Isakhiwo ingqondo. Pons

Kuzo zonke iinkqubo kwenkqubo luvo komzimba iye endaweni ekhethekileyo. Ubuchopho ulawula yonke imisebenzi, nto leyo sinikezwe nendoda. Ngenxa kuye, Wenza ubudlelwane phakathi umsebenzi amalungu kunye neenkqubo. Ngaphandle kokuba ummiselo lomntu ingqondo ubengayi kukha abe ekhoyo iphila. Ngenxa umsebenzi eququzelelweyo kwenkqubo luvo, sisiya, ukuthetha, ukucinga kwaye ndiziva ezenzeka ngaphandle. Kobuchopho isakhiwo entsonkothileyo, ngamnye yeencindi linoxanduva umsebenzi okhethekileyo. Kunjalo, izakhiwo umsebenzi wayo zinika umzimba wethu kuphela kumanqaku ewonke afunyenwe ngumviwa. Ingakumbi ke ukubaluleka kwemfundo, amalungu inkqubo luvo zezona Medulla kunye Pons. Bona ziqulathe Amaziko ezisisiseko kubalulekile (sentliziyo, ezokuphefumla, khohlo, slozootdelitelny), kwakunye kunokubangela kuninzi luvo cranial.

Ubume yobuchopho

Iyunithi noshowo inkqubo luvo i neuron. Yiyo le seli linoxanduva ulwamkelo, ukwenziwa nokugcinwa kweenkcukacha. Yonke le Ubuchopho bomntu yeyona Sisihloko luvo kunye neenkqubo zabo - axons kunye luvo. Bathi ziqinisekise ukuba iziganeko kwi CNS yaye kuloo maziko. Ubuchopho ubunjwe engwevu into emhlophe. Eyokuqala bangazenzela iiseli zemithambo-luvo, indlela yesibini - axons zabo. Iziseko eziphambili zezi ingqondo ikhweyitha (ekhohlo nasekunene), kwiCerebellum kunye buti. Eyokuqala unoxanduva ingqondo yomntu, inkumbulo yakhe, ukucinga, lengqondo. ngokukodwa, kwiCerebellum kubalulekile ukuba kuququzelelo weenjini, oko kwenza kanye ukuma, ukuhamba, uthabathe izinto. Pons elise ngaphantsi. Nguye unxulumano phakathi Medulla kunye kwiCerebellum.

Pons: isakhiwo kunye nokusebenza

Ibhulorho yenye amalungu obuchopho. ubude bayo kuyahluka 2.4 ukuya 2.6 cm Pons enobunzima malunga 7 izakhiwo g leyo abut nayo, -. Ingaba lume kwaye obuphakathi eka ezinqamlezayo. Iinkalo eziphambili zezi Pons aphezulu ophakathi peduncles cerebellar izeziphi iindlela eziphambili. Front nguye emseleni basilar, equlethe imithambo ngokunikezela ingqondo, kwaye ibekwe ecaleni kwisiza uphume ye-luvo trigeminal. Ezomva iifom Pons inxalenye engentla mingxuma rhomboid apho yafakwa 6 kunye nesabelo 7 kwimithambo- cranial. Phezulu kwe bhulorho kukho ezininzi umphakathi (5, 6, 7, 8). Emazantsi kwebhulorho uqhuba phezulu-phantsi ndlela: corticospinal, bulbar kunye umendo ukupheyiva.

Eyona umsebenzi kulo mzimba:

1. Umqhubi - ngokweendlela zakhe zizimvo zemithambo ukuya neuron kunye umnqonqo.
2. Touch umsebenzi - ibonelelwa luvo vestibular-cochlear kunye trigeminal. Xa eziba kwi-luvo 8 cranial kwenzeka ulwazi processing malunga yashukunyiswa vestibular.
3. Motor - inika ukuncitshiswa zonke imisipha yobuso. Oku kungenxa eziba kwi-luvo trigeminal. Ukongeza, inxalenye yayo ezibuthathaka ifumana inkcazelo evela kwiinwebu receptors emlonyeni ukhozo lweliso lasentloko kunye kwamazinyo. Ezi Imiqondiso zithunyelwa kwi ifayibha kwebhulorho kwi neuron.
4. umsebenzi ezimanyanisayo ibonelela ngekhonkco phakathi ngaphambili nobuchopho diff.
5. Ikhaliphe le Brain.

kumiswa Reticular kwe bhulorho

ukubunjwa Reticular - umxokelelwane branched, ibekwe ebuchotsheni, eliquka iiseli zemithambo-luvo kunye nuclei. Iyafumaneka phantse yonke CNS namaqonga kakuhle enambuzelayo ukusuka kwelinye isebe ukuya kwelinye. ukubunjwa nakwiPontine reticular zilahlwa phakathi evuthelweyo kunye ephakathi. iinkqubo elide - axons benza into eqinileyo abamhlophe sihambe ngendlela kwiCerebellum. Ukongeza, ezi Imicu iiseli zemithambo-luvo iziganeko ibhulorho nga kudluliselwa ukusuka intloko umva. Ukongeza, ukuyilwa reticular edlulisela imiqondiso ukuya neuron, ngoko ukuba kukho yokuvusa iphupha yabantu. Iinkozo zifumaneka kule nxalenye bhulorho, jonga kwiziko zokuphefumla ibekwe kwi Oblongata Medulla.

Reflex umsebenzi ibhulorho

Ukukwazi kwenkqubo luvo ukusabela kwizinto ezingaphandle ubizwa ngokuba reflex. Umzekelo xa kukuvela izinkcwe kwi emehlweni ukutya, umnqweno ukuya ngokulala umculo isandi oludambisa njalo njalo. G. Cerebral ikhaliphe kunokuba enemiqathango kunye kwemibandela. Owokuqala umntu ofumana ngexesha lobomi, ukuba ingaba mihle okanye ingalungelelaniswa kuxhomekeka iminqweno yethu. Le yokugqibela ayikwazi kuba ezingqondweni, ukuba elungiselwe kunye ngokuzalwa, kwaye ayikwazi ukuba ilungiswe. Oku kuquka ukuhlafuna igwinya, ukuqonda kunye nezinye ingqondo.

Njengoko ibhulorho kuchaphazela ukuvela ingqondo

Ngenxa yokuba i-Pons yinxalenye quadrigemina, iyasebenza kuphuhliso yokuva reflex manani. Ngenxa yokugqibela, siyakwazi ukugcina umzimba kwindawo ethile. Ukongeza, Ngokusebenza kunye ubuchopho lesibini, oko evala inxalenye enkulu ingqondo kwezihlunu.
