Find reliable reference information to help answer these QUESTIONS about ciliary motion:

As shown below, c
iliary motion is a moving wave.  With the passage of one wave, each cilium goes through a power stroke phase, shown in green, and a recovery stroke phase, shown in red.

1). In what direction does the ciliary wave appear to be moving? (left-to-right, or right-to-left?)
2)  Note that the cilia are attached to a black bar..  In which direction would ciliary motion tend to propel this bar, if the bar was free to move?
3) What is meant by the term "metachronal rhythm"?
