How do animals move quickly: Interactions between brain, muscle and skeleton
-

University of Cambridge, Zoology, United Kingdom
Jumping is one of the fastest and most demanding movements that animals produce. Such movements place huge constraints on the underlying neural control mechanisms, the interactions between muscles and joints, and on the ability of the skeleton to store energy. The solutions to these basic problems are being studied in insects, some of which can accelerate to take-off velocities of 5 m s-1 in less than 1 ms, thus experiencing forces in excess of 500 g. Catapult mechanisms are frequently used in which force production is separated from directional control in both elevation and azimuth. The various specialisation needed are revealed by a combination of electrophysiology, high speed imaging, UV microscopy, and mechanical analyses and modelling.
