A: Surface renderings of the anterior aorta system and the prosomal ganglion (Pg; yellow) showing general branching pattern of anterior aorta system; in anterolateral view. B: Surface renderings of the anterior aorta (Ao), branching arteries (e.g. cheliceral arteries, Ch), and the cerebral vasculature (Cv); in dorsal view. C: Surface renderings of the anterior aorta system and the prosomal ganglion (Pg; yellow) showing general branching pattern of prosomal arteries; in lateral view. D: Volume rendering of the ganglionic midline arteries in lateral view; asterisks indicating the eight transganglionic arteries (Tga); in lateral view. E: Schematic drawing of the prosomal vascular system (red) and the main afferent arteries (orange) of the prosomal ganglion; numbers denote transganglionic arteries 1-8.
