While batting, a baseball player is struck in the ribs by a pitch. Place the following components of the player's pain pathway in the chronological order as they contribute to the player's sensation of pain. Use all the options.
 
  A) Thalamus
  B) Dorsal root ganglion body
  C) Dorsal root ganglion periphery
  D) Axon
  E) Cerebral cortex

Question 2

The nurse knows which of the following phenomena listed below is an accurate statement about axonal transport?
 
  A)
  Anterograde and retrograde axonal transport allow for the communication of nerve impulses between the neuron and the central nervous system (CNS).
  B)
  Materials can be transported to the nerve terminal by either a fast or slow component.
  C)
  The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.
  D)
  Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.

Answer to Question 1

Ans:
C, B, D, A, E

Feedback:

All somatosensory information from the limbs and trunk shares a common class of sensory neurons called dorsal root ganglion neurons. Somatosensory information from the face and cranial structures is transmitted by the trigeminal sensory neurons, which function in the same manner as the dorsal root ganglion neurons. The cell body of the dorsal root ganglion neuron, its peripheral branch (which innervates a small area of periphery), and its central axon (which projects to the CNS) communicate with the thalamus, which in turn communicates with the cerebral cortex using third-order neurons.

Answer to Question 2

Ans:
B

Feedback:

The bidirectional axonal transport system allows for the transport of molecular materials (as opposed to electrical impulses); anterograde transport has both slow and fast components.

YES! Correct, THANKS for helping me on my review
