Video - Fallopian tube and uterus histology

The fallopian tubes are two thin tubes that extend from the uterus to the ovaries. They consist of 4 parts. First, there is the intramural part located in the myometrium of the uterus; the isthmus located lateral to the intramural part; the ampulla that follows and is the longest part; and the infundibulum situated at the distal end close to the ovaries.

The wall of each tube has three parts: the mucosa, the muscularis, and the serosa. The mucosa consists of a single layer of tall, columnar epithelium. In contrast, the muscularis has two layers: the inner circular layer and an outer longitudinal layer, the contraction of the muscularis creates peristaltic waves which move fertilized ovum forward. Finally, there is the serosa, which is the outermost layer.
