Final answer:
The parts of the uterine tubes include the infundibulum, ampulla, and isthmus. These tubes have three layers and contain ciliated cells that help move the ovulated oocyte.
Step-by-step explanation:
The uterine tubes, also known as fallopian tubes or oviducts, have several parts:
- The infundibulum, which is the wide distal end of each tube that has finger-like projections called fimbriae. The fimbriae help sweep eggs from the ovary into the tube.
- The ampulla, which is the middle region of the tube where fertilization often occurs.
- The isthmus, which is the narrow medial end of each tube that is connected to the uterus.
The uterine tubes also have three layers: an outer serosa, a middle smooth muscle layer, and an inner mucosal layer. The inner mucosa contains ciliated cells that beat in the direction of the uterus, helping to move the ovulated oocyte.
