Bird ubuchopho: isakhiwo kunye nokusebenza

Ubuchopho - umlawuli engundoqo zonke izinto ezisebenzayo kumzimba, kwakunye izenzo zayo zokuziphatha ezijoliswe sivumelane iimeko zangaphandle zobomi.

Medulla Oblongata i phambili umnqonqo. It has into grey ngaphandle kunye okumhlophe ibekwe ngaphakathi. Intlanganisela imizimba iseli zemithambo-luvo kwi Medulla ukuba kuba ngundoqo. Medulla - ilungu elibalulekileyo. Boyise yakhe lunyhasho izenzo reflex somatic kunye yawo ukufa kwenzeka ekutshatyalalisweni kwayo. Medulla wenza imisebenzi introducer kunye reflex. Ubuchopho ilawula ingqondo zilandelayo: kwentliziyo, imvakalozwi semithambo, ukuphefumla, ukukhohlela, uthimla, ukuvuza izinkcwe, yokuginya, secretion esiswini kunye pancreatic, ukugabha, metabolic, kujuba odanyazayo nokuvala isiciko, tonic ingqondo kwezihlunu skeletal.

Ngenxa imisebenzi kumaziko Medulla ukubonakalalisa obandayo ingqondo ukuma ezinxulumene. ikhaliphe oma abo ikhaliphe ezibangela nokunikezelwa ithoni izihlunu ngokuguqula indawo entloko.

Ingqondo kunye kwiCerebellum enxulumene afferent kunye efferent Imicu nkqubo luvo kunye onke amasebe, yaye ngabo kunye izihlunu kunye receptors amaninzi omzimba, kwakunye nenkqubo yawo luvo.

Eyona misebenzi iphambili ye kwiCerebellum ziquka: 1) ummiselo ezenzo mafutha; 2) ulawulo iinkqubo yawo. Ezi kwiCerebellum imisebenzi zasekwa ngo-eksperimenti usebenzisa ubuchule extirpation, ukutyabuka, ukurekhoda biopotentials imigqaliselo kwiCerebellum clinical.

KwiCerebellum iqulunqwa kakuhle iintaka kwaye kubalulekile ukuba ingqiqo yabo aphuhlileyo kakhulu eseleyo. Kweli xesha lokuqala emva kokususwa lentaka kwiCerebellum ayikwazi ukubhabha uhambe. Xa uzama ukususa unditsho apho, nentaka uwela ecaleni. Noko ke, kusenokungabi lula ukutya neziselo. Emva kwexesha elithile, imeko luyaphucuka nentaka unako, nangona kwaba ngenkankulu, ukuba eme, ukuhamba ukubhabha. Izifundo Scientific aye abonisa ukuba kwiCerebellum ibekwe amaziko elawula umsebenzi kwenkqubo yawo luvo.

iintaka Umzali ubuchopho (ubuchopho) ziphuhliswa kakuhle kwaye iquka iinxalenye ezimbini: i colliculus awongamileyo kunye nemilenze. Colliculus has a ngaphambili kunye isithinzi angasemva kunye luvo sensory nuclei kwakhiwa.

Eyona umsebenzi ubuchopho: 1. Inxalenye ngaphambili colliculus eliphezulu liziko lokuqala ezibonwayo. Apha kukho uhlalutyo yokuqala nokushukunyiswa ukukhanya. Ekubeni indlela yenziwa okuyona ukuya zovuselelo ukukhanya nge kumaziko (ukujikeleza intloko kwicala isivuseleli ukukhanya). Kumaziko phambi colliculus ophezulu ilawula yindibanisela umfundi. 2. Inxalenye colliculus diff uthwala impendulo ekuqhelaniseni kwizinto ekuva (vula intloko isandi isivuseleli). 3. Le nigra substantia othatha inxaxheba ekumiseleni skeletal imisipha. Ukwalawula isenzo kukuginya kwaye ukuphefumla isingqisho. 4. ubuchopho, okanye mandithi avareji kobuchopho iziko engathethekiyo ingqondo ekulungiseni. ikhaliphe ekulungiseni zibizwa ngokuba ikhaliphe ukubuyisela kwindawo eqhelekileyo umzimba emva iintanda.

Ubuchopho izirhubuluzi, ngokungafaniyo ingqondo intaka ingqondo na ubuchopho ngokwaneleyo.

Obuphakathi iqulathe thalamus, kunye yobuchopho epithalamus. Diencephalon wenza imisebenzi ezininzi. 1. Le thalamus yi sokuqokelela leyo abaqokelela la kuzo zonke receptor komzimba (ezibonwayo, ezikhalayo, gustatory, nezihlwabisayo, ubushushu, iintlungu, proprioceptors) ayithumele ukuya zifaka lobuchopho. 2. Xa eziba le thalamus amaza afferent ziphantsi uhlalutyo lokuqala kwaye ehlaziya. 3. Kulo thalamus, iminqweno afferent baba ngokweemvakalelo. Kukho imvakalelo buhlungu, evakalelwa ezimnandi ezingemnandi. 4. thalamus olawula izihlunu ithoni iplastiki, apho iintaka ezinakho ukufumana ukugcina ezahlukahlukeneyo ibonakala. 5. epithalamus ngamaziko elawula umsebenzi lo analyzer ukuqgiba. 6. Amaziko hypothalamic lobulali elawula umfundi komlomo, uxinzelelo lwegazi, yokuphefumla, kwaye motor kunye nemisebenzi secretory le lokugaya. 7. Le ngxenye lobushushu emzimbeni silawula.
