The document discusses the bones and diameters of the female pelvis. It notes that the female pelvis is usually roomier than the male pelvis, which can become flattened due to diseases like rickets. It provides the measurements of the pelvic brim, cavity, and outlet in females. It also identifies important pelvic bones and landmarks, including the sacrum, pubis, iliopectineal line, and sacral promontory. Finally, it references two textbooks on midwifery as sources.
