1. Which of the following accurately compares the male and female pelvis? a. The female has a pubic arch angle of less than 90 degrees, whereas the male has a pubic arch angle of more than 90 degrees. b. The female pelvic brim is larger and wider than the male pelvic brim. c. The female pelvis is deeper than the male pelvis. d. The female pelvis has a smaller pelvic brim and a narrower pelvic outlet than that of the male pelvis.

The correct statement comparing the male and female pelvis is: b. The female pelvic brim is larger and wider than the male pelvic brim. This adaptation allows for childbirth, as a wider pelvic inlet provides more space for the baby's passage during delivery. While comparing pelvises, it’s key to remember that the female pelvis is generally broader and has a more circular inlet compared to the male pelvis, which is more heart-shaped and narrower. This anatomical difference is not just about childbirth; it also influences gait and balance, allowing women to have a more stable posture when they walk.
