Inspired by how human skin sense the stress field with layered structure and distributed … A mechanoreceptor, also called mechanoceptor, is a sensory receptor that responds to mechanical pressure or distortion. Mechanoreceptors are innervated by sensory neurons that convert mechanical pressure into electrical signals that, in animals, are sent to the central nervous system. Visa mer Cutaneous mechanoreceptors Cutaneous mechanoreceptors respond to mechanical stimuli that result from physical interaction, including pressure and vibration. They are located in the skin, like other Visa mer Mechanoreceptors are also present in plant cells where they play an important role in normal growth, development and the sensing of their environment. Mechanoreceptors aid the Venus flytrap (Dionaea muscipula Ellis) in capturing large prey.
