Sensory receptors Sensory receptors Lub cell soma ntawm thawj qhov kev hnov mob neurons yog hluav taws xob txaus ntshai, thiab raug cuam tshuam los ntawm kev ua tau zoo thaum lawv dhau los ntawm cov hlab ntsha peripheral, dhau los ntawm dorsal cag ganglion (DRG) thiab mus rau tus txha caj qaum. … Spike ntxeem tau ntawm soma nyob rau hauv nruab nrab paj hlwb neurons yuav ua tau zoo sib xws. https://pubmed.ncbi.nlm.nih.gov › …
Hluav taws xob excitability ntawm soma ntawm kev hnov mob neurons yog xav tau rau …
muaj nyob rau hauv txhua txheej ntawm daim tawv nqaij Muaj rau ntau hom mechanoreceptors ntes cov stimuli innocuous nyob rau hauv daim tawv nqaij: cov nyob ib ncig ntawm cov plaub hau follicles, Pacinian corpuscles, Meissner corpuscles, Merkel complexes, Ruffini corpuscles, thiab C. - fiber ntau LTM (tsawg pib mechanoreceptors).
receptors nyob rau hauv daim tawv nqaij nyob qhov twg?
daim tawv nqaij receptors nyob ze cov pob qij txha thiab cov ntaub so ntswg sib sib zog nqusuas teb rau lub siab, kev co, thiab lub suab nrov.
Yuav ua li cas kov receptors nyob rau hauv daim tawv nqaij?
Muaj peb lub ntsiab ntawm cov receptors hauv peb daim tawv nqaij: mechanoreceptors, teb rau cov neeg kho tshuab stimuli, xws li stroking, ncab, lossis kev co ntawm daim tawv nqaij; thermoreceptors, teb rau qhov txias lossis kub kub; thiab chemoreceptors, teb rau qee hom tshuaj siv los yog tso tawm …
Peb cov tawv nqaij muaj pes tsawg leeg?
Txhua square centimeter ntawm koj daim tawv nqaij muaj nyob ib ncig ntawm 200 qhov mob receptors tab sis tsuas yog 15 receptors rau siab, 6 rau txias thiab 1 rau sov.
Puas kov receptors pom tsuas yog hauv daim tawv nqaij?
Nws muaj plaub qhov tseem ceeb tactile mechanoreceptors hauv tib neeg cov tawv nqaij: Merkel's disks, Meissner's corpuscles, Ruffini endings, thiab Pacinian corpuscle; ob yog nyob rau ntawm daim tawv nqaij thiab ob yog nyob rau hauv tob. Ib hom thib tsib ntawm mechanoreceptor, Krause kawg qhov muag teev, pom tsuas yog hauv thaj chaw tshwj xeeb.
