What separates the true and false pelvis?

An imaginary oblique line passing from the sacral promontory to the superior aspect of the symphysis pubis divides the pelvis into the false or greater pelvis superiorly and the true or lesser pelvis inferiorly.

Where is the true pelvis The false pelvis?

The false pelvis is superior and is surrounded by iliac fossa portions of the coxal bones and the upper portion of the sacrum. The true pelvis is inferior and is surrounded by the pubis and ischium portions of the coxal bones, in addition to the lower sections of the ilium and the sacrum.

What is the false pelvis?

Anatomical Parts The greater pelvis (false pelvis) is the expanded portion of the cavity situated above and in front of the pelvic brim.

What is included in the true pelvis?

The pelvic cavity (the true pelvis) predominantly contains the urinary bladder, the colon, and the internal reproductive organs. This space is enclosed between the pelvic inlet and the pelvic outlet.

Where does the true pelvis start?

The true pelvis is considered to start at the level of the plane passing through the promontory of the sacrum, the arcuate line on the ilium, the iliopectineal line and the posterior surface of the pubic crest.

What is the difference between the female and male pelvis?

The female pelvis is larger and broader than the male pelvis, which is taller (owing to a higher iliac crest), narrower, and more compact. The distance between the ischium bones is small in males. This results in the female inlet being large and oval in shape, while the male inlet is more heart shaped.

Which is the most common type of female pelvis?

The gynecoid pelvis is the most common pelvis shape in females and is favorable for a vaginal birth. Other pelvis types, such as the android and platypelloid shapes, may lead to a more difficult vaginal birth or the recommendation of a C-section.
