What is the primary function of the fimbriae of the uterine (fallopian) tube?
Solution
Correct Answer: Option A
- The primary function of the fimbriae of the uterine (fallopian) tube is to guide the ovum into the fallopian tube.
- After ovulation, the fimbriae, which are finger-like projections located at the distal end of the fallopian tube, actively sweep over the surface of the ovary.
- This movement helps to capture the released ovum and direct it into the lumen of the fallopian tube, where fertilization typically occurs.
- The fimbriae do not provide muscular contractions for ovum transport; instead, the muscular walls of the fallopian tube and ciliary action facilitate the movement of the ovum towards the uterus.
- Additionally, the fimbriae do not secrete nourishing fluids for the ovum, nor do they have a role in preventing the retrograde movement of sperm.
In summary, the fimbriae's critical role is to ensure the ovum enters the fallopian tube promptly after ovulation, enabling its potential meeting with sperm for fertilization.
