Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mhenyu dzinosanganisira zvikamu zvitatu zvinofukidza uye zvinodzivirira uropi nomuzongoza (central nervous system) pamwe chete necerebrospinal fluid. Pia mater inenge iri membrane isina mvura inonamira zvikuru iyo inonamatira zvakasimba kumusoro kwouropi, ichitevera mativi ose maduku. Arachnoid mater (yakatumidzwa kudaro nemhaka yechimiro chayo chakafanana netambo yesarava) iri homwe yakasununguka pamusoro pepia mater. Nzvimbo inonzi subarachnoid space inoparadzanisa arachnoid uye pia mater membranes uye inozadzwa necerebrospinal fluid. Chikanda chokunze, dura mater, chikanda chakakora chinogara kwenguva refu, icho chakanamatira kumakenduru epachipfuva nepachipfuva.  Mubvunzo: Chii chinonzi membrane yakabatana nenzvimbo mbiri dzedehenya?
