Question

Give 3 differences in the pelvic structure of males and females:

Answer 1

The pelvic structure of males and females differ in bone thickness and weight, pelvic shape and size, and shape of the sacrum and pelvic cavity.

Step-by-step explanation:

The pelvic structure of males and females differ in several ways:

1. Bone thickness and weight: The bones of the male pelvis are thicker and heavier compared to females, as they are adapted to support the male's stronger muscles and heavier physical build.
2. Pelvic shape and size: The female pelvis is wider than the male pelvis to accommodate childbirth. The greater sciatic notch of the male hip bone is narrower and deeper than that of females. The subpubic angle, which is the angle between the pubic bones, is larger in females (greater than 80 degrees) compared to males (less than 70 degrees).
3. Shape of the sacrum and pelvic cavity: The female sacrum is wider, shorter, and less curved compared to males. The lesser pelvic cavity of females is wider and more shallow compared to males, which have a narrower, deeper, and tapering lesser pelvis.
