Qhov sib txawv tseem ceeb ntawm kev cog lus thiab constriction yog qhov contraction yog txo qhov loj me los yog luv ntawm cov leeg, thaum constriction yog ua kom nruj, nqaim los yog kaw.

Kev sib cog lus thiab constriction yog ob hom txheej txheem uas tshwm sim hauv cov leeg. Contraction siv qhov chaw hauv cov leeg pob txha. Constriction tshwm sim nyob rau hauv cov leeg du. Ob qho tib si yog cov txheej txheem tsis yeem, tab sis kev cog lus yog qee zaum yeem. Contraction yog tshwm sim los ntawm qhov nro nyob rau hauv lub cev nqaij daim tawv nqaij fibers. Constriction yog tshwm sim los ntawm lub siab tshwm sim los ntawm cov nqaij ntshiv nyob rau hauv lub cev nyob rau hauv lub cev.

Kev cog lus yog dab tsi?

Kev cog lus yog tus txheej txheem ntawm kev ua kom ntev lossis txo qhov loj. Nws kuj yog cov txheej txheem ntawm kev ua me me los yog cov duab. Cov leeg nqaij contraction tshwm sim nrog kev ua kom muaj zog-tsim qhov chaw hauv cov leeg pob txha. Nws yog nyob ntawm ob yam sib txawv. Lawv yog qhov ntev thiab nro. Muaj ob hom leeg nqaij contractions: isometric thiab isotonic contractions.

Qhov txawv ntawm Contraction thiab Constriction

Daim duab 01: Hom Kev Cog Lus

Isometric nqaij contraction tshwm sim thaum lub sij hawm ntev ntawm cov nqaij ntshiv nyob twj ywm tib yam thaum lub nro hloov thaum lub sij hawm contraction. Isotonic nqaij contraction tshwm sim thaum cov leeg nqaij tensions tseem zoo ib yam thaum lub sij hawm contraction. Tab sis, nyob rau hauv no contraction, qhov ntev ntawm cov nqaij fibers hloov. Yog hais tias qhov ntev ntawm cov nqaij fibers shortens, nws yog concentric contraction. Yog hais tias qhov ntev ntawm cov nqaij fibers lengthens, nws yog ib tug eccentric contraction. Yog li ntawd, cov leeg nqaij contractions tsis tsuas yog luv luv ntawm cov nqaij fibers nrog cov leeg nro. Kev cog lus tshwm sim nrog thiab tsis muaj ib tus neeg paub. Yog li, nws yog induced thiab autonomic.

Kev txwv yog dab tsi?

Kev nruj yog txheej txheem ntawm kev nruj lossis nqaim kom ua rau muaj kev cuam tshuam. Qhov no tshwm sim thaum cov ntaub ntawv hla dhau. Constriction nyob rau hauv tib neeg lub cev physiology yog kaw los yog nqaim ntawm txoj kev mus nres los yog txwv tsis pub dhau ntawm cov ntaub ntawv. Cov txheej txheem no tshwm sim yam tsis muaj kev paub txog. Yog li ntawd, nws yog tus txheej txheem autonomic.

Kev tswj hwm lossis tswj kev dhau ntawm cov kua lossis cov khoom hauv lub cev. Constriction feem ntau tshwm sim hauv cov leeg du. Cov nqaij ntshiv yog pom nyob rau hauv lub cev ntawm tib neeg lub cev. Lawv muaj nyob rau hauv lub cev xws li lub qhov muag, plab, pharynx, hnyuv, zais zis, bronchi thiab ureter. Lawv kuj muaj nyob hauv lwm cov qauv xws li cov leeg nqaij sphincters thiab cov hlab ntsha. Constriction nyob rau hauv lub nruab nrog cev thiab lwm yam lug siv qhov chaw thaum cov nqaij mos cog lus.

Daim duab 02: Bronchoconstriction

Muaj ntau hom kev txwv, suav nrog vasoconstriction, pharyngoesophageal constriction thiab bronchoconstriction. Vasoconstriction yog constriction ntawm cov hlab ntsha los tswj cov ntshav ntws. Pharyngoesophageal constriction yog constriction nyob rau hauv lub kwj dej ntawm alimentary ntawm qhov sib txuas ntawm lub pharynx thiab txoj hlab pas los tswj kev dhau ntawm bolus tom qab nqos. Bronchoconstriction yog constriction ntawm lub bronchus thaum huab cua dhau los. Qhov no ua rau hnoos thiab hawb pob vim tias txoj hlab pas cuam tshuam vim kev txwv.

Dab tsi yog qhov zoo sib xws ntawm Contraction thiab Constriction?

  • Kev cog lus thiab constriction tshwm sim hauv cov leeg.
  • Ob leeg muaj qhov ua haujlwm tsis txaus ntseeg.

Qhov txawv ntawm Kev Txhaum Cai thiab Kev Txhaum Cai yog dab tsi?

Contraction yog tus txheej txheem ntawm shortening los yog txo qhov loj, whereas constriction yog txheej txheem ntawm nqaim los yog zawm. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev cog lus thiab constriction. Ntxiv mus, contraction feem ntau tshwm sim nyob rau hauv skeletal nqaij fibers, thaum constriction feem ntau tshwm sim nyob rau hauv cov leeg du. Yog li, qhov no yog lwm qhov sib txawv ntawm qhov contraction thiab constriction.

Tsis tas li ntawd, kev cog lus ua rau cov leeg ua kom muaj zog. Txawm li cas los xij, constriction tiv thaiv lossis tswj kev txav ntawm cov kua thiab cov khoom hauv lub cev. Tsis tas li ntawd, lub constriction tshwm sim nyob rau hauv ib tug passageway. Ntxiv nrog rau qhov sib txawv no, kev sib cog lus yog ib qho kev yeem los yog kev tsis txaus siab thaum lub sij hawm constriction yog ib txoj kev tsis yeem.

Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev cog lus thiab constriction nyob rau hauv daim ntawv tabular.

Summary – Contraction vs Constriction

Kev cog lus yog cov txheej txheem ntawm qhov luv ntawm qhov ntev lossis txo qhov loj. Cov leeg nqaij feem ntau tshwm sim nrog kev ua kom cov leeg nqaij pob txha. Muaj ob hom isometric contraction thiab isotonic contraction. Kev cog lus yog ob leeg yeem thiab tsis yeem. Constriction yog txheej txheem ntawm zawm lossis nqaim kom ua rau muaj kev cuam tshuam. Nws yog ib qho txheej txheem tsis yeem. Qhov no tswj lossis tiv thaiv kev dhau ntawm cov khoom thiab cov kua dej hauv txoj hauv kev hauv lub cev. Constriction feem ntau yog cov nqaij du. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm kev cog lus thiab constriction.
