Isifundo esidala kwisebe le-orthodontic leYunivesithi yase-Edinburgh yesikolo samazinyo safumanisa ukuba ubude bolwimi obuphakathi kubantu abadala zii-intshi ezi-3.3 (8.5 iisentimitha) zamadoda kunye nee-intshi ezi-3.1 (7.9 cm) kwabasetyhini.

Umlinganiso wenziwe kwi-epiglottis, i-flap cartilage ngasemva kolwimi naphambi kwengqula, ukuya kwincam yolwimi.

Qhubeka ufunda ukuze ufunde ngakumbi ngolwimi, kubandakanya ukusebenza kwalo, ukuba lwenziwe ngantoni, olona lwimi lude lwakha lwabhalwa, kunye nokunye.

Umsebenzi wolwimi

Ulwimi lwakho lunendima ebalulekileyo kwimisebenzi emithathu ebalulekileyo:

• ukuthetha (ukwenza izandi zentetho)
• ukugwinya (ukutya okuqhubela phambili)
• ukuphefumla (ukugcina ukuvulwa komoya)

Lwenziwe ngantoni ulwimi lomntu?

Ulwimi lomntu lunolwakhiwo oluntsonkothileyo oluyivumela ukuba ihambe kwaye yenze imilo eyahlukeneyo ngendima yayo ekutyeni, ekuthetheni nasekuphefumleni.

Ulwimi ngokuyintloko luquka umsipha wamathambo phantsi kwesigqubuthelo senwebu yangaphakathi. Kodwa ulwimi aluyomisipha nje enye: Izihlunu ezisibhozo ezahlukeneyo zisebenza kunye kwi-matrix eguqukayo ngaphandle kwamathambo okanye amalungu.

Esi sakhiwo siyafana nesiqu sendlovu okanye i-octopus tentacle. Ibizwa ngokuba yi-muscular hydrostat. Izihlunu zolwimi kuphela kwezihlunu emzimbeni ezisebenza ngokuzimeleyo emathanjeni.

Ingaphakathi kunye nezihlunu zamathambo ezingaphandle

Ingaphakathi kunye nezihlunu zamathambo zangaphandle zenza ulwimi lwakho.

Imisipha yangaphakathi iphakathi kolwimi. Benza lula ukuginya nokuthetha ngokukuvumela ukuba utshintshe imilo kunye nobungakanani bolwimi lwakho kwaye ulincamathisele ngaphandle.

Izihlunu zangaphakathi zezi:

• ubude obude buphantsi
• longitudinal liphezulu
• ulwimi olunqamlezileyo
• nkqo ulwimi

Izihlunu ezingaphandle zivela ngaphandle kolwimi lwakho kwaye zifake kwizicubu ezinxibelelanayo ngaphakathi kolwimi lwakho. Ukusebenza kunye, bona:

• ukubeka ukutya okuhlafunwayo
• ukumilisela ukutya kubunzima obujikeleziweyo (bolus)
• beka ukutya kokuginya

Imisipha engaphandle yile:

• mylohyoid (iphakamisa ulwimi lwakho)
• hyoglossus (utsala ulwimi lwakho ezantsi nasemva)
• I-styloglossus (utsala ulwimi lwakho nasemva)
• genioglossus (utsala ulwimi lwakho phambili)

Olona lwimi lude lurekhodiweyo

NgokweRekhodi yeHlabathi ye-Guinness, olona lwimi lude lwakha lwashicilelwa lolukaNick Stoeberl waseCalifornia. Ziyi-3.97 intshi (10.1 cm) ubude, ilinganiswa ukusuka kwincam yolwimi olwandisiweyo ukuya embindini womlomo ophezulu.

Ngaba kuyinyani ukuba ulwimi sesona sihlunu sisebenza nzima emzimbeni?

NgokweThala leencwadi leCongress, ulwimi lusebenza nzima. Isebenza naxa ulele, utyhala amathe emqaleni wakho.

Isihloko sesona sihlunu sisebenza nzima emzimbeni, nangona kunjalo, siya entliziyweni yakho. Intliziyo ibetha ngaphezulu kwamawaka ezigidi ezi-3 ebomini bomntu, impompa ubuncinci be-2,500 yeelitha zegazi yonke imihla.

Zingaphi iincasa endinazo?

Uzalelwe malunga namawaka alishumi eencasa. Nje ukuba udlule kwiminyaka engama-50 ubudala, ungaqala ukuphulukana nezinye zazo.

Iiseli zokungcamla kwi-taste buds zakho ziphendula ubuncinci kwiimpawu ezisisiseko zokungcamla

• ityuwa
• iswiti
• umuncu
• Ikrakra
• umami (enomdla)

Ngaba ulwimi lwam lwahlukile kolunye ulwimi?

Ulwimi lwakho lunokuhluka njengeminwe yakho. Akukho zimbini zokuprinta ulwimi ezifanayo.Ngapha koko, uphononongo luka-2014 lwafumanisa ukuba kwaneelwimi zamawele afanayo azifani.

Icacisiwe ukuba ngenxa yokungaqhelekanga, ulwimi lwakho lusenokusetyenziselwa ukuqinisekiswa kwesazisi ngenye imini.

Uphononongo luqukumbele ukuba uphando olukhulu kufuneka lubekwe ekuchongeni onke amanqaku olwimi anokuba luncedo kwiinkqubo zokuqinisekiswa kwe-biometric kunye ne-forensics.

Ngaba iilwimi zinokubeka ubunzima?

Ngokwelwimi, amanqatha olwimi kunye nobunzima bolwimi bunokudityaniswa ngokuqinisekileyo ngamanqanaba okutyeba kakhulu.

Uphononongo lufumene ulungelelwaniso phakathi kwevolumu yolwimi kunye nokuqina kobuthongo bokuphefumla.

Ukuthatha

Zonke iilwimi zahlukile.

Ubude obude bolwimi bumalunga nee-intshi ezintathu. Inemisipha esibhozo kwaye inee-buds ezingama-10,000 zokungcamla.

Ulwimi lubalulekile ekuthetheni, ekuginyeni nasekuphefumleni. Imicimbi yezempilo yolwimi: Banokufumana amanqatha kwaye benze mandundu ukuphazamiseka kwendlela yokulala.
