Figure 5From: The nervous system of Isodiametra pulchra (Acoela) with a discussion on the neuroanatomy of the Xenacoelomorpha and its evolutionary implicationsWhole mount stained with antibodies against tyrosinated tubulin (green: A, B, C, D, E), serotonin (polyclonal; magenta: A, B, C, D, E), and fluorophore-tagged phalloidin (blue: A, B). A. Projection of central sections. Arrowheads point to neurites that follow distinct inner muscles. B. Projection of ventral sections. Arrowheads point to neurites that follow distinct inner muscles. Asterisk marks position of statocyst. C. Projection of dorsal sections. D. Projection of central sections. Asterisk marks position of statocyst. E. Magnification of D.
