Mechanoreceptors are specialized sensory cells that respond to mechanical stimuli such as pressure, vibration, and touch. They are found in various parts of the body, including the skin, muscles, and internal organs. These receptors play a crucial role in our ability to perceive sensations like texture, sound, and body position. There are different types of mechanoreceptors, each tuned to specific types of mechanical changes. For example, Pacinian corpuscles detect deep pressure and vibration, while Meissner's corpuscles are sensitive to light touch. Together, these receptors help us interact with our environment and maintain balance and coordination.
