Question

Quizplus · Accepted Answer

A nerve is a bundle of neuronal fibers (axons and dendrites) outside the central nervous system, connecting different regions of the body to the spinal cord and brain. These fibers can be sensory, motor or mixed, depending on their direction of information transmission. Option B is incorrect because a nerve is not a single extension of a neuron but rather a bundle of extensions of many neurons. Option C is incorrect because the term "nerve" specifically refers to structures outside the central nervous system. Option D is incorrect because nerve cell bodies are part of ganglia, not nerves. Option E is incorrect because there is no minimum length requirement for a fiber to be considered a nerve.
