Endometrial cavity

Endometrial Cavity

The endometrial cavity is the central tissue-lined space within the uterus of female mammals, including humans. It is a vital component of the female reproductive system, playing a key role in the menstrual cycle and pregnancy.

Anatomy

The endometrial cavity is a thin, flat space, located between the two layers of the endometrium, the mucous membrane that lines the uterus. The cavity is triangular in shape in its cross-section and has a length of approximately 7 cm. It is connected to the cervical canal at its lower end and the fallopian tubes at its upper corners.

Function

The primary function of the endometrial cavity is to house and nourish a fertilized ovum or egg until it develops into a fetus. The endometrial lining of the cavity undergoes cyclical changes in response to hormonal fluctuations during the menstrual cycle. If fertilization does not occur, the lining is shed during menstruation.

Clinical Significance

Abnormalities in the endometrial cavity can lead to various health issues, including infertility, endometriosis, and endometrial cancer. Diagnostic procedures such as hysteroscopy and ultrasound are often used to examine the endometrial cavity and detect any abnormalities.
