Loj Salivary Glands. Cov qog qaub ncaug loj yog cov qog qaub ncaug loj tshaj plaws thiab tseem ceeb tshaj plaws. Lawv tsim cov qaub ncaug feem ntau ntawm koj lub qhov ncauj. Muaj peb khub ntawm cov qog ua kua qaub loj: tus parotid qog , cov qog submandibular, thiab cov qog sublingual.
Tom qab ntawd, cov qog twg tsim cov qaub ncaug ntau tshaj?
Cov qog salivary loj (parotid, submandibular , thiab sublingual) tsim feem ntau ntawm salivary secretion (txog 80%). Lwm cov qaub ncaug yog tsim los ntawm cov qog me me uas tawg thoob plaws hauv lub qhov ncauj.
Ib tug kuj yuav nug, hom qaub ncaug yog tsim los ntawm cov qog parotid? Cov qog ua kua qaub me me rau ntawm nplaig zais cov amylase. Lub qog parotid ua cov qaub ncaug dawb huv. Lwm cov qog qaub ncaug loj tsim cov kua qaub (serous thiab mucus) qaub ncaug. Lwm hom kua dej ua kua yog zais los ntawm ob txheej txheej ua kua uas ua kab hauv lub cev kab noj hniav.
Ib sab ntawm qhov no, ua li cas cov qog qaub ncaug tsim cov qaub ncaug?
Kua qaub yog ua nyob rau hauv thiab secreted los ntawm salivary qog . Basic secretory units ntawm salivary qog pawg ntawm cov hlwb hu ua acini. Cov hlwb no zais Cov kua dej uas muaj dej, electrolytes, mucus thiab enzymes, tag nrho cov uas ntws tawm ntawm lub acinus mus rau sau ducts.
Dab tsi yog 3 cov qog ua kua qaub thiab lawv ua haujlwm li cas?
Nws kuj tseem pab txhawm rau zom cov carbohydrates (nrog qaub ncaug amylase, yav tas los hu ua ptyalin) thiab ua kom cov khoom noj nkag los ntawm lub oro-pharynx mus rau txoj hlab pas mus rau lub plab. Muaj yog peb cov khub tseem ceeb ntawm salivary qog : ua parotid , submandibular thiab sublingual qog.

Dab tsi ua rau cov qog qaub ncaug zais?
Cov kua dej muaj cov enzyme amylase uas ua rau zom cov carbohydrates. Cov qog ua kua qaub me me ntawm tus nplaig zais cov amylase. Cov kab mob parotid tsim cov kua qaub ntshiab. Lwm qhov loj salivaryglands tsim sib xyaw (serous thiab mucus) qaub ncaug
Dab tsi yog qhov kev txiav txim ntawm cov kua qaub rau cov enzyme hauv qaub ncaug?
Carbohydrates tau tawg thoob plaws hauv lub plab. Salivary amylase yog ib qho enzyme hauv lub qhov ncauj uas pib zom cov carbohydrates hauv daim ntawv ntawm cov hmoov txhuv nplej los ntawm kev cuam tshuam cov hydrolysis ntawm polysaccharides rau hauv disaccharides. Txawm li cas los xij, qhov chaw tseem ceeb rau kev zom zaub mov carbohydrate yog cov hnyuv me
Pom cov qog qaub ncaug nyob qhov twg?
Koj muaj peb khub ntawm cov qog ua kua qaub nyob hauv qab thiab tom qab koj lub puab tsaig - parotid, sublingual thiab submandibular. Ntau lwm cov qog qaub ncaug me me nyob hauv koj daim di ncauj, hauv koj lub puab tsaig, thiab thoob plaws koj lub qhov ncauj thiab caj pas
