Uterotubal junction

Uterotubal Junction

The Uterotubal junction is an important anatomical structure in the female reproductive system. It is the point where the uterus and the fallopian tube meet. This junction plays a crucial role in the transport of sperm, ovum, and the embryo.

Anatomy

The uterotubal junction is located at the superior corner of the uterine cavity, where the uterus and fallopian tube intersect. The junction is lined with ciliated epithelium, which aids in the movement of the ovum from the fallopian tube to the uterus.

Function

The primary function of the uterotubal junction is to facilitate the transport of the ovum from the ovary to the uterus. It also acts as a barrier to prevent the backflow of menstrual blood into the fallopian tubes, and to prevent the ascent of bacteria from the vagina into the upper reproductive tract.

Clinical Significance

The uterotubal junction is a common site for the implantation of an ectopic pregnancy. This can occur if the junction becomes blocked or damaged, preventing the fertilized egg from reaching the uterus.
