Which characteristic best describes the levator ani?

  • A. Division of the fallopian tube
  • B. Collection of three pairs of muscles
  • C. Imaginary line that divides the true pelvis and false pelvis
  • D. Basin-shaped structure at the lower end of the spine
Correct Answer: B

Rationale: The correct answer is B: Collection of three pairs of muscles. The levator ani is a group of muscles in the pelvis that includes the puborectalis, pubococcygeus, and iliococcygeus muscles. These muscles provide support to the pelvic organs and play a role in bowel and bladder control. The other choices are incorrect because the levator ani is not related to the fallopian tube (A), an imaginary line dividing the true and false pelvis (C), or a basin-shaped structure at the lower end of the spine (D).
