Cov no hu ua papillae (hais: puh-PILL-ee), thiab feem ntau ntawm lawv muaj saj qab . Saj buds muaj cov plaub hau rhiab heev hu ua microvilli (hais: mye-kro-VILL-eye).
Ib yam li ntawd, tib neeg nug, hom papillae twg muaj qhov nyiam saj?
TASTE BUDS THIAB CELLS tus nplaig muaj 4 hom papillae , feem ntau hom , filiform, yog nyias thiab xaim zoo li tus thiab tsis ua muaj saj buds . Nyob rau ntawm dorsal, ciam teb pem hauv ntej ntawm tus nplaig yog cov duab puab papillae , fungiform, cov muaj saj buds nyob ze ntawm nruab nrab lossis hauv qhov tawg ntawm papillae.
Ib yam nkaus, foliate papillae saj li cas? Foliate Papillae . Cov foliate cov papillae muaj kev koom tes nyob rau hauv cov kev xav ntawm saj thiab muaj saj buds embedded nyob rau hauv lawv qhov chaw. Cov foliate papillae tau sib koom ua ob pawg nyob ntawm txhua sab ntawm tus nplaig, tsuas yog nyob rau pem hauv ntej ntawm V ntawm valate papillae.
dab tsi yog 3 hom saj buds?
Nyob rau saum nplaim tus nplaig tau tsa pob, hu ua papilla, uas muaj cov saj qab . Muaj peb hom ntawm papilla, raws li lawv cov tsos: valate, foliate, thiab fungiform. Structures Associated nrog Saj . Tus nplaig tau npog nrog papillae (a), uas muaj saj qab (b thiab c).
Puas yog qhov saj saj yog neuron?
Cov saj qab tau kos rau hauv epithelium ntawm tus nplaig thiab ua kev sib cuag nrog ib puag ncig sab nraud los ntawm a saj cov pore. Nyob rau hauv lawv qhov kawg lub saj receptor cells synapse, lossis txuas, nrog kev nkag siab zoo neurons , paj hlwb uas ua cov ntaub ntawv rau lub hlwb.
