Differences between male and female pelvis

Question 1

Sex-based differences between males and females are evident in the pelvis, due partly to the larger size and muscle mass of males and partly to adaptations in females for childbearing. Generally, the female pelvis has lighter bones with smoother surfaces; it is broader and shallower than the male pelvis. The broad surface of the __ , known as the ala or wing, projects farther laterally in females, but the superior iliac crest is comparatively closer to the level of the sacrum.

Answer 1

ilium (also known as ala)

Question 2

The ___ formed between the 2 pubis bones at the pubic symphysis is larger in females.

Answer 2

subpubic angle

Question 3

The sacrum and coccyx are less curved in females at the inferior, anterior side, leading to a larger and more circular opening at the inferior side of the cavity known as the ___. Overall, the true pelvis is wider and more oval in females to allow for childbirth, while it is narrower and somewhat heart-shaped in males.

Answer 3

true pelvis
