Function of cilia in uterine tube?

The primary function of cilia in the fallopian tubes (uterine tubes) is to facilitate the transport of the egg from the ovary to the uterus during fertilization. Multiple layers of cells line the fallopian tubes, and the innermost layer, known as the ciliated epithelium, contains specialized cells called ciliated cells. These cells have hair-like projections called cilia that extend into the lumen of the fallopian tubes. The synchronized beating of these cilia creates a wave-like motion that propels the egg toward the uterus.

Here is a more detailed explanation of the function of cilia in the fallopian tubes:

1. Ciliary Action: The cilia in the fallopian tubes are constantly moving, creating a fluid-filled environment that encourages egg movement. As they beat in a coordinated manner, they generate a current known as the ciliary current.

2. Trapping and Transport: When the ovary releases an egg during ovulation, the fimbriae, finger-like projections at the end of the fallopian tube, help capture it. The cilia then transport the egg toward the uterus by sweeping it along the inner lining of the fallopian tube.

3. Protecting the Egg: The cilia help protect the egg during its journey through the fallopian tubes. By maintaining fluid movement, they prevent the egg from adhering to the walls of the tube and aid in preventing complications like ectopic pregnancy.

4. Supporting Fertilization: The ciliary currents also contribute to the mixing of sperm and egg within the fallopian tubes, thereby enhancing the chances of fertilization occurring.

Overall, the cilia in the fallopian tubes play a crucial role in the process of fertilization by ensuring that the egg is transported efficiently from the ovary to the uterus, maximizing the likelihood of successful conception and pregnancy.
