At higher magnification
the serous secretory units characteristic of this salivary gland can be clearly
seen. The secretory cells, which form acini composed of a simple columnar
epithelium, have basophilic cytoplasm and rounded nuclei, located in the lower
half of the cell. Two intercalated ducts, lined by simple cuboidal epithelium
and with an investment of pink-staining collagenous connective tissue, can
also be seen. Note the flattened nuclei of capillary endothelial cells that
accompany the connective tissue throughout the gland.
