Sensory receptors are specialized cells that detect and respond to various stimuli from the environment. They convert physical energy, such as light, sound, or touch, into electrical signals that the nervous system can interpret. Different types of sensory receptors are responsible for different senses, including photoreceptors for vision, mechanoreceptors for touch, and chemoreceptors for taste and smell. These receptors are located throughout the body, including the skin, eyes, ears, and nose. They play a crucial role in helping organisms perceive their surroundings and react appropriately. By sending information to the brain, sensory receptors enable us to experience the world around us.
