Innervation of the ventral diaphragm of the locust (Locusta migratoria).
1. Innervation and some electrical properties of the locust ventral diaphragm were investigated with electrophysiological and histological methods. 2. Muscle fibres are coupled electrically. Electrical stimulation evokes a graded active membrane response. 3. Each segment is innervated by four motor neurones as follows. Two motor neurones are situated in each abdominal ganglion. Branches of thei...
متن کاملPhotoinactivation of an identified motoneurone in the locust Locusta migratoria.
1. The common inhibitory motoneurone 1 (CI1) in the mesothoracic ganglion of the locust was photoinactivated using a helium-cadmium laser or a mercury lamp as light source. Treated animals showed no signs of abnormal locomotory behaviour over periods of up to 40 days. 2. Photoinactivation of part of the neurone in the ganglion, i.e. the soma and the primary neurite, is sufficient to cause irrev...
متن کاملMaximum metabolic rate, relative lift, wingbeat frequency and stroke amplitude during tethered flight in the adult locust Locusta migratoria.
Flying insects achieve the highest mass-specific aerobic metabolic rates of all animals. However, few studies attempt to maximise the metabolic cost of flight and so many estimates could be sub-maximal, especially where insects have been tethered. To address this issue, oxygen consumption was measured during tethered flight in adult locusts Locusta migratoria, some of which had a weight attache...
متن کاملThe uptake and release of serotonin and dopamine associated with locust (Locusta migratoria) salivary glands
The uptake and release characteristics of dopamine and serotonin in the salivary glands of the locust Locusta migratoria were examined. Cyclic AMP levels were determined in salivary glands in which the salivary nerve was stimulated under different experimental paradigms. Stimulation of the salivary nerve leads to time- and frequency-dependent elevations of cyclic AMP levels in the glands. The p...
متن کاملAn electron - microscope study of the cytoplasmic inclusions in the neurones of Locusta migratoria
The cytoplasmic inclusions of the neurones of adult Locusta migratoria have been examined in the electron microscope. The mitochondria are easily recognized by their cristae and outer double membranes. Electron-dense inclusions, also with an outer double membrane but possessing numerous closely spaced internal lamellae in various orientations, are probably small lipochondria. Larger and more di...
