Nociceptors nthuav tawm khoom tshwj xeeb hluav taws xob uas teeb lawv sib nrug los ntawm qhov pib qis mechanoreceptors, uas nws lub cev ntawm tes kuj tseem nyob hauv kev hnov mob ganglia.
hom receptor yog Nociceptor?
Nociceptors yog sensory receptors uas ntes cov cim los ntawm cov ntaub so ntswg puas lossis kev hem thawj ntawm kev puas tsuaj thiab tsis ncaj qha rau cov tshuaj tso tawm los ntawm cov ntaub so ntswg puas. Nociceptors tsis pub dawb (liab liab qab) cov paj hlwb pom nyob rau hauv daim tawv nqaij (Daim duab 6.2), cov leeg, pob qij txha, pob txha thiab viscera.
Puas yog nociceptors chemoreceptors?
Mechanically insensitive C-fibers (C-MIAs) yog tsis teb rau cov neeg kho tshuab stimuli los yog muaj cov neeg kho tshuab siab heev. Cov afferents teb rau cov cua sov thiab ntau yam tshuaj lom neeg stimuli (piv txwv li, capsaicin, histamine) thiab feem ntau suav hais tias yog chemoreceptors.
Peb hom nociceptors yog dab tsi?
Hauv luv luv, muaj peb yam tseem ceeb ntawm nociceptors nyob rau hauv daim tawv nqaij: Aδ mechanosensitive nociceptors, Aδ mechanothermal nociceptors, thiab polymodal nociceptors, tom kawg yog tshwj xeeb nrog C fibers.
Puas yog cov nociceptors ib feem ntawm lub paj hlwb peripheral?
Tshwj xeeb peripheral sensory neurons hu ua nociceptors ceeb toom peb kom muaj peev xwm ua rau muaj kev puas tsuaj ntawm daim tawv nqaij los ntawm kev kuaj pom qhov kub thiab txias thiab cov tshuaj lom neeg raug mob, thiab hloov cov nostimuli mus rau qhov ntev-ntev hluav taws xob teeb liab uas tau xa mus rau cov chaw siab dua hauv lub hlwb.
