Cerebral ventricles

ventricles o ka lolo - he lua ke aupuni 'ia ma nā mea a pau o kona Oihana. Ka mea, i piha me ka loli (spinal). Ventricles o ka lolo - loko mai o ke kino cavities haumāna Oe. Ka loko ili o ka pā uhi ependyma. Līkaia waleʻehā ventricle.

Mua a me ka lua o ka hema-pono symmetric, a ma na cavities e hemispheres. Mau lolo ventricles i ka hooponopono ia ma ke kino callosum ma ka mānoanoa o cerebral keʻokeʻo mea. Ma kēlā me kēia no kēia mau eha mau mea i kaha. Ke narrowest, ke kikowaena hapa o Nyos i loko o ka parietal lobe. Ua apo ai i thalamus luna a me ka neʻe aku i hiki i ka mea mua pepeiaohao anteriorly i loko o ka posterior pu ia ma ka hope, a e kō ana i ka lalo ventricle pu. Anterior pepeiaohao o Nyos i loko o ka frontal lobe, occipital pepeiaohao o ka hope, lalo pepeiaohao moe i loko o ke kino lobe. Ke kīloi paʻewa symmetrical lolo ventricles i hookaawale ia e ke aniani moakaka mua pā pōhaku. Ua he o nā papaʻelua.

Kākau kēlā me kēia mua o ke kolu o ka ventricle ua hana ka hoʻohana 'ana interventricular puka. Ma ka medialʻaoʻao vascular plexus hana e holo ana ma ke kikowaena hapa. Ua Ua hanaʻia ma ka mea o cerebral vascularʻili lahilahi hapa e protrudes ma ka lalo pū symmetrical ventricles. Vascular plexus o ke kīloi paʻewa, a kolu ventricles i hoike hoʻohana 'ana i ka interventricular lua.

Ke kolu o ka ventricle o ka lua i loko o ka diencephalon. He ua poe ia e kekahi wahi paiki slit-e like kahua, ua aia i loko o ka sagittal pelane.

Konaʻaoʻao paia i hanaʻia e ka medial haʻawina o ka thalamus, ka lalo - ka hypothalamus. Front ventricle ua kau palena ia ma lalo nei ma ka lahilahi papa, maalo ae la oia upwardly ma kolamu e pio. Kona hope paia juts mai ma kona haʻahaʻa kuleana i loko o ka caudal kuhikuhi, ho okumu i nadshishkovidnoe recess. Ma luna o ke kolu o ka ventricle ua moe ma ke kino callosum, a me ka lolo vault. Kēia pā Ua hana vascular plexus manawa. Ka lua höʻike posteriorly ma ka lolo ka wai, i mea i ka wa i loko o ka midbrain, a hoʻohuiʻia ke kolu o ventricle me ka ha.

IV ventricle - ka lua o ka medulla oblongata a me ke alahaka, (ma ka embryogenesis hindbrain). Rhomboid fossa o kona lalo. Over ka ha o ventricle o ka cerebellum. Kona hale e like me ka nū'ōlelo halelewa. Chutes (lolo holo hou aku i) - anuanu lolo waiwai. Kekahi o nā aliʻi no ka holo (keena) tensioned ma waena o cerebellar wāwae (luna) a me kona mauʻano i ka hope maluna māhele o ka hale. Ka hope o lalo loa ua hana ia e kekahi lalo ramp. Ua ua pili i ka lalo wāwae, a lobule (hamoʻia) o ka cerebellum. United luna o ka pea, ho okumu i ka huina nei iluna i loko o ia.

Ka haahaa hene o ka loko kumu o ka ha o ka ventricle e pili vascular nenoaiu. Ke vascular i ka pūhaka hanauna o cerebrospinal loli. I ka lua a me ka spinal ke kaula Kanal, e like me ka rhomboid fossa i loko o ka'āina o kona lalo kihi.

Ka hope haahaa hapa o ka hale, he ekolu puka. Middle, o ka mea nui loa, aia i loko o ke kikowaena hapa o ka lalo hene. Ma ka māhele o ke kīloi paʻewa kihi o ka rhomboid i loko o ka fossa eʻaoʻao puka. Ma kēia mau puka ua lawe mai kamailio ma waena o ka ventricular lua, a me ka subarachnoid puni.

No kekahi o na anomalies, hoʻonāukiukiʻana mai o ka hooulu ana o ka helu ana o na maʻi e pili asymmetry o ka lolo ventricles. He He pinepineʻike, a me ka māhuahua intracranial puʻe. Ka loaʻaʻana o keia ano hiki i ka hōʻike i ke alo o ka loloʻeho a maloko hydrocephalus (hypertensive-hydrocephalic maʻi pale). Ma kēia manaʻo pili i ka luna 'o symptoms i ke kumu no deformation (nā loko, a mai) a precipitating māhuahua lolo ventricles.
