Sulla fine struttura delle cellule gustative delle papille circumvallate, foliate e fungiformi di pipistrelli ibernanti
The cells of vallate, foliate and fungiform papillae were studied in insectivore hibernating bats (Pipistrellus pipistrellus and Rhinolophus ferrumequinum) in the various epochs of the year in order to show cell types the seasonal changes. On the basis of the ultrastructural aspects and the relation...
