An 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...
متن کاملInvestigation of the histological development of the frontal ganglion in Locusta migratoria L. 1758 (Orthoptera, Acrididae)
Th e frontal ganglion plays a critical role in insect feeding and molting-related behaviors. It is present in all insect orders at all developmental stages. In this study, the histological development of the frontal ganglion of Locusta migratoria, the African migratory locust, was investigated. Ganglia were dissected at 3 distinct developmental stages and their histological structure was evalua...
متن کاملInnervation 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 کاملEvidence for the hormonal function of a CRF-related diuretic peptide (Locusta-DP) in Locusta migratoria
Locusta-DP is a corticotropin-releasing factor (CRF)-related diuretic peptide isolated from the migratory locust Locusta migratoria. At nanomolar concentrations, synthetic Locusta-DP stimulated fluid secretion and cyclic AMP production by Malpighian tubules isolated in vitro and increased the rate of amaranth clearance in starved locusts to levels comparable with those observed during post-feed...
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...
