Morphological aspect of the skin terminal corpuscles, previous corrosion with pancreatin.
The capsulated corpuscles of the skin have been studied by pancreatin corrosion methods. With this corrosion, Meissner's corpuscles disappear while those, whose fundamental structure is collagenous, remain intact. We have observed structural differences in these collagenous corpuscles, some being formed as a fine reticulum or with longitudinal or concentric sheaths. Within the corpuscle, there is a totally vascular compartment, the 'vascular hill', which is easily differentiated from the other laminar or reticular segment which is the 'nerve hill'. We conclude that the connective tissue arrangement and the vascular content of the corpuscles contribute to the regulation of the different degrees of sensations perceived by these corpuscles. The tendency that these corpuscles show to unite may be caused because the places, where they are grouped, are the points of greatest sensory perception.
