Chepfungwa ventricles

ventricles uropi - a mhango yaiva ose mumadhipatimendi aro. Vari vakazadzwa Urume (musana). Ventricles uropi - zvinobva muviri in yechipiri sefuro. Yomukati penyika masvingo akafukidza ependyma. Govera mana chete ventricle.

First uye kuruboshwe-kurudyi symmetric wechipiri, uye ari in vari hemispheres. Izvi ventricles uropi vanosarudzirwa panguva yacho corpus callosum mu Ukobvu chepfungwa chena nyaya. In nechimwe izvi munzvimbo zvina anozivikanwa. The narrowest, musimboti chikamu iri mune parietal akafukidza. It dzinenge dziine thalamus pamusoro uye inofamba ichienda nyanga pamberi anteriorly mu posterior hwamanda negotsi downwards kusvika rezasi ventricle runyanga. runyanga Anterior riri mune frontal akafukidza, occipital runyanga ari shure, pasi nyanga iri zvenyama akafukidza. The lateral zvakafanana, ichibata pfungwa ventricles vanoparadzaniswa ne segirazi rusvingo mberi. Inoitwa kwamahwendefa maviri.

Post nomumwe pamberi rechitatu ventricle rinoitwa kushandisa interventricular buri. On the medial divi vascular plexus akaumba pakukoka nechepakati chikamu. It achiumbwa pachishandiswa chepfungwa vascular Kamudzira mugove kuti makabuda panzvimbo dzapasi nyanga zvakafanana, ichibata ventricles. Vascular plexus of lateral uye wechitatu ventricles vari akashuma kushandisa interventricular makomba.

Chechitatu ventricle ndiwo mhango ari diencephalon. Iye inomiririrwa rakamanikana mutswe-kufanana nzvimbo, iri munzvimbo sagittal ndege.

Its masvingo divi inoumbwa migove medial pamusoro thalamus, rezasi - the hypothalamus. Front ventricle iri rakatenderedzwa pazasi achishandisa bwendefa, kupfuura upwardly muzvikamu arch. rusvingo Its rwemberi juts kubva panguva mugove wayo yakaderera iri caudal mirayiridzo, pova nadshishkovidnoe rusesi. Above wechitatu ventricle iri bordered nokuda corpus callosum, uye pfungwa iyi. rusvingo urwu aumbwa vascular plexus hwaro. The mhango runoita posteriorly mumvura uropi, inova nzvimbo iri midbrain uye rinobatanidza ventricle wechitatu nechechina.

IV ventricle - munhu mhango of medulla oblongata uye zambuko (mu embryogenesis hindbrain). Rhomboid fossa chiri pasi. Pamusoro ventricle rwechina cerebellum. denga rayo sezvinoita mukoko tende. Chutes (uropi maseiri) - ndiro uropi fuma. Mumwe maseiri (rokumusoro) tensioned pakati makumbo cerebellar (yepamusoro) uye anoumba veshure yokumusoro munharaunda padenga. The rwemberi pasi chikamu inoumbwa yakaderera murwere. It wanamatira makumbo yakaderera uye lobule (chinyorwa) ari cerebellum. United pamusoro seiri, dzikaumba necheparutivi protrude mariri.

Rezasi yakatenuka nechomukati mujinga wechina ventricle pedyo vascular hurongwa. The vascular akaita chizvarwa mukobvu pamusoro cerebrospinal mvura. The mhango pamwe musana chiteshi maererano rhomboid fossa munzvimbo yayo ezasi wekona.

Zveshure repasi mugove reimba ane mawindo matatu. Middle, ndicho chikamu chikuru, iri nechepakati chikamu rezasi materu. Munzvimbo yacho lateral makona rhomboid iri fossa vari makomba divi. Kuburikidza mawindo izvi rinoitwa kutaurirana pakati ventricular mhango uye subarachnoid nzvimbo.

Nokuti mumwe anomalies, chinokurwadzai kukura dzinoverengeka zvirwere chokuita asymmetry uropi ventricles. Chinhu kakawanda chirwere uye kwakawedzera intracranial kuvafurira. Kuziva miedzo zvazvo izvi zvinogona anoratidzawo kuvapo rouropi kana womukati hydrocephalus (chirwere cheBP-hydrocephalic urwere). By pfungwa iyi zvinoreva kuzvivako zviratidzo chinokonzera deformation (zvose mukati nokunze) uye precipitating kuwedzera uropi ventricles.
