Uterine Cavity

This specimen shows the uterine cavity and the cervical canal.

The uterus is divided into the fundus, the body and the cervix. In coronal section, the uterine cavity is triangular, broad above where the two uterine tubes join the uterus, and narrow below at the internal os of the cervix. The cervical canal is 2.5 cm long. The upper end communicates with the uterine cavity through the internal os and the lower end opens into the vagina at the external os. In nulliparous women, the external os is usually a circular aperture, whereas after childbirth it is a transverse slit.

Voiceover

In this specimen we can see the interior of the uterus and the cervix.

The uterus is divided into the fundus, the body and the cervix. The cavity of the uterine body usually measures 6 cm from the external os of the cervix to the wall of the fundus and is flat in its anteroposterior plane. In coronal section, it is triangular, broad above where the two uterine tubes join the uterus, and narrow below at the internal os of the cervix. The adult, non-pregnant cervix is narrower and more cylindrical than the body of the uterus and is typically 2.5 cm long. The upper end communicates with the uterine body via the internal os and the lower end opens into the vagina at the external os. In nulliparous women, the external os is usually a circular aperture, whereas after childbirth it is a transverse slit.
