Umsebenzi futhi indlela ulimi olwakheke ngayo

Ulimi lomuntu - kuyinto isitho kwemisipha ise ngalo ingaphakathi ngomlomo. takhi telulwimi inquma ngqo izakhiwo nemisebenzi emzimbeni. Lokhu umzimba kubaluleke kakhulu, njengoba kunikeza nekhono lokuqonda futhi ukuhlukanisa ukunambitheka, futhi unesibopho ke.

Isakhiwo solimi lwabantu

Ngakho, njengoba sekushiwo, ulimi - kuba isitho esikhulu kwemisipha. It liqukethe izingxenye ezintathu:

• impande olimi - ingxenye ukuthi unamathele ithambo hyoid kanye mandible.
• Umzimba - cishe wonke umzimba.
• Phezulu - engxenyeni kweselula olimi ebhekene phambili.

Umsuka yolimi phakathi molars futhi ezimboziwe nge okuthiwa mucosa palato-lingual lwaleli. Okulandelayo ingxenye enkulu yomzimba - emzimbeni. Ihlala phakathi amagatsha umhlathi ongezansi. Ingxenye engenhla ulimi nozobamba ukuba isibhakabhaka nasemphinjeni, okuthiwa ngemuva - ihlukaniswe ibe inkatho okujulile sagittal. Engxenyeni engezansi imahhala kancane kuphela, eduze emphinjeni enamathiselwe imisipha. Ebusweni ohlangothini umzimba bukhomba ku amatomu, okuyinto kungabonwa yiwo wonke oqeda ulimi ngokumelene ulwanga.

Kumi esiqongweni sezindawo umzimba embozwe ulwelwesi lwamafinyila, equkethe papillae lingual. Kuyathakazelisa ukuthi lapho yinhlanganisela zokwakheka lymph ukuthi zakha okuthiwa idlala lingual emnyangweni ulimi labaqaphi elingemuva.

I mucosa nezilimi ungqimba submucous kuqukethwe nenqwaba nezindlala salivary ezincane, okuyinto kuhlelwe imfihlo ogxile okuxubile.

nezimiso zolimi futhi uchaza umsebenzi walo.

• Ulimi ehilelekile machining ukudla - ke Ihlangana ukudla amathe futhi ehilelekile kumiswa webele ukudla.
• Ulimi inikeza ekuqaleni isenzo ukugwinya - ngokushesha nje ukudla uthola ukuba impande webele, ayeke nokugwinya reflex engasakwazi.
• Ngenxa receptor mechanical ukunambitheka kuba umzimba touch futhi ukunambitheka.
• Ulimi ehilelekile kumiswa isho, inkulumo yomuntu.
• Njengoba yayo ulwelwesi lwamafinyila libhekene permeability high, ikuvumela ukuba ngokushesha yomqondo nutrients, kuhlanganise nezidakamizwa.

lwemtimba papillae ebucayi

Ngokuhamba evele ngamaqembu ebucayi papillae. Banquma ukwaba lezi zinhlobo ezilandelayo:

• Tapered futhi filiform papillae kukhona receptor mechanical ethintekayo.
• Mushroom emise wahlela emaphethelweni nezilimi eduze phezulu yayo. Iqukethe ukunambitheka efihlekile.
• papillae wokuxovela emise kukhona amayunithi ngobukhulu, ezithinta ukunambitheka efihlekile. Inombolo yabo ziyahlukahluka kusuka izingcezu eziyisikhombisa kuya kwabayishumi nambili. Basuke ahlelwe ngendlela V Roman inani
• papillae Foliate kukhona okungcono imiphetho olimi futhi ukwenza njenge isithokela receptor.

Kusukela okuzwa ukudla ukunweba eziyimpumelelo emsipheni ayingxenye le analyzer ukunambitheka kanye wenziwa ezindaweni ezithintekile we- cortex cerebral.

Isakhiwo ulimi futhi izinzwa zokunambitha

Nambithani ama ibekwe hhayi kuphela phezu olimi. Lemisebenti ingaphindze kubonakala phezu ezingemuva epiglottic uqwanga futhi acinene ebusweni Sky. Manje ngoba sewuyazi ukuthi izimiso eziyisisekelo takhi telulwimi, ngakho-ke kuhle ukucabangela indlela ukunambitheka ibonwa.

Wamukele ukuhlukanisa okuthandwa ezine eziyisisekelo: okunosawoti, waba nenhliziyo ebuhlungu, amnandi futhi omuncu. Ngayinye yalezi ethize iqembu ukunambitheka receptor ezahlukene.

Salty ukunambitheka ejwayelekile yenethiwekhi i-sodium chloride, okuyinto basabela papillae, elise at emaphethelweni ulimi ngokufanele nangesidingo phambi ingxenye yayo. Kodwa ukunambitheka omuncu ibonwa ngaseceleni emaphethelweni ngemuva umzimba. Lokhu ukunambitheka incike pH ketshezi.

bumnandi ukuzihlanganisa unoshukela ekudleni, nakuba ukusabela ngaleyo ndlela eba kanye glycerin, futhi abanye amaprotheni amino acid. Umtshina okuthiwa G-amaprotheni. Nambithani ezenza umuntu ezwe amnandi, zitholakala ichopho ngolimi lwakho. ukunambitheka ababayo is ziqondakala efanayo G-amaprotheni. Zibekele receptor esisogwini impande olimi.
