FIGURE 14.14 | Stomach: Basal Region of Gastric

(Fundic) Mucosa

The gastric glands (1, 9) in the body and fundus of the stomach show basal
branching (9). In the upper regions of the gastric glands, the chief or zymogenic

cells (6, 10) border the lumen of gastric glands (1, 9). In the basal regions, the
parietal cells (2) are wedged against the basement membrane and are not always
in direct contact with the lumen.

The lamina propria (3, 7) surrounds the gastric glands (1). A small
lymphatic nodule (4) is located in the lamina propria (3) adjacent to the gastric

glands (1, 9). The two layers of the muscularis mucosae (5), the inner circular
layer and the outer longitudinal layer, are seen below the gastric glands (1, 9).
Strands of smooth muscle (8) extend upward from the muscularis mucosae (5)

into the lamina propria (3, 7) between the gastric glands (1, 9).

Adjacent to the muscularis mucosae (5) is the submucosa (11).

FUNCTIONAL CORRELATIONS 14.3 ■ Stomach

The stomach receives, stores, mixes, digests, and absorbs some of the

ingested products. In addition, the stomach cells secrete different hormones
that regulate digestive functions. Some functions are designed specifically to
reduce the mass of ingested food material, or bolus, to a semiliquid mass
