Ubuchopho bomuntu

Ubuchopho bomuntu kanye osebenzisa kwesistimu yayo sezinzwa. Ewusana olusanda kuzalwa isisindo sayo ingeqi 330 noma 340 amagremu. Ngesikhathi sigaba nele-embryo ne Eminyakeni lembalwa yekucala ebuntwaneni, ubuchopho bomuntu ethuthuka uye wakwenza ngokuzimisela. Iminyaka engu-20 ekukhuleni kwayo liyaphela. Umuntu omdala wesilisa ubuchopho isisindo kwaba 1375 g, nowesifazane - 1275 isisindo Ngaphansi umzimba kwabobulili bubuhle kuyinto ngenxa yobukhulu bawo jikelele ezincane. Sekucala incipha nobudala, hhayi kuphela zonke izitho, ukuncipha kanye nobuchopho.

Anatomy ngaye, ukusebenza sifundwa Neurology - isiyalo neuropathy isimiso sezinzwa futhi central.

It ithatha amabombo ubuchopho bomuntu ngalo ingaphakathi cranial. It siqukethe le ama- cerebral kanye cerebellum nge emgqonyeni.

Behlukene ebuchosheni yezigaba ezinhlanu: a ezilinganiselwe ubuchopho, maphakathi, posterior, Lesisemkhatsini eside. Iya kuhlale ibuthinta ngokuqondile ku emgogodleni. Kuchubeka intamo ingxenye kuyinto medulla. ezakheke ufana isibani side. Futhi engxenyeni engenhla oblongata medulla sihamba ngaphambili langemuva, ehlanganisa cerebellum futhi ibhuloho. ndaba zakhe ezimpunga yakha iziqhingi ngabanye - cranial ezinzwa nuclei - izinsika hhayi eliqinile njengoba emgogodleni. It Ubuye anezikhala kumiswa inqubo efanele, amaseli oxhumene kwemizwa. Ibhuloho lifana roller sakhiwa yezinzwa. Ingxenye ezingemuva ligcwale grey ndaba ngesimo le nuclei we izinzwa cranial. Ekupheleni-ke unciphise futhi iphela phakathi cerebellum, okuyinto, nokuba Pons futhi medulla oblongata, uvala kubo cishe ngokuphelele. Kusukela phezulu ke embozwe gray ndaba kanye anemifantu sehlukaniswe izingxenye.

Ubuchopho obuphakathi ukunqamula kulesi siqephu sezwe exhunywe kwi ezingemuva. Kuhlanganisa imilenze nemizimba quadrigeminal. Leli gama le ipuleti ophahleni lithole i-division zibe ezimbili esiqongweni sentaba, elihlobene ne umbono, futhi phansi ezimbili ezihambisana ngokuzwa. Ingxenye evundlile le ubuchopho obuphakathi kuyinto kumila imilenze ubuchopho isondo nophahla. Phakathi kwemilenze ophahleni amanga kunomsele palsy. A isondo iqukethe kumiswa reticular futhi nucleus ezimbili esikhulu esibomvu.

Ngaphansi callosum Corpus kuyinto le ubuchopho obuphakathi, okuyinto ku ezinhlangothini fuses ne ama- cerebral palsy. It has ezine egqumeni: ezibukwayo, zabugornom endaweni nadbugornuyu futhi podbugornuyu. Cavity diencephalon - ventricle lwesithathu.

Human cortex cerebral selivela grey ndaba usibekela Nenkabazwe nokuba ukushuba 5 mm. Ifomu ezinzwa yayo zemicu amaseli (izinzwa), okuyinto amanga in izingqimba ngendlela ethile. Amagxolo kuyinto edidayo. ingxenye ngayinye isakhiwo salo Imicu yotshani ezahlukene namaseli. Lokhu kungenxa imisebenzi ukuthi wenza. Empeleni ingxenye yobuchopho ngalunye ngokuhlukile uthola pulses kusuka ukufinyelela ezisebusweni bawo wonke umzimba kwezicubu eziyishumi nemitshingo. Ngokwesibonelo, indlela amasignali sokuzwa anqamule ku Lobe yesikhashana, ebonwayo - futhi cortex occipital njll iMinyango ithuba ukuthumela pulses kwamanye amasayithi yayo empandni ingqondo ...

Ngaphezu kwalokho, ingqondo yomuntu, kanye amaphiko, imbozwe amagobolondo ezintathu: semithambo (esithambile), arachnoid futhi eliqinile. I periosteum amathambo skull - lena igobolondo kanzima. Uma uyikha phezulu le zobuchopho kuyinto mncane, hhayi equkethe imithambo yegazi arachnoid. A ephambene ubuchopho, izitsha, kantsi sicuketse loku ethambile kakhulu, okuvumela ukuba ugcwalise zonke imisele kanye nobuchopho umqhewu. Ngaphandle akunakwenzeka ukwakheka plexus semithambo we ventricles.

Njengoba emgogodleni nobuchopho oxhumene, ukwehluleka omunye wabo ngempela kuholela ukuhlukumeza ikhaliphe, okuyinto unomthwalo omunye. ukulimala kobuchopho futhi ukukhathala ngisho yanda, ukukhathala imisebenzi kungaholela ezifweni ezibucayi isimiso sezinzwa esiyinhloko womuntu.
