From: Innervation of the lophophore suggests that the phoronid Phoronis ovalis is a link between phoronids and bryozoans

Figure 8

Schemes of the organization of the lophophore nervous system in phoronids and bryozoans. Schemes are based on: Phoronis ovalis – herein, juvenile phoronids –20,21, adult phoronids –22,23,24,26, generalized bryozoa –6,17,31,32,33,34,35,36,37,38,39. In all schemes, the oral side is to the down, the anal side is at the top. Nerve elements, which are supposed to be homologous, are done in the same color. Color table: yellow – inner nerve center (cerebral ganglion – in bryozoa; and inner ganglion – in Phoronis ovalis), orange – dorsal ganglion, cyan – inner nerve ring, magenta – outer nerve ring, green – laterofrontal nerves of tentacles, pink – frontal nerves of tentacle, blue – abfrontal nerves on tentacle, white – inter-tentacular sensory cell, red – subperitoneal neurites, black – mouth and anus.
