What does the pelvic cavity refer to?

The pelvic cavity usually refers to the hollow space formed by the hip bones, sacrum, coccyx, and other connected bones.

Generally located in the lower to middle abdomen of the human body, the pelvic cavity is composed of various interconnected bones. It is typically characterized by a short anterior wall and a longer posterior wall. This bony structure provides protection for pelvic organs and tissues, such as the uterus and bilateral adnexa, as well as the bladder anteriorly and the rectum posteriorly. Additionally, in females, the pelvic cavity tends to be slightly wider and shallower compared to males, which is generally more favorable for fetal delivery.

During pregnancy, hormonal changes in women can cause slight ligamentous laxity and minor loosening of joints, potentially leading to symphysis pubis diastasis, which often results in pelvic pain.
