Fig 11. 93W6814, Gallbladder, human, H&E.
The mucosa consists of a tall simple columnar absorptive
epithelium resting on a lamina propria (L) of loose connective
tissue. Only one cell type, tall columnar cells, is present in the
epithelial layer. The nuclei are in the basal portion of the cell.
The cells possess a thin apical striated border. The lamina
propria underlying the epithelium is usually very cellular
containing lymphocytes, the blood vessel (BV) and lymphatic
vessels (LV).
