part_of adult salivary gland type II acini adult salivary gland type III acini adult salivary gland type IV acini adult salivary gland acinar duct Fig. 8-10, in Biology of Ticks ISBN:0-19-505910-7. Narrow bifurcated duct that connects the acinus with the intralobular ducts. The acinar duct is surrounded by non-granular neckcells (=peritubular cells). At the center of the acinus is a small, narrow channel (lumen) communicating with the acinar duct. Evidently, the secretions from the granular cells pass initially into this narrow channel, then into the acinar duct for their passageout of the acinus into the intralobular duct and exit from the salivary glands.
