Umsebenzi kunye nesakhiwo ulwimi

Ulwimi wesintu - ilungu dystrophy ibekwe em- ngomlomo. isakhiwo ulwimi umisela ngqo iimpawu kunye nemisebenzi umzimba. Le umzimba kubaluleke kakhulu, njengoko inika amandla wokubona ukwahlula incasa, kwaye linoxanduva kuyo.

Ubume ulwimi lwabantu

Ngoko ke, njengokuba sele kukhankanyiwe, ulwimi - yinto ilungu enkulu dystrophy. It iqulathe ezintathu:

• Ingcambu ulwimi - inxalenye eqhotyoshelwe kule ithambo hyoid kunye mandible.
• Umzimba - uninzi umzimba.
• Umphezulu - inkoliso yemobile ulwimi zijonge phambili.

Root kolwimi phakathi imihlathi kunye egqubuthele kunye palato zeelwimi ezininzi ekuthiwa-isifo arch. Okulandelayo le nxalenye inkulu lomzimba - umzimba. Kuxhomekeke phakathi kwamasebe kwemihlathi asezantsi. Inxalenye nakumphezulu iilwimi buso esibhakabhakeni kunye umqala, ebizwa ngasemva - yahlulahlulwe yaba kukho umsantsa enzulu sagittal. Inxalenye olusezantsi free kancinci nje, njengokuba kufutshane umqala iqhotyoshelwe izihlunu. Umphezulu icala lomzimba idibane umkhala, leyo sibonwe baphakamise ulwimi nxamnye nenkalakahla.

On top of umzimba wambu inwebu yangaphakathi, leyo iqulathe papillae zeelwimi. Okubangel 'umdla kukuba kukho Sisihloko kwiziseko lymphoid eyenza ekuthiwa-idlala zeelwimi kwisebe ngolwimi angasemva.

Le isifo Ulwimi kunye maleko submucous luqulathwe ubunzima kwamadlala ezincinane amathe, nto leyo kuhlelwe imfihlelo ubukhulu becala mixed.

isakhiwo ulwimi acacise ukusebenza kwayo.

• Ulwimi inxaxheba machining ukutya - oku ixutywa ukutya kunye ematheni, kwaye inxaxheba ekubunjweni ukutya webele.
• Ulwimi inika ekuqaleni kwesenzo ligwinya - kamsinya nje ukutya ufumana ka ku kuso aka nencum, ayeke yokuginya reflex akusekho kunokwenzeka.
• Ngenxa receptors koomatshini kunye isongo ke umzimba kwebala kunye nemvakalo.
• Ulwimi libandakanyeka ekubunjweni uliciko, intetho yabantu.
• Ekubeni zayo inwebu yangaphakathi luphawulwa permeability aphezulu, it ikuvumela ukuba ukwazi ukumunca ngokukhawuleza ezinye izondlo, kuquka iziyobisi.

isakhiwo Language papillae onovakalelo

Ukutyhubela iindawo amaqela ezibuthathaka papillae. Isigqibo sokwabela ezi ndidi zilandelayo:

• Tapered kunye filiform papillae zizinto receptors koomatshini, nezihlwabisayo.
• Mushroom-emile wacwangcisa phezu kungqameko kolwimi kufutshane encopho yayo. Iqulethe azosala.
• papillae nomkhombe ezibusazinge iiyunithi inkulu, okuye azosala. Inani labo ingahluka kumaqhekeza ezisixhenxe ukuya kwezilishumi elinesibini. Bona amalungiselelo ngokohlobo V. waseRoma yesi
• papillae Foliate ke kukhethwa yaxakathwa ulwimi kwaye kwenza njengoko flavoring receptor.

Ukusuka ukunambitha Amaqhina ukwandisa kwalapho eziyinxalenye le analyzer incasa kunye oluqhutywa kumaziko ezahlukahlukeneyo neuron.

Ubume zolwimi kunye ukunambitha

Iibhalbhu Taste ezibekwe kungekuphela kumphezulu ulwimi. Kananjalo kubonakala phezu elingasemva epiglottic intlala kunye ngeempumlo umphezulu Sky. Ngoku uyazi imigaqo esisiseko lwesakhiwo solwimi, ngoko kubalulekile ukuqwalasela indlela incasa ibonwa.

Yamkela ukwahlula ezithandwa ezine ezisisiseko: ezinetyuwa, kukrakra, amnandi kunye ezimuncu. Nganye kwezi receptors ezithile iqela incasa ezahlukeneyo.

Ezinetyuwa yenethiwekhi standard incasa sodium chloride, leyo kusabela papillae, sise emiphethweni ulwimi kunye inxalenye ngaphambili. Kodwa incasa emuncu ziqondeka imiphetho ecaleni emva umzimba. Le ukunambitheka kuxhomekeke pH ukwimo.

incasa Sweet ukunxulumana ubukho eswekile ekutyeni, nangona ukusabela ngaleyo iphuhlise kwaye glycerin, yaye ezinye iiprothini kunye acid. Le kakutsha yinto ebizwa ngokuba yi-G-iiprothini. ezenza Ngcamlani esabelayo emnandi, akhiwe esithinzini ulwimi lwakho. incasa ekrakra kubonwa phindwe G-iiprothini. Cwangcisa of ezenza akhiwe kwi ingcambu kolwimi.
