The crypts (i.e., mucosal glands) of the small intestine lie within a lamina propria which is rich in lymphocytes, eosinophils, and plasma cells.
Most of their epithelial cells are absorptive, and are tall columnar with purple cytoplasm. A few of their cells are goblet cells, i.e., mucus producers. They appear plump and stain pale, with the nucleus pushed to the bottom.
This is a group of small intestinal crypts.
