Question

multiple choice question
what is a nerve?
the axon of a single neuron
a support cell of the nervous system
a bundle of axons
a mass of cell bodies

Explanation:

To determine the correct answer, we analyze each option:

• "The axon of a single neuron": A nerve is not just a single axon; it involves multiple axons. Eliminate this.
• "A support cell of the nervous system": Support cells (like glial cells) are not nerves. Nerves are related to axons for signal transmission. Eliminate this.
• "A bundle of axons": Nerves are indeed bundles of axons (from multiple neurons) that transmit electrical signals. This matches the definition.
• "A mass of cell bodies": A mass of cell bodies is more related to a ganglion, not a nerve. Eliminate this.

Answer:

C. A bundle of axons
