Lub suab "tseeb" - yog ua los ntawm tsib txheej:
- epithelium - qhov chaw " tawv nqaij "ntawm cov lub suab nrov , uas yog txuas ntxiv nrog sab hauv ntawm lub qhov ncauj, pharynx thiab nrog lub trachea hauv qab no lub suab nrov .
- lamina propria cov - peb txheej txheej, txhua qhov sib txawv.
Tsis tas li ntawd, dab tsi yog qhov tob tshaj plaws ntawm lub suab folds?
Hauv qab no yog txheej txheej txheej ntawm lamina propria cov , gel zoo li txheej, uas tso cai rau lub suab fold kom vibrate thiab tsim suab. Lub suab thiab cov leeg nqaij thyroarytenoid ua qhov tob tshaj plaws.
Ib tug kuj yuav nug, yog lub suab folds leeg? Cov kab lus yog ob txoj hlua elastic nqaij ntaub so ntswg. Lawv nyob ib sab ntawm sab hauv suab lub thawv (larynx) cia li saum lub qhov cua (trachea). Zoo li lwm cov ntaub so ntswg hauv lub cev, kab lus tuaj yeem strained thiab puas. Cov kab suab kuj tseem raug tus kab mob, qog thiab raug mob.
Ib yam nkaus, hom ntaub so ntswg twg ua rau lub suab nrov?
Lub suab folds yog tsim los ntawm peb txheej loj los ntawm qhov tob mus rau sab saum toj:
- Lub Vocalis Muscle (labeled saum toj no raws li lub muscularis)
- Lub Lamina Propria (tiag tiag 3 txheej: sib sib zog nqus, nruab nrab, thiab sab saum toj)
- Lub epithelium los yog epithelial ntaub so ntswg.
Dab tsi yog qhov txawv ntawm lub suab folds thiab vestibular folds?
Cov vestibular quav , los yog dag kab lus , yog tsim los ntawm superior txheej ntawm infolded membrane; cov suab folds , los yog qhov tseeb kab lus , yog tsim los ntawm inferior txheej ntawm infolded membrane. Lub laryngeal ventricles txuas ntxiv tom qab thiab nyob nruab nrab cov lub vestibular thiab suab nrov.
