Transverse section of the filter plates (lamella) of a mandibular ramus of a Muscovy Duck (Cairina moschata) (HE): distribution of Herbst Corpuscles
Herbst corpuscles are the most widely distributed mechanoreceptors in birds. They are present in the deep dermis all over the body, occur adjacent to joint capsules and feather follicles and are present in muscles and tendons. They are especially numerous in the beak and oral cavity.
Herbst corpuscles are pressure receptors. They resemble the Pacinian corpuscles of mammals and detect rapid mechanical deformation ( vibration).
