Query: Mechanical oscillations at the cellular scale   Active phenomena which involve force generation and motion play a key role in
a number of phenomena in living cells such as cell motility, muscle contraction
and the active transport of material and organelles. Here we discuss mechanical
oscillations generated by active systems in cells. Examples are oscillatory
regimes in muscles, the periodic beating of axonemal cilia and flagella and
spontaneous oscillations of auditory hair cells which play a role in active
amplification of weak sounds in hearing. As a prototype system for oscillation
generation by proteins, we discuss a general mechanism by which many coupled
active elements such as motor molecules can generate oscillations.
