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 helping us perceive our environment by detecting stimuli such as light, sound, touch, taste, and smell. Each type of sensory neuron is designed to respond to specific types of stimuli, allowing us to experience the world around us. These neurons convert physical signals into electrical impulses, which are then sent to the brain for processing. For example, when you touch something hot, sensory neurons in your skin send signals to your brain, prompting a quick reaction to avoid injury. This process is essential for survival and helps us interact with our surroundings effectively.
