part_of adult body adult salivary gland Fig. 8-1, Fig. 8-2, Fig. 8-3, Fig. 8-4, in Biology of Ticks ISBN:0-19-505910-7. Paired glands comprised of clusters of white multicellular acini (lobes) arranged around a common salivary duct. The salivary glands are located in the antero-lateral regions of the body. The salivary glands are among the largest glands in the body. The salivary glands are comprised of two types of acini (alveoli), agranular acini (type I acaini) located near the anterior end of the gland and up to three types of granular acini (types II, III and IV), located in the middle and posterior regions of the gland. Agranular acini open directly into the main salivary duct. The granular acini open into intralobular ducts that ramify among the acini, eventually joining the main salivary duct.
