The false pelvis is located in the upper part of the pelvic bone, specifically within the ilium.
Understanding the False Pelvis (Greater Pelvis)
The false pelvis, also known as the greater pelvis or pelvis major, is the region of the pelvis situated above the pelvic brim (also known as the linea terminalis). It is essentially the space enclosed by the flared portions of the iliac bones.
Key Features and Location Details:
- Ilium: The ilium, the uppermost and largest bone of the pelvis, contributes significantly to the formation of the false pelvis. Its expanded superior portion creates a wing-like structure.
- Above the Pelvic Brim: The false pelvis is defined as the area superior to the pelvic brim, an imaginary line that runs from the sacral promontory to the pubic symphysis. This line demarcates the boundary between the false and true pelvis.
- Support for Abdominal Structures: The false pelvis provides support for the lower abdominal organs and also serves as an attachment point for various abdominal muscles.
Function of the False Pelvis
While not directly involved in childbirth, the false pelvis plays a crucial role in:
- Supporting the abdominal contents.
- Providing attachment points for abdominal muscles.
- Guiding the developing fetus into the true pelvis during late pregnancy.
In summary, the false pelvis is located in the upper section of the pelvic bone, formed mainly by the ilium, and is situated above the pelvic brim.
