[Bgee_curator][VHOG] UBERON:0003291 MA:0000987 In fishes, the meninges consist of a single membrane, the primitive meninx, wrapped around the brain and spinal cord. With the adoption of terrestrial life, the meninges doubled. In amphibians, reptiles, and birds, the meninges include a thick outer dura mater derived from mesoderm and a thin inner secondary meninx. (...) In mammals, the dura mater persists, but division of the secondary meninx yields both the arachnoid and the pia mater from ectomesoderm.[well established][VHOG] consider changing genus to subdivision of meninx rhomencephalon meninges EHDAA:3688 meninges of hindbrain hindbrain meninx EMAPA:17783 A meninx that is part of a hindbrain [Automatically generated definition].
