Vocal cords qhib thiab kaw Vocal cords qhib thaum koj ua pa ces kaw los tsim suabthaum vibrating ua ke. Koj cov hlab ntsha yog ob txoj hlua hloov pauv ntawm cov leeg nqaij uas zaum ntawm qhov nkag mus rau hauv cov hlab cua (trachea). Thaum koj hais lus, cov pab pawg tuaj ua ke thiab vibrate ua suab.
Dab tsi ua rau lub suab qhib?
Koj lub suab qhib thaum koj ua pa thiab kaw nruj thaum koj nqosThaum koj hais lossis hu nkauj, koj lub suab kaw thiab koj lub ntsws xa cua los ntawm lawv, ua rau lawv vibrate thiab ua suab. Cov suab nkauj ua lub luag haujlwm tseem ceeb hauv kev pab peb tham, ua pa thiab nqos.
Dab tsi ua rau cov kab hluav taws xob pib qhib lossis kaw?
Cov folds vibrate thaum lawv kaw los thaiv cov cua ntws los ntawm glottis, qhov chaw nruab nrab ntawm cov quav: lawv raug yuam qhib los ntawm nce cua siab hauv lub ntsws, thiab kaw dua li huab cua rushes dhau lub folds, txo lub siab (Bernoulli txoj cai).
Cov kab hluav taws xob puas qhib tau?
Thaum koj ua pa, koj lub suab folds sib nrug thiab thaum koj nqos, lawv yog nruj kaw. Thaum koj siv koj lub suab, txawm li cas los xij, huab cua los ntawm lub ntsws ua rau koj lub suab folds kom vibrate ntawm qhov qhib thiab kaw.
Lub suab kaw thaum twg?
Vocal cord dysfunction (VCD) yog thaum koj lub suab cords (vocal folds) kaw thaum lawv yuav tsum qhib. Qhib lawv yog sab nraud ntawm koj tswj thiab, vim li ntawd, koj yuav muaj teeb meem ua pa. VCD tseem hu ua inducible laryngeal obstruction, paradoxical suab qaum zog (PVFM) thiab laryngeal dysfunction.
