Processes of secretion, restitution, and resorption in gland of mid-gut of Atya spinipes Newport


, : Processes of secretion, restitution, and resorption in gland of mid-gut of Atya spinipes Newport. Physiol Zool 28(1): 40-54

Secretion by and resituation in the gland of the mid-gut are rhythmical processes. Granule formation and the so-called "ripening processes" are closely connected with the Golgi substance, which disappears during "ripening". Other cell structures do not seem to be morphologically correlated with these processes. The role of the plastosomes, found in the embryonic cells, remains unknown. There appears to occur a strong resorption of digested material by this gland, particularly by the so-called "light" cells. Resynthesis of fat also occurs here.
