    Notizen: Summary The coxo-trochanteral muscle receptor organ of the hind leg of the locust Locusta migratoria migratorioides (R.&F.) has been investigated by use of scanning and transmission electron microscopy with special emphasis on its distal attachment site. The overall morphology of the receptor muscle, the sensory neuron and its dendrites was found to share many common features with other arthropod sense organs of that type with two important differences: (1) the connective tissue segment (= intercalated tendon) is extremely short compared to that of other muscle receptor organs; (2) the naked dendritic terminals of the non-ciliated, multipolar sensory neuron of the organ contain clusters of microtubules, interconnected by an amorphous matrix, that resemble the tubular bodies of ciliated, epithelial receptor cells.

    Segmental and interganglionic projections from primary fibres of insect mechanoreceptors (1978)
    Springer
    Cell & tissue research 194 (1978), S. 337-351

    ISSN: 1432-0878

    Notizen: Summary Projections of primary insect mechanoreceptor fibres in Locusta migratoria and Acheta domesticus are visualised with the cobalt intensification technique after axonal or dendritic filling with cobaltous chloride. Chordotonal proprioceptors of the locust mesothoracic thoracocoxal joint have typical segmental projections and more or less widespread interganglionic processes into the metathoracic, prothoracic and even suboesophageal ganglia. Similar observations can be made on locust abdominal chordotonal organs, from some of which all primary axons project into five preceding neuromeres or ganglia. From locust abdominal stretch receptors and cricket mechanosensitive sternal hairs single afferent axons extend through several ganglia. Locust campaniform sensilla and clavate hair projections of crickets terminate locally. It is concluded that many interganglionic primary afferents contribute to intersegmental control of motor coordination in insects.

    Location and major postembryonic changes of identified 5-HT-immunoreactive neurones in the terminal ganglion of a cricket (Acheta domesticus) (1986)
    Springer
    Cell & tissue research 245 (1986), S. 615-621

    ISSN: 1432-0878
    Schlagwort(e): 5-HT ; Insect neurones ; Terminal ganglion ; Sexual dimorphism ; Developmental changes ; Cricket, Acheta domesticus

    Notizen: Summary In the terminal ganglion of the cricket, Acheta domesticus, the somata of certain interneurones and efferent neurones consistently react to 5-HT immunohistochemistry. There are serially homologous pairs of bilateral interneurones seen in the neuromeres of the 7th to the 10th segment and hindgut neurones with their somata located at the posterior median end of the ganglion. In adult crickets, pairs of large efferent neurones with lateral somata supply specific genital muscles in the 8th and the 9th segment of females. In males, only one pair of these efferent neurones supplies genital muscles of the 9th segment only. These identified 5-HT-immunoreactive neurones are not detected in larval crickets before development of the genital apparatus.
