1. Dentists can also apply solutions to seal or block the tubules . 2. The three dimensional configuration of the dentinal tubules is genetically determined. 3. The mechanism of diuresis involves the proximal tubule of the kidney. 4. There are fewer T-tubules in comparison with skeletal muscle. 5. These combinations of flame cells and tubule cells are called protonephredia. 6. HEMA forms deep resinous tags and then occludes the dentinal tubules . 7. Testicular seminoma originates in the germinal epithelium of the seminiferous tubules . 8. Secretory tubules are lined with a single layer of epithelial cells. 9. Millions of sperm are produced daily in several hundred seminiferous tubules . 10. The smear layer prevented all the sealers from penetrating dentinal tubules .
