What is a "sensory neuron"?

A sensory neuron, also known as an afferent neuron, is a specialized nerve cell that carries sensory information from the peripheral nervous system to the central nervous system. These neurons have specialized receptors at their endings that detect various stimuli such as touch, temperature, pain, pressure, and chemical changes. Upon receiving a sensory stimulus, the sensory neuron generates electrical impulses that travel along its long, slender axon toward the spinal cord or brain, where the information is processed and interpreted. Sensory neurons play a vital role in our ability to sense and perceive the world around us, allowing us to experience sensations and react accordingly.
