Kwararrun kwakwalwa sune cavities hudu da ke cikin kwakwalwa wanda ke dauke da kwayar cutar ta jiki (CSF) . Akwai hanyoyi guda biyu na kwakwalwa - daya a kowane gefen ƙwayar cizon sauro. Harkokin kwakwalwa na waje suna ci gaba da ci gaba da ƙwararrun ƙwararrun ƙwararrun, wanda shine ƙananan cikin kwakwalwa. Harshen na uku na ci gaba da ci gaba tare da kashi huɗu na ventricle, wanda ke gudana tare da kwakwalwa.
Harkokin ventricles duk wani ɓangare ne na "tsarin ventricular." Harkokin ventricles suna haɗuwa da juna, kuma tare da tsakiya na tsakiya na ƙananan baya kuma tare da sararin subarachnoid (sarari a tsakanin ɗayan linzami guda biyu da ke rarrabe kwakwalwa daga kwanyar). Kamfanin CSF ya samo asali ne daga madaurin ventricles. Bayanan CSF ya kewaya a cikin tsarin ventricular kuma an sake komawa cikin sararin subarachnoid.
Muhimmanci
Hanyoyin da ke tattare da magunguna suna da mahimmanci ga al'amuran al'ada ta tsakiya. Yana kare kwakwalwa ta hanyar barin shi "tasowa" a cikin wanka mai ruwa kuma yana samar da haɗari mai ban tsoro a kan rauni. CSF kanta ma yana taimakawa wajen samar da kayan abinci zuwa kwakwalwa da kuma ci gaba da kwakwalwa a ma'auni.
Matsaloli na Amfani
Tsarin gwaninta zuwa CSF yana sa matsa lamba ya tashi cikin tsarin ventricular kuma zai iya samar da hydrocephalus.
Kamuwa (kamar meningitis ) ko zub da jini zai iya canza dabi'un CSF. Kullin lumbar (LP), wanda ake kira tafin kashin baya, za'a iya amfani dashi don auna ƙwaƙwalwar a ciki a cikin canji na kashin baya, kuma don gwada CSF akan alamun kamuwa da cuta, kumburi, ko nakasa.
LP yana da mahimmanci sosai don bincikar cututtuka na tsarin kulawa na tsakiya.
Alal misali, a cikin cutar jini , CT scan zai iya zama al'ada, amma LP zai bayyana jini a cikin CSF.
