What are nerves primarily made up of?

Nerves are primarily made up of a bundle of neurons. Neurons are specialized cells that transmit electrical signals throughout the nervous system, facilitating communication between different parts of the body. Each neuron is made up of a cell body, dendrites, and an axon. When grouped together to form a nerve, these neurons work collectively to relay sensory information and coordinate motor functions.

The significance of neurons in forming nerves lies in their ability to send and receive signals efficiently. In the context of animal management and biological systems, understanding the role of neurons is vital for comprehending how animals perceive their environment and respond to stimuli.

While axons are indeed part of neurons—the long projections that conduct impulses away from the neuron's body—the correct emphasis is on the broader structure, which includes both the cell bodies and dendrites of multiple neurons grouped together. Therefore, the accurate understanding of a nerve's composition points to a collection of neurons rather than just focusing on axons alone.
