I grey ndaba zobuchopho nomgogodla grey ndaba

Isimiso sezinzwa esiyinhloko kuba emgogodleni ingqondo. ketshezi ebuchosheni ngezithako zawo iyunifomu, ifomu yakhe engathí elimhlophe kanye grey. Okumhlophe yezinzwa, izinqubo zabo, ukuba, ngokulandelana, umbala omhlophe. Gray - yinhlanganisela ezinzwa nezinqubo kula maseli.

grey spinal

It kwakhiwa inombolo enkulu kakhulu ezintathu izinhlobo izinzwa, okuyinto zihlelwe zaba core: amaseli radicular ugongolo izinzwa amaseli kwangaphakathi. Kutholwe ngaphakathi futhi ezungezwe ndaba emhlophe. Kuyinto esithuthuke kabanzana ku wesibeletho kanye lumbar nomgogodla, okuyinto lihlotshaniswa ukwanda Izinzwa.

Maphakathi kukhona isiteshi emaphakathi eyehlayo ubude yonke we umgogodla, luyisici esisemqoka ke. Eziqukethwe isiteshi cerebrospinal fluid. Lizungezwe grey ndaba, okuthiwa Lesisemkhatsini. Lapha, le ndaba grey zingahlukaniswa zibe phambi ayiwele naye, ohlangothini futhi bakhulise abhanqiwe amakholomu. Ngakho, ngo-cross-section izimpondo basuke ezintathu: phambi, ohlangothini futhi bakhulise.

Ectocinerea

umgogodla sihamba ngaphandle noma yiziphi izinguquko kule oblongata medulla. Umngcele obakhiwa side futhi ngemuva okuyinto, iyindawo lapho zitholakala izimpande umbhangqwana wokuqala nezinzwa ka emgogodleni. Iminyango engxenyeni engenhla mkhulu kunokhalo phansi. Ngo ubuchopho, core side banesibopho ibhalansi, ukuhlobanisa izinto, umzimba, kwegazi nokuphefumula kwezimila. Obungemuva zimumethe izingxenye ezimbili: kwebhuloho kanye cerebellum.

Ibhuloho - roller ezimhlophe elise ngu base zobuchopho. Front ungabona komngcele imilenze ubuchopho, nengxenye yalo engemuva - kuya oblongata medulla. Ingxenye evundlile ibhekwa daba elimhlophe kanye grey-nucleus. Ukuqhubeka medulla iyona amaphiko ingxenye kwebhuloho, lapho nengaphakathi inzwa izinhlelo ahlelwe nezinzwa cranial. Lapha ubuswa grey ndaba zobuchopho. I cerebellum itholakala ngaphansi emuva zobuchopho. Siqukethe ama- futhi phakathi okuyingxenye - worm. Worm lebhokisi ama- ezimbili. ungqimba cerebellum ihlanganisa empunga endabeni cortex we cerebellum akha meanders. Ingqikithi ezimhlophe lingena gyrus. Ngenhla nesembozo zazo ezimpunga ndaba zobuchopho. kwesigaba-Picture-in kakhulu efana isihlahla.

Phakathi empunga ndaba we nuclei ezibaluleke kakhulu futhi okuphawulekayo kakhulu iqembu eliyinhloko elakha abomvu ukuthi wenza ayiphoyinti. Plumbing ubuchopho obuphakathi - isiteshi ewumngcingo nge ubude ngamasentimitha amabili. It lebhokisi ventricles, sesithathu nesesine. ' Lesi siteshi izungeza grey ndaba zobuchopho, okuyinto ephakathi ehlanganisa amaseli encane. I Lesisemkhatsini ubuchopho ndaba siqukethe nuclei okuqondene izikhungo elise ngaphansi kuqweqwe, futhi unesibopho zonke izinhlobo ukuzwela. Telencephalon, ke inezingxenye ezimbili, ama- ezimbili. Cortex cerebral zobuchopho grey ndaba ngesimo ipuleti mncane. Lakhiwa amangqamuzana ezinzwa izinombolo ezinkulu. La mangqamuzana zingahlukaniswa zibe izingqimba. ugqinsi ngalunye, esikhundleni salokho, inezici ezithile esivela kuwo.

Ngakho, grey ndaba - lokhu assemblage sezinzwa dendrites. Ukuminyana kwenzeka ohlelweni sezinzwa, akha umgogodla kanye nobuchopho. Lokhu kwaziswa yakha cortex cerebral kanye nuclei subcortical. kwakhiwa Into emgogodleni is by amangqamuzana ezinzwa, zazo zikhona abangaba yizigidi ezingu-nantathu. Umthamo grey okumunyethwe ubuchopho uyakwazi ukuthonya ezingeni ekukhuleni. Kulindeleke ukucutshungulwa ukuthi isamba esengeziwe sika-grey ndaba kakhulu ngokushesha ulwazi.
