Efferent arteries of the prosomal ganglion in B. granulatus . A: Surface renderings of the neurilemma (Nl, transparent), the cerebral vasculature, and certain neuropils showing the frontal collection artery (Fca) and the pedipalpocoxal arteries (Pc); in anterior view. B: Surface renderings of the neurilemma (Nl), the cerebral vasculature, and certain neuropils showing the lateral collection artery (Lca); in anterolateral view; arrowhead indicates the position where the lateral collection artery (Lca) enters the frontal collection artery. C: Surface renderings of the neurilemma (Nl), the cerebral vasculature, and certain neuropils showing the ventral collection arteries (dashed white lines) and the efferent coxal arteries (CaI + IV); in ventral view. D: Schematic drawing of the ventral collection arteries (Vca), ventral neuropils (Vnp), and ventral efferent vessels; in dorsal view. Abbreviations: CaI, coxapophysal artery I; CaIV, coxal artery IV; Cca, central collection artery; Cn, cheliceral nerve; Fca, frontal collection artery; Lca, lateral collection artery; Nl, neurilemma; NpI + II, neuropil of leg I + II neuromere; Pc, pedipalpocoxal arteries; Pnp, posterior neuropils; Ppn, neuropil of pedipalpal neuromere; Tga, transganglionic artery; Vca, ventral collection arteries; Vnp, ventral neuropils.
