The outlet of the pelvis refers to the lower opening or passage of the pelvis, specifically the bony structure that forms the lower boundary of the pelvic cavity. It serves as the exit point for various structures and organs located within the pelvis.
Anatomically, the outlet of the pelvis is comprised of several bony structures, including the sacrum, coccyx, and the two ischial tuberosities (the bony prominences commonly known as the sit bones). It is also referred to as the pelvic floor, pelvic diaphragm, or infrapelvic aperture.
The outlet of the pelvis is vital in facilitating childbirth, as the baby must pass through this opening during delivery. The dimensions of the outlet play a crucial role in determining whether a vaginal birth is possible, as it needs to be adequate in size to allow the baby's head to pass through comfortably.
The pelvic outlet is also important for other functions beyond childbirth. It enables the passage of the rectum and anus, allowing for the elimination of waste. Additionally, it provides a path for the urethra in both males and females, allowing for the release of urine.
In summary, the outlet of the pelvis refers to the lower opening or passage of the pelvic cavity. It consists of the bony structures that form the base of the pelvis and serves as the exit point for various structures and organs, including the baby during childbirth, the rectum, and the urethra.
