Question

Which pelvic ligament provides posterior support to the uterus?

Broad ligament
Suspensory ligament
Cardinal ligament
Uterosacral ligament

Answer 1

The uterosacral ligament provides posterior support to the uterus, connecting from the cervix to the sacrum and stabilizing its position within the pelvic cavity.

Step-by-step explanation:

The ligament that provides posterior support to the uterus is the uterosacral ligament. This ligament stabilizes the position of the uterus by connecting from the cervix to the sacrum of the pelvic wall, offering posterior reinforcement. Other ligaments such as the broad ligament and round ligament also contribute to the support and stability of the uterus but serve different roles in its anatomical positioning.

The broad ligament, for instance, extends laterally from both sides of the uterus and attaches to the pelvic wall, primarily providing support to the uterus, while the round ligament connects the uterus near the uterine tubes and extends to the labia majora.

Answer 2

The uterosacral ligament provides posterior support to the uterus, connecting the cervix to the sacrum.

Step-by-step explanation:

The ligament that provides posterior support to the uterus is the uterosacral ligament. This ligament extends from the posterior aspect of the cervix and inserts onto the sacrum, ensuring the uterine position is stable from the back. While the broad ligament serves as a primary support structure on either side of the uterus, and the round ligament extends from the uterus to the labia majora, it is the uterosacral ligament that specifically provides the needed posterior support.
