HHZ_007_Tastsinn / mechanoreceptor

Die taktile Wahrnehmung wird durch Mechanorezeptoren in der Haut, die so genannten Merkel-Zellen, Ruffini-, Meissner- und Vater-Pacini-Körperchen ermöglicht. A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. There are four main types in the glabrous skin of humans: Pacinian corpuscles, Meissner's corpuscles, Merkel's discs, and Ruffini corpuscles. When a mechanoreceptor receives a stimulus it begins to fire impulses or action potentials at an elevated frequency (the stronger the stimulus the higher the frequency).
