Synganglion Histology of the Camel Tick Hyalomma Dromedarii (Acari: Ixodoidea: Ixodidae)

Abstract

The synganglion histology in female H. dromedarii is described and compared with other ticks. The synganglion, lying in a periganglionic blood sinus, is formed by a fused supra-esophageal part protocerebrum, cheliceral ganglia, pedipalpal ganglia and stomodeal pons) and a subesophageal part (4 pairs of pedal ganglia and the complex opisthosomatic ganglion). The synganglion is enclosed within a connective tissue sheath, the neurilemma. The perineurium underlies the neurilemma and is followed by the cortical region, which is separated from the neuropile by the subperineurium. Association, motor and neurosecretory cell types are the neurons which together with 4 or 5 glial cell types, compose the cortical zone of the synganglion. The fifth glial cell type is only distributed in the perineurium. Five levels of fibrous horizontal connectives and vertical commissures occur in the neuropile. Reprints.
