Touch receptors are specialized nerve endings in the skin that detect various sensations, such as pressure, temperature, and pain. These receptors help the body respond to external stimuli, allowing us to feel and interact with our environment. There are different types of touch receptors, including Meissner's corpuscles for light touch and Pacinian corpuscles for deep pressure. When the skin is stimulated, touch receptors send signals to the brain through the nervous system. The brain then interprets these signals, enabling us to perceive sensations. This process is essential for everyday activities, such as holding objects or feeling textures.
