Meaning and Definition
A nerve cell that transmits information from a sensory receptor (like in the skin or eye) to the central nervous system.
The primary unit of the afferent nervous system responsible for converting external stimuli (e.g., touch, temperature, sound) into electrical signals that are sent to the brain or spinal cord for processing. It is sometimes metaphorically extended in non-technical language to describe a source of input or information.

For most sensory neurons in the body, their cell bodies are located in clusters called dorsal root ganglia, just outside the spinal cord.
When you touch a hot surface, sensory neurons in your fingertip immediately send an electrical signal to your spinal cord and brain, leading to the perception of heat and pain.
A motor (or efferent) neuron. It carries commands from the central nervous system to muscles or glands to produce an action, like moving your hand away from the heat.
A nerve cell that transmits information from a sensory receptor (like in the skin or eye) to the central nervous system.
