Organize the following list of nervous system elements by their classifications as CNS or PNS elements: oligodendrocytes, thermoreceptors (nerves that sense temperature), interneurons, satellite cells, brain, motor neurons.
A)CNS thermoreceptors, satellite cells, brain; PNS oligodendrocytes, interneurons, motor neurons
B)CNS satellite cells, brain, oligodendrocytes; PNS thermoreceptors, motor neurons, interneurons
C)CNS interneurons, satellite cells, motor neurons; PNS brain, oligodendrocytes, theromoreceptors
D)CNS brain, oligodendrocytes, interneurons; PNS thermoreceptors, satellite cells, motor neurons

Question

Quizplus · Accepted Answer

The brain and oligodendrocytes are clearly CNS elements, while thermoreceptors and satellite cells are characteristic of the PNS. Interneurons can be either CNS or PNS elements, but since motor neurons are located in the spinal cord (which is part of the CNS), they are also classified as CNS elements. Therefore, choice D is the best answer.
