FIGURE 13.21 | Serous Salivary Gland: Parotid

Gland

This photomicrograph illustrates a section of the parotid salivary gland. In
humans, the parotid gland is entirely composed of serous acini (1) and excretory
ducts. In this illustration, the serous acini (1) are filled with tiny secretory

granules. A small intercalated duct (2) with its cuboidal epithelium is
surrounded by the serous acini (1). Also on the right side is a larger, lighter-
stained excretory duct, the striated duct (3).

FIGURE 13.22 | Mixed Salivary Gland:

Sublingual Gland

The sublingual salivary gland exhibits both mucous acini (2) and serous acini
(3). The mucous acini (2) are larger and lighter staining than the serous acini (3),
and their cytoplasm is filled with mucus (1). The serous acini (3) are darker
staining with tiny secretory granules in the apical cytoplasm. The serous acini (3)

around the mucous acini (2) form crescent-shaped structures called serous
demilunes (4). A tiny excretory intercalated duct (5), lined with a cuboidal
