E Kei receptors i roto i te kiri. Ratou hanganga me te mahi

I roto i to tatou kiri tinana he wāhi mata katoa o 1.5 m ² me 2.5 m ^2, operably hono ki nga whekau, me te whakaata ratou mana rite tikanga noa, me te pathological. Ki te hanganga e toru-apa matatini, kei reira te kūmuri io, te mau farii ohipa kiri kia huaina kite whakaohooho i te taiao o waho. Ka tamata tēnei tuhinga ki te whakahoki i te tahi mau uiraa. E receptors e kei roto i te kiri? O ratou hanganga me te mahi? Kia pehea te Ko te pāhekoheko i waenganui i te tinana tangata, me ngā āhuatanga i te taiao tūturu integuments.

E receptors e kei roto i te kiri

Anatomy me whaiaroaro te ako kore anake nga pūnaha nui o te tinana, engari ano ki te hunga e e kei receptors i roto i te kiri. Biology (Grade 8) whakamārama i te āhuatanga morphological me mahi o te pūnaha pūoko tūturu, e hāngai ana i runga i nga pau o te hanganga me ngā mahi o te momo ngā o receptors kiri, ngā reira.

I roto i te mau farii ohipa kiri e o toru ngā momo: mechanoreceptors thermoreceptors me nociceptors (mamae). Kei te whakamutunga i roto i nuinga o te wā i roto i te kiriwaho - te kahu waho o te kiri, arā, o te epithelium, Kei te maha o ngā rarangi i roto i. Ko te wahi o runga o te whāriki, exfoliated ka whakakapia i te utu o nga paparanga o raro. I roto i te tangata, kei te tata rawa whakahoutia nga kiriwaho puta noa te marama.

Ko te tuatahi e rua ngā momo - mechanoreceptors me thermoreceptors - motuhake te nuinga i roto i te kiri ranei hiako ake, i roto i te kahu o o tūhonohono kiko, i roto i katoa o tona hanganga ngā huānga, whai wāhi toto me te tīpona oko, huruhuru me te repe peke.

Receptor mahi o te kiri

mahi kiri tangata e rave rahi mahi nui, tetahi o i ko te receptor. Ko reira no te mea he mara receptor, e te kaiwhakawhiwhi te pūnaha io pokapū rite te kōrero e pā ana ki ngā rerekētanga i roto i te kiri iho, me e pā ana ki te āhua o te whakaohooho nga arai tinana. ngā tinana Active e pā ana ki etahi wāhi o te roro, a roto i a ratou ki te pūnaha musculoskeletal me whekau.

e kore e atu atu i te wahi piringa o analyzer musculocutaneous, ano nei ngā nga raru e mau ana i te wahi excitation o receptors me pokapū i roto i te roro, e kei i runga i tona wahi kātua receptors kiri. Ka rite ki whakahuatia i mua, te mau farii ohipa o te analyzer kiri kei roto i te kiriwaho me te kiri ano. Ratou hanganga me ngā mahi e te taua.

Hei tauira, receptors tūturu - Meissner corpuscles, he tohu e whakatau te tere o te pa, me te e kei i roto i nga kiriwaho, me te kuao kau Pachchini e te hunga hohonu i roto i te kiri, te kawenga mō te huringa whakatere o whakaohooho tūturu. Tei sensation pūāhua kore anake i runga i te aha te huru o receptors i roto i te kiri kite te pānga o te taiao o waho, engari ano hoki i runga i te auau o te faaitoitoraa. Ki te he te reira mo te tamau wa roa, i reira te mea he ongo o te pēhanga ka mahi taratahi - pa, me te kaha nui o te huringa auau whakahihiko - wiri sensation.

Te huru paepae raro o receptors kiri kei i runga i te matamata o te arero me ngutu, teitei - i runga i nga matimati, te nikau, nga hipi ā o nga tuke, me te paepae teitei He puku kiri, waewae, me te hoki.

receptors pāmahana Āhuatanga

Temperature receptors whakahaere te taumata noa o te tauhohe o te pākia e homeostasis. E tū ana i roto i nga taiepa o pera, me te whakarato pāmahana ture - whakataurite i te tukanga o te whakawhitinga wera kaiao homeothermic he pāmahana taimau o te tinana. Ko te kupu, ko te kahu urutaunga o te kaiao ora tei runga i nei e kei receptors i roto i te kiri, me te pehea hohoro tohu ratou huringa i roto i te taiao.

Ko te pū o nociceptors

Ko te ako o te take, e kua kei receptors i te kiri, e kia oti ki te kore i whakaaro tatou nga peculiarities o te hanganga o receptors mamae. Anga ke ki te pānuitanga rongoā, helpfully whakahere kotahi me mo kia whakakahoretia atu katoa o te mamae, i kite mātou i tenei mamae ko te whakautu paruru o te tinana, te faaiteraa ia o mōrearea pea. Nociceptors i te puka o kotahi mutunga karere branched, iteraa i te momo rawa kaha wera whakaohooho, te pēhanga, matao. Ko to ratou rahinga nui i runga i nga fingerpads, he kiriuhi wheua, he taiepa oko toto i roto i te arachnoid roro.

Ka taea te tukinotia mamae rite te ahua o te perception tūturu, na ko te mea nui i receptors kei roto i te kiri e kore e anake, engari ano hoki te pai o te whakautu ratou ki akiaki kaha. kite te mana'o o te mamae e rite te mana'o tuakiri e faaite tatou i te hunga i roto i te kāwanatanga ngā kino psycho-aronganui. Kei te whakapataritari te reira e whakaawe akiaki motuhake modality tairongo.

arotake tenei tuhinga i te hanganga āhuatanga me ngā mahi o te mau farii ohipa o te kiri.
