The inner surface of the fallopian tubes is lined by a specialized epithelium. Which of the following cell junctions is primarily responsible for preventing the leakage of body fluids across this tissue layer?
Options
- AAdhering junctions
- BGap junctions
- CIntercalated discs
- DTight junctions
Correct answer
D. Tight junctions
Step-by-step solution
The inner surface of the fallopian tubes is lined by ciliated epithelium. In epithelial tissues, specialized junctions provide structural and functional links between individual cells. Tight junctions help to stop substances from leaking across a tissue, fulfilling the physiological requirement of preventing fluid leakage. Adhering junctions perform cementing to keep neighbouring cells together, and gap junctions facilitate communication between cells by connecting their cytoplasm. Intercalated discs are specialize
