20.500.12556/DiRROS-20009 The subgenual organ complex in the cave cricket Troglophilus neglectus (Orthoptera: Rhaphidophoridae) comparative innervation and sensory evolution Comparative studies of the organization of nervous systems and sensory organs can reveal their evolution and specific adaptations. In the forelegs of some Ensifera (including crickets and tettigoniids), tympanal hearing organs are located in close proximity to the mechanosensitive subgenual organ (SGO). In the present study, the SGO complex in the non-hearing cave cricket Troglophilus neglectus (Rhaphidophoridae) is investigated for the neuronal innervation pattern and for organs homologous to the hearing organs in related taxa. We analyse the innervation pattern of the sensory organs (SGO and intermediate organ (IO)) and its variability between individuals. In T. neglectus, the IO consists of two major groups of closely associated sensilla with different positions. While the distal-most sensilla superficially resemble tettigoniid auditory sensilla in location and orientation, the sensory innervation does not show these two groups to be distinct organs. Though variability in the number of sensory nerve branches occurs, usually either organ is supplied by a single nerve branch. Hence, no sensory elements clearly homologous to the auditory organ are evident. In contrast to other non-hearing Ensifera, the cave cricket sensory structures are relatively simple, consistent with a plesiomorphic organization resembling sensory innervation in grasshoppers and stick insects. neuroanatomy chordotonal organ mechanoreceptor sensory innervation neural phylogeny true false true Angleški jezik Ni določen Neznano 2024-08-02 08:32:22 2024-08-02 08:32:22 2024-08-03 03:45:58 0000-00-00 00:00:00 2014 0 0 Nasl. z nasl. zaslona; Opis vira z dne 7. 10. 2014; str. 1-14 Vol. 1 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2014-10-01 591.5 2054-5703 10.1098/rsos.140240 3221583 http://rsos.royalsocietypublishing.org/content/royopensci/1/2/140240.full.pdf 1 36dcb0c8-5088-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27825 RAZ_Strauß_Johannes_2014.pdf RAZ_Strauß_Johannes_2014.pdf 1 E0B268A7001487CD39586CAB0FD7742F 0978e64dd1a115734016416d4c7e774b6ec1ab37e154595559e666e14d55a6c5 86ab2fe2-5088-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27826 https://doi.org/10.1098/rsos.140240 0 987e1bb1-5088-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27827 Nacionalni inštitut za biologijo 0 0 0
