Larynx. Larynx yog kab los ntawm ciliated pseudostratified columnar epithelium tshwj tsis yog suab suab (kab los ntawm stratified squamous epithelium). Lub phab ntsa ntawm lub larynx tau txhawb nqa los ntawm cov nqaij mos. Cov pob txha loj (cartilago thyroidea, cartilago cricoidea) thiab ib feem ntawm pob txha mos arytenoidea yog tsim los ntawm cov pob txha hyaline.
Hauv qhov no, hom pob txha mos twg nyob hauv lub ntsws?
Cricoid pob txha mos : Ring ib hyaline pob txha mos uas tsim cov phab ntsa tsis zoo ntawm lub suab nrov . Nws yog txuas rau sab saum toj ntawm lub ntsws. Qhov nruab nrab cricothyroid ligament txuas rau cricoid pob txha mos mus rau cov thyroid pob txha mos . Epiglottis: Ib qho loj, zoo li rab diav zoo li daim pob txha mos.
Ib yam nkaus, peb lub luag haujlwm ntawm cov pos hniav yog dab tsi? Cov lub suab nrov ua hauj lwm peb tseem ceeb kev ua haujlwm hauv tib neeg.
