Figure 8From: The songbird syrinx morphome: a three-dimensional, high-resolution, interactive morphological map of the zebra finch vocal organSyringeal muscles and their attachment sites in the male and female zebra finch syrinx morphome. (A) Ventral view of the male zebra finch syrinx morphome based on an iodine-stained μCT scan showing muscles, bones, cartilaginous pads, and sound-producing labia. (B) Ventro-lateral view with transparent right ventral muscles VS and SVTB, revealing the underlying DVTB. (C) Attachment sites of the syringeal muscles seen from ventral and (D) ventro-lateral. The dotted line indicates the location of the CASM on which several muscles insert. (E) Dorsal view of the male zebra finch syrinx morphome. (F) Ventro-lateral view with transparent right dorsal muscles SVTB and LDS, revealing the DDS and DVTB. (G) Attachment sites of the syringeal muscles seen from dorsal and (H) dorso-lateral. (I) Ventral view of the female zebra finch syrinx morphome showing muscles, bones, cartilaginous pads and sound-producing labia. The muscles VS, SVTB and DVTB on the right hemisyrinx are transparent. (J) Dorsal view with left MDS and DTB transparent. (K) Muscle attachment sites seen from ventro-lateral and (L) dorso-lateral view. Abbreviations as listed in Table 1. DDS: yellow; DTB: orange; DVTB: dark green; LDS: neon green; MDS: violet; ST: blue; STB: cyan; SVTB: light green; VS: purple.Back to article page
