Kev zais cia ntawm qaub yog hauv qab tswj ntawm autonomic lub paj hlwb, uas tswj ob lub ntim thiab hom ntawm qaub ncaug secreted . Parasympathetic stimulation los ntawm lub hlwb, raws li tau zoo pom los ntawm Ivan Pavlov, ua rau kom zoo heev. zais cia , nrog rau nce ntshav ntws mus rau qaub ncaug qog.
Raws li, cov paj hlwb twg yog lub luag haujlwm rau cov kua qaub?
Autonomic Tswj Saliva yog tsim thiab zais los ntawm cov qog qaub ncaug ntawm lub cev. Cov qog no nyob rau hauv kev tswj ntawm lub autonomic paj hlwb , muaj xws li sympathetic thiab parasympathetic paj fibers.
Ib tug kuj tseem nug, qhov twg ntawm lub hlwb tswj cov qaub ncaug hauv qhov ncauj? Cov ib feem ntawm lub hlwb lub luag haujlwm rau qhov no qaub ncaug reflex yog medulla oblongata uas tswj ntau yam haujlwm los ntawm txham mus rau ntuav. Thaum tau txais cov kev txhawb siab no, medulla oblongata xa cov neurotransmitters mus rau cov qog kom tsim tau qaub.
Hauv txoj kev no, dab tsi ua rau cov qog ua kua qaub rau zais zis?
Cov zais cia ntawm qaub ( salivation ) yog kho los ntawm parasympathetic kev txhawb zog ; acetylcholine yog lub zog ua haujlwm neurotransmitter thiab khi rau muscarinic receptors hauv qog , ua rau nce ntxiv salivation.
Puas tuaj yeem tswj tau qhov qaub ncaug?
Qhov ncauj qhov ncauj yog nyob ntawm qaub thiab nws cov ntsiab lus ntawm cov protein. Reflex salivary ntws tshwm sim ntawm qhov qis 'so' tus nqi thiab rau lub sijhawm luv luv ntawm ib hnub ntau kev saj los yog zom stimuli evoke mus txog kaum npaug nce hauv salivation. Qhov zais ntawm qaub ncaug kua thiab proteins yog tswj los ntawm autonomic paj hlwb.
Pom zoo:
Cov qog twg ua cov qaub ncaug ntau tshaj?
Parotid qog
Yuav ua li cas yog tias cov qaub ncaug tsis zais los ntawm cov qog ua kua?
Cov qaub ncaug tseem ua rau lub qhov ncauj huv thiab noj qab nyob zoo vim nws muaj cov tshuaj tiv thaiv kab mob tua cov kab mob. Yog tias cov qog nqaij hlav hauv lub cev puas los yog tsis tsim cov kua qaub txaus nws tuaj yeem cuam tshuam rau saj, ua zom thiab nqos tau nyuaj dua, thiab ua rau muaj kev pheej hmoo rau kab noj hniav, poob hniav, thiab kis kab mob hauv lub qhov ncauj
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
Cov qog twg tsim cov qaub ncaug?
Loj Salivary Glands. Cov qog qaub ncaug loj yog cov qog loj thiab tseem ceeb tshaj plaws. Lawv tsim cov qaub ncaug feem ntau ntawm koj lub qhov ncauj. Muaj peb khub ntawm cov qog qaub ncaug loj: cov qog parotid, cov qog submandibular, thiab cov qog nqaij hlav sublingual
