Term information



latin term
dura mater cranialis [ FMA:TA FMA:71236 ]

external definition

The outermost and densest membrane of the three mammalian meninges covering the brain and spinal cord. [Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier, adapted_from_Dorian_AF][VHOG]

homology notes

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]
