5. Fundic Glands: * Occupy most of mucosal thickness. * Perpendicular to the surface, reaching to muscularis mucosa (MM). MM *Very Crowded Minimal C.T. .
6. * Simple Branched Tubular Glands. * Open into lumen by short narrow ducts (Gastric Pits) * Pit: Secretory Portion : 1:3
8. Surface Mucous Cells: * Simple Columnar cells with basal oval Nuclei. * Line the surface epithelium and extend to line the pits . Function: Secrete “Neutral Mucus” which forms a “thick Blanket” for lubrication & protection.
10. Mucous Neck Cells * Located at the neck of the glands. * Low Columnar Cells with Vacuolated foamy cytoplasm. * Function: Secrete “Acidic Mucus” which protect gastric mucosa.
