Sensory neurons are specialized nerve cells that transmit sensory information from the body's sensory receptors to the central nervous system. They play a crucial role in processing stimuli such as touch, temperature, pain, and taste. These neurons convert physical signals into electrical impulses, allowing the brain to interpret and respond to the environment. There are different types of sensory neurons, each responsible for specific senses. For example, photoreceptors in the eyes detect light, while mechanoreceptors in the skin respond to pressure and vibration. Together, these neurons help us perceive and interact with the world around us.
