Sensations are the physical feelings or perceptions that arise when our sensory organs detect stimuli from the environment. These stimuli can come from various sources, such as light, sound, touch, taste, and smell. Our body processes these signals through the nervous system, allowing us to experience the world around us. The five primary senses are sight, hearing, touch, taste, and smell. Each sense has specialized receptors that respond to specific types of stimuli. For example, photoreceptors in the eyes detect light, while taste buds on the tongue identify different flavors. Sensations play a crucial role in how we interact with our surroundings.
