What is the Mesovarium?

A

Connects the Ovaries to the Broad Ligament.

93
Q

What is the Round Ligament?

A

Extends from the Uterus to the Labia Majora via the Inguinal Canal,
And acts to maintain the Uterusโ€™ Anteverted Position.

94
Q

Describe the Course of the Round Ligament?

A
  1. Originates at the Uterine Horns in the Fundus of the Uterus,
  2. Exits the Pelvis via the Deep Inguinal Ring,
