Ushwankathelo

Ingqondo yenziwa ngaphezu kwewaka lesigidi semithambo-luvo. Amaqela athile abo, esebenza ekhonsathini, asinike amandla okuqiqa, ukuba neemvakalelo kunye nokuqonda umhlaba. Banika nathi amandla okukhumbula iziqwenga zolwazi.

Zintathu izinto eziphambili zobuchopho. I-cerebrum lelona candelo likhulu, linwenwela ngaphezulu kwentloko ukuya kwinqanaba lendlebe. I-cerebellum incinci kune-cerebrum kwaye iphantsi kwayo, ngasemva kweendlebe ngasemva kwentloko. Ingcambu yengqondo yeyona incinci kwaye iphantsi kwe-cerebellum, yehla iye ezantsi iphinde ibuyele entanyeni.

I-cerebral cortex yinxalenye engaphandle ye-cerebrum, ekwabizwa ngokuba yi "grey matter". Ivelisa ezona ngcinga zintsonkothileyo zengqondo kunye nokulawula ukuhamba komzimba. I-cerebrum yahlulwe yangamacala asekhohlo nasekunene, anxibelelana nabanye ngesiqu esibhityileyo semicu yentliziyo. Iigroves kunye nezibaya zonyusa indawo yomgangatho we-cerebrum, zisivumela ukuba sibe nenani elikhulu lezinto ezingwevu ngaphakathi kokhakhayi.

Icala lasekhohlo lobuchopho lilawula izihlunu kwicala lasekunene lomzimba kwaye ngokuchaseneyo. Apha, icala lasekhohlo lobuchopho liqaqanjisiwe ukubonisa ulawulo lwengalo yasekunene kunye nentshukumo yomlenze, kwaye icala lasekunene lobuchopho liqaqanjisiwe ukubonisa ulawulo lwengalo yasekhohlo kunye nentshukumo yomlenze.

Ukuhamba komzimba ngokuzithandela kulawulwa ngummandla we-lobe yangaphambili. I-lobe yangaphambili ikwalapho simisa khona iimpendulo zovakalelo kunye neenkcazo

Zimbini ii-lobes zeparietali, enye kwicala ngalinye lobuchopho. Ii-lobes zeparietali zibekwe ngasemva kwe-lobe yangaphambili ngasemva kwentloko nangaphezulu kweendlebe. Iziko lokungcamla libekwe kwi-parietal lobes.

Zonke izandi zenziwa kwi-lobe yexeshana. Zikwabalulekile ekufundeni, kwimemori nakwiimvakalelo. I-lobe ye-occipital ibekwe emva kwentloko ngasemva kwe-lobari ye-parietal kunye ne-temporal lobes.

I-occipital lobe ihlalutya ulwazi olubonakalayo oluvela kwi-retina kwaye emva koko isebenzise olo lwazi. Ukuba i-occipital lobe yonakele, umntu unokuba yimfama, nokuba amehlo akhe ayaqhubeka nokusebenza ngesiqhelo

I-cerebellum ibekwe emva kwentloko phantsi kwe-lobipipital kunye ne-lobes yexeshana. I-cerebellum yenza iinkqubo ezizenzekelayo ukuze senze intshukumo entsonkothileyo ngaphandle kokucinga.

Ingcambu yengqondo ibekwe phantsi kwe-lobes yokwexeshana kwaye yandiselwe ezantsi kwintambo yomqolo. Kubaluleke kakhulu ekusindeni kuba idibanisa ingqondo kunye nentambo yomgogodla. Inxalenye ephezulu yengqondo ibizwa ngokuba yi-midbrain. I-midbrain yinxalenye encinci yesikhondo sobuchopho esikumphezulu wengcambu yengqondo. Ngaphantsi nje kwe-midbrain kukho iipon, kwaye ngaphantsi kwepons yi-medulla. I-medulla yinxalenye yengqondo esondele kufutshane nentambo yomqolo. I-medulla, kunye nemisebenzi yayo ebalulekileyo, ilele nzulu ngaphakathi kwentloko, apho ikhuselwe kakuhle ekonzakaleni kwecandelo elingqindililiyo lokakayi. Xa silele okanye kungekho nto siyaziyo, ukubetha kwentliziyo yethu, ukuphefumla kunye noxinzelelo lwegazi ziyaqhubeka nokusebenza kuba zilawulwa yimedulla.

Kwaye oko kugqiba ukujonga ngokubanzi izinto zengqondo.

• Izifo zeBongo
• Izibilini zeBongo
• Ukonzakala kwengqondo ebuhlungu
