Qhov sib txawv tseem ceeb ntawm cilia stereocilia thiab microvilli yog cilia yog cov plaub hau me me zoo li cov qauv tsim los ntawm microtubules thaum stereocilia yog cov pob ntawm cov plaub hau zoo li qhov projections muaj li ntawm actin filaments thiab microvilli yog folds ntawm cell membranes uas muaj li ntawm actin filaments.
Cilia, stereocilia thiab microvilli yuav tshwm sim zoo li cov qauv thaum pom los ntawm sab nraud. Tab sis lawv yog structurally thiab functionally txawv ntawm ib leeg. Lawv yog cov plaub hau zoo li cov qauv uas yog microscopic. Ntxiv mus, lawv yog cov protein fibers uas nthuav tawm sab nraud ntawm lub hlwb.
Cia yog dab tsi?
Cilia yog luv dua thiab me me zoo li cov plaub hau zoo li muaj nyob rau ntawm qee qhov ntawm tes. Feem ntau, cilia muaj qhov ntev ntev. Lawv yog tsim los ntawm cov hlab ntsha hu ua microtubules. Cilia feem ntau yog motile. Lawv qhia cov suab nrov, cheb cov lus kom txav cov khoom nyob rau hauv ib qho kev taw qhia mus rau lub epithelial nto. Muaj peb ntu ntawm cilium. Lawv yog lub cev basal, thaj chaw hloov pauv thiab axoneme. Lub cev basal yog lub hauv paus ntawm cilium.
Daim duab 01: Cilia
Tseem muaj qee yam uas tsis yog-motile cilia thiab. Motile cilia qhia 9+2 microtubule kev npaj thaum uas tsis yog-motile cilia muaj 9+0 kev npaj. Cilia kab lub epithelium ntawm peb txoj kev ua pa. Hauv cov pa ua pa, cilia cheb tawm cov hnoos qeev, plua plav, thiab av, pab peb ua pa yooj yim dua. Tsis tas li ntawd, cilia muaj nyob rau hauv kev ua me nyuam, tshwj xeeb tshaj yog nyob rau hauv cov txiv neej reproductive system.
Stereocilia yog dab tsi?
Stereocilia yog cov plaub hau zoo li cov plaub hau uas muaj li ntawm actin-based protein filaments. Qhov tseeb, lawv yog bundles ntawm cov plaub hau zoo li projections. Lawv ntev dua cilia. Tsis zoo li cilia, stereocilia tsis-motile. Zoo ib yam li microvilli, stereocilia yog absorptive.
Daim duab 02: Stereocilia
Muaj stereocilia hauv pob ntseg sab hauv hauv auditory thiab vestibular sensory cells. Nyob rau hauv muaj, stereocilia ua hauj lwm raws li sensory transducers. Tsis tas li ntawd, stereocilia muaj nyob rau hauv txiv neej txoj kev loj hlob. Nyob ntawd, stereocili pab txhawb kev nqus ntawm cov epididymis thiab ductus deferens.
Microvilli yog dab tsi?
Microvilli yog cov quav ntawm cov cell membrane ntawm qee lub hlwb, tshwj xeeb tshaj yog nyob rau hauv cov hlwb uas nqus thiab tso tawm. Lawv nthuav tawm sab nraud los ntawm qhov chaw ntawm lub cell. Zoo ib yam li cilia, lawv muaj plaub hau zoo li lub ntsej muag. Qhov tseeb, lawv yog cov protein fibers. Lawv muaj actin filaments.
Daim duab 03: Microvilli
Microvilli tshwj xeeb rau kev nqus thiab tso tawm. Yog li ntawd, lawv feem ntau muaj nyob rau hauv lub plab zom mov thiab ob lub raum. Peb cov hnyuv muaj ntau microvilli. Microvilli nce thaj tsam ntawm cov cell membrane rau kev nqus. Yog li ntawd, qhov ua tau zoo ntawm cov txheej txheem nqus tau zoo. Tsis zoo li cilia, microvilli tsis txav. Ntxiv mus, microvilli luv dua cilia.
Dab tsi zoo sib xws ntawm Cilia Stereocilia thiab Microvilli?
- Cilia, stereocilia thiab microvilli yog cov plaub hau zoo li pom hauv tib neeg lub cev.
- Lawv yog cov qauv microscopic uas muaj cov protein fibers.
- Lawv nthuav tawm sab nraud ntawm lub xovtooj.
Qhov txawv ntawm Cilia Stereocilia thiab Microvilli yog dab tsi?
Cilia yog cov plaub hau zoo li microtubule uas tsim los ntawm cov hlwb. Stereocilia yog cov pob ntawm actin-raws li filaments thaum microvilli yog folds ntawm cell membranes ntawm absorptive thiab secretory cells. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cilia stereocilia thiab microvilli. Cilia feem ntau yog motile thaum stereocilia thiab microvilli tsis-motile. Ntxiv mus, stereocilia thiab microvilli yog nqus tau thaum cilia tsis yog.
Cov duab hauv qab no qhia ntau qhov kev piav qhia ntawm qhov sib txawv ntawm cilia stereocilia thiab microvilli.
Summary – Cilia Stereocilia vs Microvilli
Cilia, stereocilia thiab microvilli yog peb hom plaub hau zoo li cov qauv siv tshuaj pom nyob hauv tib neeg lub cev. Cilia yog motile thaum stereocilia thiab microvilli tsis-motile. Ntxiv mus, stereocilia thiab microvilli yog nqus tau thaum cilia tsis yog. Cilia yog tsim los ntawm microtubules thaum stereocilia thiab microvilli yog tsim los ntawm actin filaments. Yog li, qhov no qhia txog qhov sib txawv ntawm cilia stereocilia thiab microvilli.
