The mesosalpinx is the fold of peritoneum that drapes over the uterine tubes.
Let's break that down:
- Peritoneum: This is the serous membrane lining the abdominal cavity and covering most of the abdominal organs. It provides support and allows for movement.
- Uterine Tubes (Fallopian Tubes): These tubes connect the ovaries to the uterus, providing a pathway for the egg to travel.
In essence, the mesosalpinx is a part of the broad ligament of the uterus, specifically the section that supports the fallopian tube. As indicated in the reference, it's a "fold of peritoneum draping over both uterine tubes" [4, 5]. It helps to suspend the uterine tubes and carries their blood vessels and nerves.
| Term | Description | Function |
|---|---|---|
| Mesosalpinx | Fold of peritoneum draping over the uterine tubes; part of the broad ligament. | Supports the uterine tubes, carries blood vessels and nerves to the tubes. |
| Mesovarium | Fold attaching the anterior ovary to the posterior broad ligament; does not cover the entire ovary. | Helps keep the ovary in position within the pelvis. |
| Broad Ligament | A wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis. | Supports the uterus, fallopian tubes, and ovaries. |
In comparison to the mesovarium, which attaches the ovary to the broad ligament, the mesosalpinx specifically supports the uterine tube. The mesovarium "does not cover the entire surface of each ovary but helps to keep its position within the pelvis" [4, 5].
