Answer to Question 1

ANS: A
The external female genitalia develop in the absence of androgens. The paramesonephric ducts are dominant in females, but this does not lead directly to the development of external genitalia. Ovaries are created when the medulla of the first primitive gonad regresses as the outer cortex becomes the ovary at around 10 weeks of gestation. Oogonia are underdeveloped fetal egg cells; it is not a process.

Answer to Question 2

ANS: D
The mons pubis is a layer of subcutaneous tissue anterior to the genitalia in front of the symphysis pubis. It is essentially a protective fat pad, and although it will not prevent fracture of the pelvis in a serious trauma, the mons pubis does offer some protection to these tissues. Blunt force is the usual cause of fractures. The pelvis is often fractured, especially in motor vehicle crashes. Some fractures do not show up immediately, but this is not the best answer because most do.
