The oviduct (also called Fallopian or uterine tube) transports ovum from the ovary to the uterus. Its wall is composed of three layers:
Mucosa - exhibits thin longitudinal folds that project into the lumen. These folds are a distinctive characteristic of the oviduct.
Simple Columnar Epithelium - consists of two types of cells:
Ciliated Cells - the cilia wave towards the uterus to help propel ovum or fertilized zygote to the uterus.
Peg Cells - secrete fluid that provides nutrients for the ovum or fertilized zygote.
Lamina Propria - connective tissue that supports the epithelium and contains blood vessels and nerves.
Muscularis - consists of an inner circular or spiral layer and an outer longitudinal layer whose peristaltic contractions help propel the ovum or fertilized zygote to the uterus.
Serosa - composed of a simple cuboidal epithelium (or mesothelium) supported by a thin layer of connective tissue.
Unlike many tubular tissues, there are no goblet cells or glands in the epithelium or any other glands in the wall of the oviducts.
