Sensory cells are specialized cells in the body that detect and respond to various stimuli from the environment. They play a crucial role in our senses, such as sight, hearing, taste, smell, and touch. These cells convert external signals into electrical impulses that can be interpreted by the nervous system, allowing us to perceive and interact with the world around us. Different types of sensory cells are found in specific organs. For example, photoreceptors in the eyes detect light, while hair cells in the inner ear respond to sound vibrations. Each type of sensory cell is adapted to its function, ensuring that we can experience a wide range of sensations.
