Mechanoreceptors are specialized sensory cells that respond to mechanical stimuli, such as pressure, touch, vibration, and stretch. They are found in various parts of the body, including the skin, muscles, and internal organs. These receptors convert physical forces into electrical signals, allowing the nervous system to interpret sensations. There are different types of mechanoreceptors, each tuned to specific types of mechanical changes. For example, Merkel cells detect light touch, while Pacinian corpuscles respond to deep pressure and vibration. Together, these receptors play a crucial role in our ability to perceive and interact with our environment.
