What are the main components of a neuron?

The main components of a neuron include the cell body, dendrites, and an axon.

The cell body, also known as the soma, contains the nucleus and is responsible for the overall metabolic functions of the neuron. Dendrites are tree-like structures that extend from the cell body and are primarily responsible for receiving signals from other neurons. They play a crucial role in the communication between neurons by gathering input and transmitting it to the cell body. The axon is a long, thin structure that carries electrical impulses away from the cell body towards other neurons or target cells, allowing for the transmission of signals over distance.

This combination of components is fundamental for the neuron's function as an information-processing unit in the nervous system. While other options include different neuron components, they either miss critical elements or mix components that do not accurately represent the standard structure of a neuron.
