Cov txais tuaj ntau hom, tab sis lawv tuaj yeem muab faib ua ob pawg: intracellular cov receptors , yog pom sab hauv ntawm tes (hauv cytoplasm lossis nucleus), thiab ntawm tes nto cov receptors , yog pom nyob rau hauv lub plasma membrane.

Ib yam li ntawd, cov receptors nyob qhov twg?

Sensors receptors nyob nyob rau hauv lub dermis los yog epidermis ntawm daim tawv nqaij yog hu ua cutaneous cov receptors . Cov no muaj xws li nociceptors thiab thermoreceptors. Mechanoreceptors, ntawm qhov tod tes, yog nyob hauv cov leeg spindles, ua rau lawv pom cov leeg ncab.

Tom qab ntawd, lo lus nug yog, dab tsi yog 5 hom receptors? Cov ntsiab lus hauv txheej no (5)

chemoreceptors. txhawb los ntawm kev hloov pauv tshuaj lom neeg cov tshuaj.
mob receptors txhawb los ntawm kev puas tsuaj ntawm cov nqaij.
cov thermoreceptors. txhawb los ntawm kev hloov pauv ntawm qhov kub thiab txias.
cov kws kho tsheb. txhawb los ntawm kev hloov pauv siab lossis txav mus los.
photoreceptors. stimulated los ntawm lub teeb zog.

Kuj nug, 5 hom kev hnov qab neeg hnov thiab lawv nyob qhov twg?

Tsib qhov yooj yim hnov qab tus neeg txais qhov kawg muaj nyob hauv tib neeg lub cev: cov thermoreceptors kuaj pom qhov hloov pauv ntawm qhov kub thiab txias; cov kws kho tsheb teb rau lub cev deformation; nociceptors teb rau qhov mob, photoreceptors / electromagnetic receptors yog qhov muag receptors ntawm retina; chemoreceptors ntes hnov tsw, saj, sab hauv

Cov receptor cells ua haujlwm li cas?

Cell receptors ua haujlwm zoo ib yam rau cov neeg ncaws pob: Lawv tau txais cov cim thiab pib ua lus teb. Hauv biology, cov receptors yog cov proteins lossis glycoproteins uas tau txais cov cim qhia los ntawm kev khi rau cov cim taw qhia, feem ntau hu ua thawj cov tub txib lossis ligands, uas xa cov teeb liab tshwj xeeb rau tom ntej.
