उत्तर
Fallopian tubes:
These are a pair of muscular ducts lying horizontally over the peritoneal cavity. The proximal part of the tube lies close to the ovary and distally it opens into the uterus. Each tube is 10 to 12 cm in length. It is internally lined by ciliated epithelium.
It can be divided into three regions:
- Infundibulum:
The proximal funnel-like part with an opening called ostium surrounded by many finger-like processes called fimbriae (of these at least one is long and connected to the ovary). The cilia and the movement of fimbriae help in transporting the ovulated egg to the ostium. - Ampulla:
It is the middle, long and straight part of the oviduct. Fertilization of the ovum takes place in this region. - Isthmus/Cornua:
The distal narrow part of the duct opening into the uterus. - Functions:
- Fallopian tubes carry the released egg from the ovary to the uterus.
- Ampulla provides the site for fertilization of the ovum.
