Answer to Question 1

ANS: B
The levator ani is a collection of three pairs of muscles that support internal pelvic structures and resist increases in intraabdominal pressure. The fallopian tube divisions are the interstitial portion, isthmus, ampulla, and infundibulum. The linea terminalis is the imaginary line that divides the false from the true pelvis. The basin-shaped structure at the lower end of the spine is the bony pelvis.

Answer to Question 2

ANS: B
June 16 would be 18 days into the cycle; ovulation should have occurred at this point. June 10 would just be 8 days into the cycle and too early for ovulation. Ovulation occurs about 12 to 14 days after the beginning of the next menstrual period in a 28-day cycle; ovulation normally occurs about 14 days before the beginning of the next period. June 29 is at the end of the cycle. July 5 would be 27 days into the cycle and about time for the next period.
