FINAL EXAM CHAPTER 14: PERIPHERAL NERVOUS SYSTEM (PNS) QUESTIONS | PRACTICE
QUESTIONS, ANSWERS & STUDY GUIDE 2026/2027
CNS and PNS - correct answer ✔✔What are the two main subdivisions of the nervous system?
brain and spinal cord - correct answer ✔✔What are the components of the CNS?
nerves and ganglia - correct answer ✔✔What are the components of the PNS?
afferent/sensory= signal toward CNS
efferent/motor= signal away from CNS - correct answer ✔✔Briefly differentiate between
afferent and efferent divisions of the PNS.
somatic sensory= outer-tube
visceral sensory= inner-tube - correct answer ✔✔Briefly differentiate between somatic senses
and visceral senses.
somatic motor= outer-tube
visceral motor= inner-tube - correct answer ✔✔Briefly differentiate between somatic motor
and visceral motor.
sensory= signals toward CNS
motor= signals coming from (going away from) the CNS - correct answer ✔✔Differentiate
between sensory receptors and motor endings with respect to the CNS.
skeletal= voluntary
smooth= involuntary
, cardiac= involuntary - correct answer ✔✔Differentiate between motor innervation of skeletal
muscle, smooth muscle, and cardiac muscle.
nerve= collection of nerve fibers
nerve fibers= long axons
neurons= nerve cells - correct answer ✔✔Differentiate between nerve, nerve fiber, and neuron.
cranial= 12 pairs associated with the brain
spinal= 31 pairs associated with the spinal cord - correct answer ✔✔Differentiate between
cranial nerves and spinal nerves.
areas of concentrated cell bodies wrapped in connective tissue - correct answer ✔✔What are
ganglia?
dorsal root ganglion - correct answer ✔✔Name a common type of ganglion associated with
spinal nerves.
exteroceptor - correct answer ✔✔Would your retina be considered an exteroceptor, an
interoceptor, or a proprioceptor?
photoreceptor - correct answer ✔✔Would your retina be considered a mechanoreceptor,
thermoreceptor, chemoreceptor, photoreceptor, or nociceptor?
proprioceptors (location)
proprioceptors (structure) - correct answer ✔✔If you circumduct your digit II with your eyes
closed, you still know its location in space because of the actions of which peripheral sensory
receptor based on location? What about based on structure?
