Primary sensory neurons carry action potentials from sensory receptors through nerves.

These neurons are responsible for transmitting sensory information from the peripheral nervous system to the central nervous system, where the information is processed and interpreted. Primary sensory neurons have specialized receptor endings that detect various stimuli such as touch, temperature, pain, and proprioception. These neurons have long axons that extend from the receptor endings to the spinal cord or brain, where they synapse with secondary sensory neurons. The action potentials generated by the primary sensory neurons are then relayed to the brain, where they are perceived as sensory experiences.
