Infundibulum
The infundibulum is the part of the fallopian tube that is closest to the ovary. It is located at the end of the fallopian tube near the ovary and is responsible for capturing the released egg during ovulation. Here are some key points about the infundibulum:
- **Function**: The infundibulum has finger-like projections called fimbriae that help in capturing the egg released from the ovary during ovulation. The fimbriae create a sweeping motion to guide the egg into the fallopian tube.
- **Anatomy**: The infundibulum is funnel-shaped and has a wide opening to receive the egg. It is connected to the ampulla, which is the middle part of the fallopian tube.
- **Ovulation**: During ovulation, the egg is released from the ovary and enters the peritoneal cavity. The fimbriae of the infundibulum then sweep over the ovary to capture the egg and guide it into the fallopian tube.
- **Fertilization**: The infundibulum is the site where fertilization often occurs, as it is where the egg and sperm meet. After fertilization, the resulting embryo travels down the fallopian tube towards the uterus for implantation.
In conclusion, the infundibulum plays a crucial role in the reproductive system by capturing the egg, facilitating fertilization, and guiding the embryo towards the uterus.
