\_\_\_\_\_\_\_\_\_\_\_\_ line the gastric pit and secrete mucous and bicarbonate ions to protect the epithelium from digestion by gastric juice (contains HCl and pepsin) present in the stomach lumen
**Surface mucous cells**
47
\_\_\_\_\_\_\_\_\_\_\_\_ are found dispersed between the parietal cells; secret mucus (thinner than the secreted by surface mucous cells)
**Neck mucous cells**
48
\_\_\_\_\_\_\_\_\_\_\_\_ are round cells that contain distinct eosinophilic cytoplasm and round, prominent nucleus; secrete HCl and intrinsic factor, needed for absorption of vitamin B12
**Parietal (oxyntic) cells**
49
Identify the cells indicated by the arrows in this H&E section of the canine stomach
Parietal (oxyntic) cells
50
\_\_\_\_\_\_\_\_\_\_\_\_ are found near the base of the gastric glands; basophilic contain basally positioned nucleus and prominent basophilic apical cytoplasm filled with many ribosomes; secrete pepsinogen (converted to pepsin in the acidic environment of the stomach)
