Tsis tas li ntawd, tsib hom receptors yog dab tsi?

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
