Open in App
Solution
The correct option is D Mechanoreceptor
A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. Normally, there are four main types in glabrous skin: Pacinian corpuscles, Meissner's corpuscles, Merkel's discs and Ruffini endings. There are also mechanoreceptors in hairy skin and the hair cells in the cochlea are the most sensitive mechanoreceptors, transducing air pressure waves into nerve signals sent to the brain. In the periodontal ligament, there are some mechanoreceptors, which allow the jaw to relax when biting down on hard objects, the mesencephalic nucleus is responsible for this reflex.
