Ubuchopho bomntu

Ubuchopho bomntu kunye ijikelezisa benkqubo yayo luvo. Kuzalwa ubunzima balo ayidluli 330 okanye 340 grams. Kwinqanaba le umbungu kunye kwiminyaka embalwa yokuqala ebuntwaneni, ingqondo yomntu yokuzenzela ngokuzimisela. Iminyaka 20 ukukhula kwayo sele kugqityiwe. Umntu omdala ubunzima ubuchopho eyindoda 1375 g, yaye umfazi - 1275 umzimba ubunzima Ngaphantsi kumntu wesini wamhle ngenxa yobukhulu yabo yonke ezincinane. A mass liyancipha kunye nobudala, kungekhona nje onke amalungu, ukulahlekelwa ubunzima kunye nobuchopho.

Anatomy of ngaye, kunye nokusebenza sifundwa yeenkqubo zengqondo - ingqeqesho kwenkqubo peripheral Wayesoyika central.

Singene ekhanda ingqondo yomntu kwisisu cranial. Luquka ezi zifaka yobuchopho kunye kwiCerebellum kunye umphanda.

Idla ubuchopho ngamaqela amahlanu: onesiphelo ingqondo, embindini, ngomva, eliphakathi elide. Yiya zingahlala sisichazela ngqo kwi umnqonqo. Ukuqhuba isabelo yayo intamo Medulla. ukwakheka kwalo ifana ibhalbhu evuthelweyo. Yaye ke inxenye engentla Oblongata Medulla udlula ngasemva, equka kwiCerebellum kunye kwebhulorho. umcimbi izimvi zakhe kwenza iziqithi ngamnye - nuclei luvo cranial - iintsika hayi eziqinileyo njengoko apha emqolo. Kwakhona unalo enemingxuma ukuyilwa inkqubo efanelekileyo, iiseli ezihambelanayo zemithambo. Ibhulorho ifana irola eyakhiwa luvo. Inxalenye emva kwayo azigubungela lo mbandela ezingwevu ngohlobo eziba kwimithambo- cranial. Xa ekugqibeleni linciphise kwaye iphela embindini kwiCerebellum, leyo, ukuba kwi-Pons kunye Medulla Oblongata, azivalele kubo phantse ngokupheleleyo. Ukusuka ngaphezu kokuba wayifulela umcimbi engwevu vee yahlulwe yaba komsindo.

Obuphakathi ngaphesheya siqwenga eqhagamshelwe ngasemva. Oku kuquka imilenze kunye namaqumrhu quadrigeminal. Eli gama nembasa, uphahla ifumene ukuba ukwahlulwa ibe ezimbini encotsheni yenduli, ezinxulumene ngombono, kwaye zimbini zingentla ezinxulumene kukuva. Icandelo umnqamlezo ephakathi Sisiseko imilenze ingqondo ivili kunye nophahla. Phakathi imilenze kunye nophahla kulele wechibi lobuchopho. Ivili iqulethe ukusekwa reticular kunye kwahlelwa ezimbini enkulu ebomvu.

Phantsi I-corpus na ke ephakathi, ophezu emacaleni iifyuzi kunye zifaka lobuchopho. It has entabeni ezine: ezibonwayo, zabugornom indawo nadbugornuyu kunye podbugornuyu. Uvuleke diencephalon - le ventricle wesithathu.

neuron Human ebuchotsheni ivela njenge umcimbi gray ukuyigubungela ikhweyitha nokuba ubukhulu we-5 mm. Ukusukela luvo yalo kunye neeseli (iiseli zemithambo-luvo), apho ulalelwe ngomaleko ngendlela ethile. Iqolo mixed. inxalenye nganye lwesakhiwo yalo imicu ezahlukeneyo kunye neeseli. Oku kungenxa imisebenzi lenza. Enyanisweni inxenye nganye yobuchopho ngokwahlukileyo ifumana pulses ekufikeleleni phezu umzimba uphela izicwili kunye namaziko. Umzekelo, indlela lwemiqondiso ekuva kunqunyanyiswa kwi nomhlehlo zezomzuzwana, ezibonwayo - yaye neuron Occipital njl amaSebe yena thumela la kwezinye iisayithi yayo esikhondweni ebuchotsheni ...

Ukongezelela, ingqondo yomntu, ngokunjalo amanakani, ehlanganiswa amaqokobhe ezintathu: olujikeleza (athambileyo), arachnoid ijiye. Le periosteum emathanjeni ukhakhayi - oku iqokobhe nzima. Kumphezulu ingqondo a ibhityile, hayi equlethe imithambo yegazi arachnoid. A koko ingqondo, neempahla kwaye iqulathe soft kakhulu, elikuvumela ukuba ugcwalise zonke kwimijelo kunye noqhoqhoqho ebuchotsheni. Ngaphandle akunakwenzeka lokusekwa plexus nemithambo ye ventricles.

Ekubeni umnqonqo kwaye nobuchopho ezihambelanayo, ukusilela womnye kubo ngokuyimfuneko kukhokelela ukuhlukumeza ikhaliphe, nenoxanduva enye. ukonakala kwengqondo kunye ukudinwa nokuba banda, nokudinwa kwemisebenzi kungakhokelela kwizifo kakhulu kwinkqubo luvo obuntu.
