[ « 5 o] THE ELECTRICAL AND MECHANICAL RESPONSES OF THE PROTHORACIC FLEXOR TIBIALIS MUSCLE OF THE STICK INSECT, CARAUSIUS MOROSUS BR.

Insect muscles are innervated by relatively few motor axons. Some or all of these axons may evoke different electrical and mechanical responses in the muscle fibres they innervate (see Hoyle, 1957 a). Only one full analysis of the neuromuscular mechanisms of an insect muscle has been made, on the jumping muscle of th
