 Nerve cell that converts environmental stimuli into corresponding internal stimuli |
Sensory neurons, also known as afferent neurons, are in the nervous system which convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials.1 This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal root ganglia of the spinal cord.2
The sensory information travels on the afferent nerve fibers in a sensory nerve, to the brain via the . Spinal nerves transmit external sensations via sensory nerves to the brain through the spinal cord. The stimulus can come from outside the body, or inside the body.
