1. Brush border
The collection of microvilli forming a border on the intestinal side of the epithelial cells of the small intestine .

2. Carcinoembryonic antigen (CEA)
This is an antigen in blood which is elevated in certain cancers of epithelial origin, notably colon, breast, lung and stomach. CEA is a molecule expressed on surfaces of epithelial cells during embryogenesis but is later confined to only the apical surface. Its function is related to cell adhesions. Tumor formation is accompanied with elevated expression of CEA. Blood CEA levels is a tumor marker to detect the recurrence of cancer or residual activity of cancer after surgery. However, CEA is a non-specific marker of cancer, and may be elevated in noncancerous conditions such as cigarette smoking, ulcerative colitis, liver disease, and lung infection. Therefore, CEA is not useful as a screening test. (Normal levels of serum carcinoembryonic antigen are 0 to 2.5 ug/L.)

3. Gonorrhea
A sexually transmitted disease that is caused by a bacterium that inflames and damages epithelial cells of the reproductive system .

4. Mesentary
Epithelial cells supporting the digestive organs.

5. Micelles
Structures formed when bile salts surround digested fats in order to enable the water-insoluble fats to be absorbed by the epithelial cells lining the small intestine .

6. Prostate specific antigen (PSA)
This is a glycoprotein found in the cytoplasm of epithelial cells of prostate (a gland in the base of the penis). Its level in the blood may be elevated in men who have a benign or a malignant growth in the prostate. For this reason, the PSA test does not always distinguish between benign prostate conditions (which are very common in older men) and cancer. However, its level is useful as a screening test for early detection and to monitor the effectiveness of prostate cancer treatment over time. (Normal range: less than 4 ng/mL)
