OSCILLATORY CONTRACTION OF INSECT FLIGHT MUSCLE.
Abstract
Studies on glycerine-extracted fibres have shown that the oscillatory contractile properties of insect fibrillar flight muscle derive from certain peculiarities of the myofibrils, particularly an increase in ATPase activity when the fibres are extended and a stimulating effect of low concentrations of ADP. The molecular architecture differs in certain respects from that of vertebrate striated muscle. Giant water bugs, which provide the best source of fibrillar flight muscle, can be maintained in good condition in the laboratory. Certain species have been bred successfully but full maturation of the flight muscles has not yet been achieved. (Author)
