Select the statement that is most correct.
A) Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
B) The cell bodies of afferent ganglia are located in the spinal cord.
C) The dorsal root ganglion is a motor-only structure.
D) Ganglia are collections of neuron cell bodies in the spinal cord that are associated with efferent fibers.

Question

Quizplus · Accepted Answer

Ganglia associated with afferent nerve fibers contain the cell bodies of sensory neurons. This is because afferent fibers are responsible for carrying sensory information from the periphery to the central nervous system, and the cell bodies of sensory neurons are located in the ganglia associated with these fibers. Option B is incorrect because the cell bodies of afferent neurons are not located in the spinal cord but rather in the ganglia outside of the spinal cord. Option C is incorrect because the dorsal root ganglion contains the cell bodies of both sensory and motor neurons. Option D is incorrect because ganglia are collections of neuron cell bodies that are associated with both afferent and efferent fibers, not just efferent fibers.
