Peripheral Nervous System Quiz

What are the two functional subdivisions of the Peripheral Nervous System (PNS)?

• Central and Peripheral Division

• Sensory (Afferent) and Motor (Efferent) Division

• Autonomic and Somatic Division

• Sympathetic and Parasympathetic Division

What is the role of the Sensory (Afferent) Division of the PNS?

• It sends out information from the brain to muscles and glands.

• It processes sensory information in the brain.

• It receives sensory stimuli to send back to the CNS/brain.

• It controls voluntary muscle movements.

What type of information do somatic sensory fibers carry?

• Information from the brain to the muscles

• Information from the visceral organs

• Information from the skin, skeletal muscles, and joints

• Information from the sensory organs to the spinal cord

What is the function of the Motor (Efferent) Division of the PNS?

• It receives sensory information from the body.

• It sends out information from the brain to effector organs like muscles and glands.

• It processes motor commands in the brain.

• It controls the involuntary actions of the autonomic nervous system.

What type of movements do somatic motor nerve fibers control?

• Involuntary movements

• Reflexive movements

• Voluntary movements

• Automatic movements

Which neurotransmitter is released to stimulate contractions in the Somatic Nervous System?

• Dopamine

• Serotonin

• Acetylcholine (ACh)

• Norepinephrine

Where does the neuron's cell body start in the Somatic Nervous System?

• Peripheral Nervous System (PNS)

• Central Nervous System (CNS)

• Autonomic Nervous System (ANS)

• Enteric Nervous System (ENS)

Where do nerve impulses travel down to reach the neuromuscular junction in the Somatic Nervous System?

• The neuron's dendrites

• The neuron's myelin sheath

• The neuron's axon

• The neuron's cell body

What type of muscle fibers does the Autonomic Nervous System innervate?

• Skeletal muscles

• Cardiac and smooth muscles

• Cardiac and skeletal muscles

• Smooth muscles only

Which neurotransmitter is released in the sympathetic nervous system?

• Dopamine

• Serotonin

• Acetylcholine (ACh)

• Norepinephrine (NE)
