Summary

An electron microsopic study of the receptor organs and the innervation in the hard palate region of the beak of the hen is presented. Three morphologically different receptors were found: subepithelial Merkel cells, Herbst-corpuscles and free nerve endings.

The subepithelial Merkel cells with contacting axoplasmic plates are surrounded by lamellae originating from encapsulating cells of the Schwann cell type.

In the Herbst-corpuscle a description of the nerve terminal, based on serial sections, is given. The free nerve endings are mainly located in the outer region of the fibrous capsule of the Herbst-corpuscle.
