Summary
The nerve endings in the epidermis of the hairless skin of the nose of the cat have been studied by means of light and electron microscopy. In the stratum germinativum there are Merkel's corpuscles. They consist of specialized cells with a thickened nerve fibre adjacent to each one of them. These receptors have been observed in two forms. Single cell-neurit-complexes are lying in the basal layer of the epidermis above the connective tissue papillae, and groups of these complexes are situated in the interpapillary pegs of the epidermis. The specialized cells are connected by desmosomes with the neighbouring cells of the epidermis. There are no free nerve endings in the hairless skin of the nose.
Zusammenfassung
Die Nervenendigungen in der Epidermis der haarlosen Haut der Katzennase wurden licht- und elektronenmikroskopisch untersucht. Im Stratum germinativum werden Merkeische Endigungen gefunden. Sie bestehen aus spezialisierten Zellen und je einer anliegenden verdickten Nervenfaser. Diese Rezeptoren werden in zwei Formen beobachtet. Einzelne Zell-Neurit-Komplexe liegen in der Basalschicht der Epidermis über den bindegewebigen Papillen und Gruppen solcher Komplexe im Stratum germinativum der Epidermalleisten (Epithelialzapfen). Die spezialisierten Zellen sind mit den umliegenden Epidermiszellen durch Desmosomen verbunden.
Freie Nervenendigungen konnten in der Epidermis der haarlosen Nasenhaut nicht beobachtet werden.
