Adult Uterine Tube Histology
Uterine tube, Fallopian tube, oviduct, uterine horn.
Tube Anatomical Four Subdivisions
- Infundibulum is the funnel-shaped (up to 10 mm in diameter) end of the oviduct. Finger-like extensions of its margins, the fimbriae, are closely applied to the ovary. Ciliated cells are frequent. Their cilia beat in the direction of the ampulla of the oviduct.
- Ampulla - Mucosal folds, or plicae, and secondary folds which arise from the plicae divide the lumen of the ampulla into a very complex shape.. Fertilization usually takes place in the ampulla.
- Isthmus is the narrowest portion (2-3 mm in diameter) of the parts of the oviduct located in the peritoneal cavity. Mucosal folds are less complex and the muscularis is thick. An inner, longitudinal layer of muscle is present in the isthmus.
- Intramural part of the oviduct, which penetrates the wall of the uterus body. An inner, longitudinal layer of muscle is present.
