Summary[edit]

Description
English: Carinella speciosa (=Tubulanus polymorphus; Nemertea: Paleonemertea: Tubulanidae). Portion of a transverse section through the brain region. The relation of the dorsal ganglion (dg) with the highly specialized cerebral sense organ (cso) is indicated. The ciliated canal (cc) of the sense organ connects directly with the exterior by a narrow tube (sop) – shown in dotted lines in the drawing, because it lies mainly in another section – opening on the lateral margin of the head. Several nerves (sn) are seen to pass from the dorsal ganglion to the sense organ. Only a small of the integumenal gland cells are shown. See also standard abbreviation.
