| the jumping mechanism of cicada cercopis vulnerata (auchenorrhyncha, cercopidae): skeleton-muscle organisation, frictional surfaces, and inverse-kinematic model of leg movements. | in auchenorrhyncha, jumping is achieved by metathoracic muscles which are inserted into the trochanter of the hind leg. the synchronisation of movements of the hind legs is a difficult problem, as the leg extension that produces the jump occurs in less than 1 ms. even slight asynchrony could potentially result in failure of a jump. both the synchronisation of the movements of a pair of jumping legs, and their stabilisation during a jump, seem to be important problems for small jumping insects. t ... | 2004 | 18089035 |
