Question

5. It is a pelvis that has a kidney shaped brim in which the
anteroposterior diameter is reduced and the transverse diameter increased.​

Answer :

The pelvic inlet, or the upper pelvic narrow, is the anatomical limit between the true pelvis below and the false pelvis above. There are tangible, genetic and hormonal differences between the male and female pelvis related to the reproductive function.
