Parietal cells

Mucous neck cells

Goblet cells.

Each of the following statements concerning the parietal cells of the gastric glands is true, EXCEPT

Secrete hydrochloric acid

Secrete pepsinogen

Their activity is stimulated by gastrin, histamine, and acetylcholine

Secrete an intrinsic factor

Each of the following statements concerning the pyloric region of the stomach is true, EXCEPT:

Pyloric gastric pits are deep and occupy about half of the mucosa thickness

Pyloric glands are tubular branched

Pyloric glands contain parietal cells

Each of the following statements concerning the undifferentiated cells of the gastric glands is true, EXCEPT

Are located mainly in the neck region of the glands

Are absent in the pyloric glands

Give rise to all glandular cell types

Serve for renewal of gastric surface epithelium

Each of the following statements concerning the intestinal villus is true, EXCEPT

Contains fenestrated sinusoidal blood capillaries

Contains a blind-ending lymphatic capillary called the lacteal

Lacks the covering epithelium

Each of the following statements concerning the enterocytes of the small intestine epithelium is true, EXCEPT

Are tall columnar

Lack microvilli

Are specialized for absorption and transport of substances from the gut lumen to circulation

Enterocyte junctions establish a barrier between the lumen and the intercellular compartment

Each of the following statements concerning the lipid absorption in the small intestine is true, EXCEPT

Enterocytes absorb fatty acids and glycerol from the lumen

Enterocytes resynthesize neutral fat

Neutral fat is transported into the lacteal

Neutral fat is transported into the blood capillaries

Each of the following statements concerning the Paneth cells of the small intestine mucosa is true, EXCEPT

Are located in villus epithelium

Have large acidophilic apical granules

Their granules contain the antibacterial enzyme lysozyme

Their lysozyme digests cell walls of certain bacteria

All mature cells arise from the common stem (intermediate) cells

Intermediate cells are located in the lower half of crypts

Epithelial cells, except Paneth cells, migrate from crypts onto villi

Paneth cells are stem cells for intestinal epithelium
