Question

Quizplus · Accepted Answer

The movement of an egg down the oviduct is due to tubular muscle contractions and the action of cilia within the oviduct. The muscles contract to move the egg along, while the cilia help to propel the egg and move mucus along the oviduct. Whip-like flagellar action is not involved in the movement of the egg, and suction from the uterine contractions is not a significant factor in the movement of the egg.
