part_of adult salivary gland type III acini adult salivary gland F cell Cell found in the type III acini of the salivary gland. These cells deplete their granules within two days after attachment. Thereafter, they transform, develop an elaborate basal labyrinth and a huge intra-acinar lumen. They complete their transformation and their fullest development during the period of rapid engorgement. They are now specialized for rapid water and electrolyte secretion which enables the tick to suck huge quantities of blood while eliminating the excess blood meal water.
