A The female bony pelvis is broader and flatter than the male pelvis.

B The pelvic inlet is narrower than the pelvic outlet.

C The iliac crest is an important landmark in measuring the progress of the fetus
down the birth canal.

D The sutures in the fetal skull are strong hard joints that hold the skull bones rigidly
in place.

E A newborn baby’s pulse can be seen beating in the anterior fontanel.

Answer

A is true. The female bony pelvis is broader and flatter than the male pelvis.

B is false. The pelvic inlet is wider (not narrower) than the pelvic outlet.

C is false. The iliac crest is the protuberance at the front of each hip bone; it is not
important in measuring the progress of the fetus down the birth canal.

D is false. The sutures in the fetal skull ‘give’ a little under the pressure in the birth
canal, allowing the skull bones to move to a small extent. This makes it easier for the
baby’s head to pass through the mother’s bony pelvis.

E is true. A newborn baby’s pulse can be seen beating in the anterior fontanel.

5. List four possible features of the maternal bony pelvis and/or the fetal skull that

Answer

The possible features of the maternal bony pelvis and/or the fetal skull that may result
in a difficult labor and delivery include (you only had to suggest four):
- A narrow or deformed pelvis
- Abnormal growth of tissue in the pelvic cavity
- A large fetal skull
- A brow, face, breech or shoulder presentation of the fetus
- A fetus that does not present the widest part of its skull to the widest part of the
pelvic inlet, and then rotate to do the same in the pelvic outlet.
