Qhov sib txawv tseem ceeb ntawm basilar thiab tectorial membrane yog basilar membrane yog cov membrane uas tsim hauv pem teb ntawm cochlear duct, uas cov cochlear plaub hau hlwb pw, thaum tectorial membrane yog daim ntawv fibrous overlying apical nto ntawm cov plaub hau cochlear.
Cochlea yog ib qho qauv coiled pom nyob rau hauv pob ntseg sab hauv. Nws yog tus qauv tseem ceeb tshaj plaws nyob rau hauv txoj kev auditory. Nws amplifies suab nthwv dej thiab hloov lawv mus rau hauv neural signals. Structurely, nws yog ib tug kauv-zoo li tus pob txha, uas zoo li ib tug qwj plhaub. Nws muaj peb lub kwj dej (scala vestibuli, scala media, thiab scala tympani) uas khiav mus rau ib leeg. Ntxiv mus, nws yog ntim nrog ib tug kua. Muaj ob lub acellular membranes nyob rau hauv lub cochlea. Lawv yog cov basilar membrane thiab tectorial membrane. Auditory receptor hlwb pw ntawm lub basilar membrane thaum tectorial membrane lies hla lub auditory receptor hlwb los yog plaub hau hlwb. Ob leeg basilar membrane thiab tectorial membrane yog cov khoom ntawm lub cev ntawm Corti.
Basilar Membrane yog dab tsi?
Basialar membrane yog ib qho ntawm ob lub acellular membranes nyob rau hauv pob ntseg. Qhov no daim nyias nyias ua rau hauv pem teb ntawm cochlear duct. Basilar membrane faib cov spiraled cochlear rau hauv lub sab sauv thiab sab hauv. Lub auditory receptor hlwb los yog cov plaub hau hlwb pw embedded nyob rau hauv lub basilar membrane. Feem ntau, hauv tib neeg lub pob ntseg cochlea, muaj 3500 cov plaub hau sab hauv thiab 12,000 cov plaub hau sab nraud. Lawv raug teeb tsa raws cov basilar membrane raws li lawv cov lus teb zaus.
Daim duab 01: Basilar Membrane
Cov basilar daim nyias nyias yog qhov dav tshaj plaws thiab qhov nruj tshaj plaws ntawm lub apex ntawm cochlea thaum nws nqaim tshaj plaws thiab tawv tshaj plaws ntawm lub hauv paus. Qhov sib txawv ntawm basilar membrane vibrate nyob rau hauv teb rau suab. Thiab, qhov no yog tus yuam sij rau kev nkag siab ntawm cochlear muaj nuj nqi.
Tectorial Membrane yog dab tsi?
Cov tectorial membrane yog ib daim ntawv fibrous overlying apical nto ntawm cochlear plaub hau hlwb. Raws li txoj cai, nws yog cov qauv zoo li gel uas muaj 97% dej. Cov tswv yim ntawm cov plaub hau sab nrauv txuas ncaj qha rau daim nyias nyias.
Daim duab 02: Tectorial Membrane
Tsis tas li ntawd, lub tectorial daim nyias nyias yog nyob rau saum cov kauv limbus thiab cov khoom siv kauv ntawm Corti. Tsis tas li ntawd, nws txuas ntxiv raws qhov ntev ntev ntawm cochlea mus rau lub basilar membrane. Muaj peb thaj chaw ntawm tectorial membrane li limbal, nruab nrab thiab marginal zones. Lub limbal cheeb tsam yog thinnest thaum lub marginal cheeb tsam yog thickest. Tsis tas li ntawd, tectorial membrane yog qhov tseem ceeb rau kev noj qab haus huv auditory muaj nuj nqi hauv cov tsiaj nyeg. Nws cuam tshuam cov pob ntseg hauv pob ntseg los ntawm kev khaws cov calcium ions.
Dab tsi yog qhov zoo sib xws ntawm Basilar thiab Tectorial Membrane?
- Basilar thiab tectorial membranes yog ob lub cellular membranes nyob rau hauv lub cochlea ntawm puab pob ntseg.
- Lawv zwm rau lub cev ntawm Corti ntawm cochlea.
- Lawv dag sib luag.
- Basilar membrane txav txheeb ze rau tectorial membrane vim lub suab nthwv dej.
- Ob leeg, basilar thiab tectorial membrane yog qhov tseem ceeb rau kev noj qab haus huv ntawm tib neeg.
Qhov txawv ntawm Basilar thiab Tectorial Membrane yog dab tsi?
Cov basilar membrane yog ib daim nyias nyias ntawm cov plaub hau uas cov hlwb pw hauv thaum lub tectorial membrane yog ib daim ntawv fibrous overlying apical nto ntawm cochlear plaub hau hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm basilar thiab tectorial membrane. Tsis tas li ntawd, lwm qhov sib txawv ntawm basilar thiab tectorial membrane yog cov plaub hau hlwb los yog lub hlwb auditory receptors pw nyob rau hauv lub basilar membrane, thaum lub tectorial membrane nyob ntawm cov plaub hau hlwb.
Summary – Basilar vs Tectorial Membrane
Basilar thiab tectorial membrane yog ob lub cellular membranes nyob rau hauv cochlea ntawm lub pob ntseg. Lub auditory receptor hlwb pw embedded nyob rau hauv lub basilar membrane thaum lub tectorial membrane overlies lub apical nto ntawm cochlear plaub hau hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm basilar thiab tectorial membrane. Tsis tas li ntawd, lub basilar membrane tsim hauv pem teb ntawm cochlear duct. Suab nthwv dej ua rau cov basilar membrane txav mus rau tectorial membrane. Ob leeg, basilar thiab tectorial membrane yog ib qho tseem ceeb rau kev noj qab haus huv auditory muaj nuj nqi.
