Chii chinonzi Kanotokonya? Types uye chinangwa receptors

Nyaya inotsanangura kuti receptors dzakadaro, ravakanga kushumira murume uye, kunyanya, dingindira Kanotokonya mhandu.

bhayoroji

Upenyu redu pane makore anenge mabhiriyoni 4. Panguva iyi zvisinganzwisisiki kuvanhu maonero upenyu pamusoro payo chikatsiviwa zhinji mhando, uye pamwe izvi uchaenda nokusingaperi. Asi kana ukatarira esayenzi maonero upi zvipenyu muviri, ipapo ayo mamiriro, coherence uye kunyange chaizvo nokuvapo zvinoshamisa, uye chokuita kunyange inokosha siyana. Uye nezvomuviri womunhu, uti chinhu! Chero nzvimbo yaro zvipenyu kunoshamisa uye hunakidze.

We funga pepa rino kuti receptors dzakadaro, nei vari kudiwa uye chii chichaitika. Mukuita kudaro, tinoedza kunzwisisa zvizere sezvataigona.

kushanda

Maererano enisaikoropidhiya, iyo Kanotokonya - yesangano of harinzwi tsinga fibers mune dzimwe Tutsinga tunofambisa mashoko utwu nedzimwe nehanya uye yakananga inotungamirwa pakati intercellular fuma uye masero yekuverengera tishu mupenyu. Pamwe chete vakazvipira kutsausa kukanganiswa zvinokonzera akasiyana-siyana, izvo kazhinji vachinzi kuitika, kunyanya tsinga zvatinganzwa. Zvino tinoziva kuti Kanotokonya ichi.

Dzimwe mhando receptors dzevanhu kunzwisisa mashoko uye kuona kuburikidza anokosha masero epithelial mavambo. Mukuwedzera, muna nokurera mashoko pamusoro mikana yakawanda yokukurudzira zvinobatanidzwa uyewo dzakachinjwa masero etsinga, asi musiyano pakati pavo kuti vaunze tsinga nomunhu havagoni voga, asi chete kuita innervate mugumo. By kuravidza Mafundo (vari riri epithelium rurimi pamusoro) muenzaniso saka unoshanda. Zvavakaita kwakavakirwa chemoreceptors ndivo mhosva maonero uye mabatiro yokuwana kwemakemikari kana kugadzikana zvinhu.

Zvino tinoziva chii kunaka namabukira uye sei avanoshandira.

sarudzo

Zvichitaurwa zviri nyore, kuti receptors vane basa basa anenge ose pfungwa. Uye kunze kwazvo pachena, zvakadai kuona kana kunzwa, dzinoita kuti munhu anzwe uye dzimwe mananara: kumanikidzwa, tembiricha, mwando zvichingodaro. Saka takakurukura mubvunzo kuti chii receptors. Asi tarisai navo zvizere.

Mikana yakawanda yokukurudzira kuti Activate zvimwe receptors vanogona kushumira zvakasiyana chaizvo zvinokonzerwa nezviito, somuenzaniso zvemaziso ehupfumi ari deformation (maronda uye maronda), hasha makemikari, uye kunyange yemagetsi kana remagineti! Zvisinei, chii receptors ndivo mhosva maonero kare, asi kwete chaiyo kutsunga. We chete kuziva kuti pane zvechokwadi vakadaro, asi mune dzose dzakasiyana.

mhando

Vari rakakamurwa mhando maererano nzvimbo mumuviri uye anotikurudzira, iyo yatinoswedera nokugamuchira zviratidzo zviri etsinga harinzwi. Funga zvakadzama Kanotokonya kupatsanura pokugara anotikurudzira:

• Chemoreceptors - vane basa zvakabikwa uye munhuwi basa ravo kwakavakirwa matambudziko kugadzikana uye nemamwe makemikari.
• Osmoreceptors - munyaya Pakusarudza shanduko iri osmotic fluid kureva kuwedzera kana kuderera .. Osmotic kumanikidzwa (ichi zvemarudzi pachiyero pakati intracellular uye extracellular zvinwiwa).
• Mechanoreceptors - nokugamuchira zviratidzo yakavakirwa panyama migumisiro.
• Photoreceptors - ngaaongwe kwavari kuti maziso edu kutora rinooneka chiedza chakarondedzera.
• Thermoreceptors - vane basa omumwe tembiricha.
• Nociceptors.

Chii Kanotokonya mhandu?

Zvichitaurwa zviri nyore, vaya zvinhu izvo zvinogona kusungira kuti receptors, asi handishanduki mberi kwavo. A agonist nekusiyana, kwete chete runokusunganidzai asiwo nokushingaira paupenyu Kanotokonya. Somuenzaniso, yokupedzisira inosanganisira vamwe zvinodhaka zvinoshandiswa yokutindivadza. Ivo kunyimwa nehanya yacho Kanotokonya. Kana dzinonzi haasaruri, uye chiito avo kukwana.
