Structure of identified neurons innervating the lateral cardiac nerve cords in the migratory locust, Locusta migratoria migratorioides (Reiche and Fairmaire) (Orthoptera, Acrididae)
Our knowledge about the morphology of neurons innervating the lateral cardiac nerve cords (LCNCs) in migratory locusts, Locusta migratoria migratorioides (R. and F.) (Orthoptera, Acrididae) has increased considerably during recent years, mainly owing to immunocytochemical studies using antisera directed against members of insect neuropeptide families. In principle, there are three morphological types of neurons located within the CNS, which innervate the LCNCs in locusts: abdominal ganglia contain (i) bilaterally projecting, possibly unpaired neurons (BPNs) and (ii) paired, unilaterally projecting neurons. In addition, (iii) the LCNCs receive innervation from a pair of neurons, which is located within the suboesophageal ganglion. The axons of all three types of neurons project into the LCNCs via the segmental heart nerves, the most distal extensions of the dorsal segemental nerves of abdominal ganglia. When estimating the number of axons contained in one segmental heart nerve and formed by all central neurons so far identified, this number exceeds the number of axon profiles previously seen using the electron microscope. This indicates that most, or perhaps all central neurons projecting into the LCNCs, have been identified in these insects.
