What is the basic structure of a neuron?

Back

A neuron consists of a cell body, dendrites, and an axon.

Front

What is the difference between sensory neurons and motor neurons?

Back

Sensory neurons transmit signals from sensory receptors to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles.
