* the nervous system (of vertebrates) comprises a central division (skull & vertebral column) and a peripheral division (nerves & ganglia) * the rostro-(cid:272)audal (cid:862)(cid:374)eu(cid:396)oa(cid:454)is(cid:863) of (cid:395)uad(cid:396)upeds is esse(cid:374)tiall(cid:455) ho(cid:396)izo(cid:374)tal, so (cid:862)up(cid:863) a(cid:374)d (cid:862)do(cid:449)(cid:374)(cid:863) directions are dorsal and ventral rostral towards head.
