[Sensory innervation of the somite in the polychaete worm Nephthys hombergii].
Studies have been made on the peripheral sensory innervation of N. hombergii stained with methylene blue. It was shown that sensory elements of the polychaete are presented by several types of nervous cells which are symmetrically embedded between the circular and longitudinal muscle layers in each of the segments. Peripheral projections of these cells terminate in the epithelium, on muscle fibers and in the connective tissue. Central projections pass to the abdominal nerve chain. All. the observed sensory cells have a constant localization and shape, the latter presumably being determined by their polyvalent functions.
