## Summary

The uterine tubes are a pair of smooth muscle lined tubes which blend the uterus medially and open to the peritoneal cavity immediately adjacent to the ovaries laterally.

## Anatomy

The fallopian tubes can be divided into sections:

1. **Infundibulum**: The wide, funnel-shaped end of the fallopian tube closest to the ovary. The infundibulum is associated with **Fimbrae**, finger-like projections close to the ovary which are designed to catch an egg released from the ovary at time of ovulation, and sweep it into the fallopian tube via ciliary action.
2. **Ampulla**: The middle part of the fallopian tube, which connects the infundibulum to the isthmus. The ampulla is the most common site of ectopic pregnancy
3. **Isthmus**: The narrow part of the fallopian tube that connects the ampulla to the uterine part

## Blood supply and innervation

The uterine tubes are supplied predominantly by the ovarian and uterine arteries, and are innervated by the ovarian and uterine plexuses.

## Function

The uterine (fallopian) tubes are essential for a number of reasons in females. They function to provide safe passage of an egg released during ovulation to the uterine cavity. The fallopian tube is the usual site of fertilisation.

## Clinical points

The uterine tubes are the most common site of ectopic pregnancy. The risk of this is increased if there has been previous scarring to the tube, for example from previous infection.
