What Aids in the Movement of an Egg Cell Down

Question

What aids in the movement of an egg cell down a uterine tube?
A) Ciliary action only
B) Peristaltic contractions only
C) Both ciliary action and peristaltic contractions
D) Flagellum on the egg cell
E) Sperm

Accepted Answer

The movement of an egg cell down a uterine tube is facilitated by both ciliary action and peristaltic contractions. Cilia lining the uterine tube help to gently move the egg along, while peristaltic contractions of the tube's muscular walls aid in propelling the egg towards the uterus.
