5-HT-immunoreactivity in Entobdella soleae was found to be extensive throughout both the central and peripheral nervous systems, with the strongest staining occurring in the innervation of the forebody, most notably in the paired cerebral ganglia, pharynx and adhesive pads. In the reproductive system, staining was evident throughout the numerous cell bodies and fibres innervating the musculature of the egg-assembly apparatus. The haptor contained an extensive array of serotoninergic fibres derived from the main longitudinal cords; this array was associated with the haptoral muscles and sclerites, and possibly with the ventral sensory papillae.
