Answer to Question 2

1
Rationale:
1. Estrogen-induced tubal peristalsis helps move the ovum through the tube, as the ovum has no inherent power of movement.
2. Progesterone-induced cervical changes can aid in ovum transport, but are not the primary mover.
3. Motions of the fallopian fimbriae occur as the ovum is released at ovulation, but do not facilitate the movement through the fallopian tube.
4. Movements of the corona radiata of the ovum surround the zona pellucida, and since the ovum has no inherent power of movement, do not facilitate movement through the fallopian tube.
