A survey covering the serous (granular) cutaneous glands in several anuran families from the Old and New Worlds (Bombinatoridae, Discoglossidae, Ranidae, Hylidae, Pseudidae and Leptodactylidae) has revealed consistent patterns of complex interactions between the syncytial secretory unit and serous deposits (granules). These relationships involve outgrowths from the syncytial cytoplasm encircling the granules and complex invaginations of the perigranular compartment (halo) into the syncytium. The outgrowths are branched, cytoplasm processes resembling ramified microvilli, or can be larger, dome-like to cylindrical structures. Despite their different features and origins, all these structures are efficient devices for amplifying the cytoplasmic surfaces round the granules, so improving exchange between the secretory syncytium and serous product. These complex secretory granule-cytoplasm interactions affect the product released from the Golgi apparatus and are consistent with the hypothesis of prolonged serous maturation following the initial phase of biosynthesis. Post-Golgian maturation modifies the secretory material on a centripetal gradient, causing condensation and, possibly, the transfer of component molecules from and/or to the cytoplasm.
