Kungani inja idinga amadevu?

Kuyavunywa ukuthi izinja zinezinzwa eziyisithupha eziyinhloko: ukunambitha, ukuhogela, ukubona, ukuzwa, ukulinganisa kanye nokuthinta. Ngezinhlanu zokuqala, yonke into icacile kakhulu: amehlo anesibopho sombono, izindlebe zinesibopho sokuzwa, ikhala libhekene nephunga, futhi i-vestibular apparatus inesibopho sokulinganisela. Kodwa izitho zokuthinta ezinjeni nakubantu zihluke kakhulu.

Uma uyibhekisisa inja, ungabona izinwele ezijiyile ekhanda layo. Zitholakala ngenhla kwamehlo, ezihlathini, ezindebeni, nasemakhoneni omlomo. Ukuze uqonde ukuthi kungani inja inamadevu ebusweni bayo, kufanele uphendukele ku-biology.

Yini ama-vibrissae futhi asebenza kanjani?

Ngolimi lwesayensi, amadevu ezinja abizwa ngokuthi ama-vibrissae. Ziyizinwele ezizwela kakhulu. Emakatini, ngokwesibonelo, umehluko phakathi kwezinwele nentshebe usobala futhi uyamangalisa, kodwa amadevu ezinja mafushane kakhulu futhi athambile. Noma kunjalo, banenhloso eyodwa: bayisitho sokuthinta, okungukuthi, ngosizo lwabo, inja, njengekati, iziqondisa emkhathini, inquma ubukhulu bezinto eziseduze nayo, izwa amandla nesivinini somoya. . Ngokuvamile, basiza isilwane ukuthi sibone umhlaba osizungezile kangcono.

Ama-mustache follicles - izinwele ezibucayi - ziyinkimbinkimbi yama-mechanoreceptors. Kalula nje, zizungezwe amashumi ezinkulungwane zezinzwa ezibona ukushukunyiswa komshini futhi zithumele izimpawu ezifanele ngakho ebuchosheni benja.

Eqinisweni, izinwele ezibucayi azitholakali kuphela emlonyeni wesilwane, kodwa kuwo wonke umzimba. Nokho, awamukelwa njenge-vibrissae. Kodwa-ke, kufanele kuqashelwe ukuthi izinwele ezinjalo eziqinisiwe zineziphetho eziningi ze-nerve ku-follicle futhi zingabokuqala ukuphendula ekuvuseleleni kwangaphandle.

Ungakwazi yini ukunquma amadevu enja?

Ngezinye izikhathi abanikazi bezinja, ngenxa yokungazi noma ngokusekelwe kulokho abakuthandayo, bacela umkhwenyana ukuba anqume amadevu abo. Lokhu kungachazwa kuphela yiqiniso lokuthi abanikazi abanjalo abazi ukuthi kungani izinja zidinga amadevu, ngaphandle kwalokho ngeke neze bakwenze.

Izinja ezishiywe ngaphandle kwentshebe zilahlekelwa ukuma kwazo emkhathini. Isignali evela ku-vibrissae iba iphutha noma iyeka ngokuphelele ukuza ebuchosheni.

Ngenxa yalokhu, ngokuvamile izinja ziba novalo futhi zicasuke, zingase zibe nokuhlaselwa kaningi kolaka. Ukulahlekelwa amadevu kuyingozi ikakhulukazi ezilwaneni ezifuywayo ezindala, ezinzwa zazo zokuhogela nokuzwa sezivele zifiphele, futhi isimiso sezinzwa esimaphakathi ngokuvamile siyehluleka.

Namuhla, impilo yesilwane ibekwe kuqala, futhi, isibonelo, emibukisweni, kukhona ukuvinjelwa okukhulayo kokusika amadevu ezilwane.

Yini okufanele uyenze uma amadevu enja ewa?

Kumelwe ngisho ukuthi ukulahlekelwa okukodwa kuyisenzakalo semvelo, "isikhathi sokuphila" se-vibrissa cishe iminyaka engu-1-2. Kodwa, uma ubona ukuthi amadevu asephenduke aba mhlophe noma aseqalile ukuwa ngobuningi, kufanele uxhumane nodokotela wakho wezilwane.

Inqubo yokulahlekelwa amadevu ingase ihlotshaniswe nezinguquko ze-hormonal - isibonelo, ngesikhathi sokukhulelwa, i-lactation noma i-estrus. Ngaphezu kwalokho, inkinga ingase ibe ngenxa yokuphelelwa amanzi emzimbeni noma umoya owomile. Kukhona nezizathu ezimbi kakhulu - izinhlobo ezahlukene zezifo. Ukukhipha isifo sesilwane, vakashela umtholampilo wezilwane, ngoba inkinga yokulahlekelwa amadevu ingabangela izinkinga eziningi esilwaneni.
