Despite apparent and wide morphological differences, cutaneous sensory endings, whether in the platypus, mole, opossum, pig, or man, are constructed along a basically similar pattern. The intricate nerve complexes of Eimer's corpuscles in the nose of moles and opossums are not appreciably different from the sensory nerve endings around human hair follicles. Mucocutaneous end organs are modifications of the superficial nerve network or of hair follicle end organs. We are in complete agreement with Winkelmann that many of the different cutaneous nerve endings described in the literature are largely artifacts. Skin must withstand compression and stretch; to avoid damage, its nerves must have enough available slack. Therefore, under normal conditions, they are so convoluted that tissue sections give the appearance of the different receptors.
