Final answer:
The obturator foramen is not smaller in the female pelvis; in fact, the female pelvis is broader with wider anatomical features to facilitate childbirth.
Step-by-step explanation:
The statement that the obturator foramen is small in the female pelvis is false. The female pelvis, adapted for childbirth, is broader with certain anatomical features that are different from the male pelvis. It has a larger subpubic angle, a rounder pelvic brim, and a wider and more shallow lesser pelvic cavity than the male pelvis. The sciatic notch is also broader, reflecting the overall adaptability of the female pelvis for reproductive functions. These distinctions, such as the width of the greater sciatic notch and the angle of the pelvic inlet, provide a broader pelvic outlet in females, aiding in childbirth.
