous system.

A student claims that the neuron is the basic unit of the nervous system. Use evidence from the study guide to support or refute this claim.

• Support, because the study guide states that the neuron is the basic unit of the nervous system.

• Refute, because the study guide says the brain is the basic unit.

• Refute, because the study guide says the spinal cord is the basic unit.

• Support, because the study guide says the neuron is only found in the digestive system.

Which part of a neuron is responsible for receiving signals?

• Axon

• Dendrites

• Synapse

• Axon Terminals

What is the main function of Schwann cells in the nervous system?

• Immune defense

• Make myelin in PNS

• Connect neurons to blood supply

• Line brain/spinal cord cavities

Which neurotransmitter is primarily associated with muscle movement?

• Dopamine

• Serotonin

• Acetylcholine (ACh)

• Norepinephrine

Explain how myelin sheaths affect nerve impulses and why this is important for nervous system function.

• They slow down nerve impulses, making communication less efficient.

• They have no effect on nerve impulses.

• They speed up nerve impulses, allowing for faster communication between neurons.

• They block nerve impulses from traveling.

A patient is experiencing issues with mood, sleep, and appetite. Which neurotransmitter is most likely involved, and what evidence supports your answer?

• Dopamine, because it is involved in pleasure and movement.

• Serotonin, because it regulates mood, sleep, and appetite.

• Norepinephrine, because it is involved in stress response.

• Acetylcholine, because it controls muscle movement.
