Final answer:
The Ovarian hilum is the part of the ovaries that is continuous with the mesoovarium, serving as the point of attachment and the path for blood vessels and nerves.
Step-by-step explanation:
The part of the ovaries that is continuous with the mesoovarium is the Ovarian hilum. The ovaries are supported by the mesovarium, which is an extension of the peritoneum that connects the ovaries to the broad ligament. The mesovarium is responsible for attaching the ovaries within the pelvic cavity and plays a crucial role in the positional stability of the ovaries. Specifically, the ovarian hilum is where the mesovarium attaches to the ovary and is the entry and exit point for blood vessels, nerves, and lymphatics that serve the ovary.
