Isingeniso: Kungani Izinyoni Zilala Ziphendule Amakhanda?
Uma uke wabona izinyoni zilele, kungenzeka uye waqaphela ukuthi zivame ukuphendulela amakhanda azo futhi zifake imilomo yazo ezimpapheni zazo. Lokhu kuziphatha akukona nje kuphela ohlotsheni oluthile lwezinyoni, kodwa kuyisici esivamile emhlabeni wonke wezinyoni. Kodwa wake wazibuza yini ukuthi kungani izinyoni zilala ziphendule amakhanda? Kulesi sihloko, sizohlola i-anatomy yentamo nomgogodla wenyoni, izisekelo zokuthi izinyoni zilala kanjani, kanye nemibono kanye nezincazelo zokuphenduka kwekhanda lezinyoni ezihlobene nokulala.
I-Anatomy Yentamo Nomgogodla Wenyoni
Izinyoni zinesakhiwo esiyingqayizivele samathambo esizivumela ukuthi zindize futhi zenze okunye ukuqondisa kwendiza. Izintamo zabo zakhiwe ama-vertebrae angu-14-25, kuye ngokuthi hlobo luni, olungaphezu kwama-vertebrae ayisikhombisa atholakala entanyeni yomuntu. Ukwengeza, ama-vertebrae entanyeni yenyoni ahlanganiswe ndawonye futhi anezinhlobo eziningi zokunyakaza, okuwavumela ukuba anyakaze amakhanda awo cishe kunoma iyiphi indlela.
Izinyoni zibuye zibe nomgogodla oguquguqukayo, obalulekile ekundizeni. Ngokungafani nezilwane ezincelisayo, ezinomgogodla oqinile, izinyoni zinamalungu alandelanayo ahambisana nomgogodla azivumela ukuba zigobe futhi zisonteke emoyeni. Lokhu kuvumelana nezimo kubuye kubenze bakwazi ukulala ezindaweni ezihlukahlukene futhi baphendule amakhanda abo ngaphandle kokubeka umthwalo omningi ezintamo zabo.
Izinyoni Zilala Kanjani: Okuyisisekelo
Izinyoni zinephethini yokulala eyingqayizivele uma kuqhathaniswa nezilwane ezincelisayo. Esikhundleni sokulala ubuthongo obukhulu, izinyoni zingena esimweni sokulala kancane lapho i-hemisphere eyodwa yobuchopho bazo ihlala iqaphile kuyilapho enye i-hemisphere ilele. Lokhu kuvumela izinyoni ukuthi zihlale ziqaphile izilwane ezidla ezinye noma ezinye izinsongo kuyilapho zisakuthola ukuphumula ezikudingayo.
Izinyoni zingalala ezindaweni ezihlukahlukene, ezihlanganisa ukuhlala egatsheni noma unqenqema, ukuma ngomlenze owodwa, noma ngisho nokuntanta emanzini. Zivame ukufaka amakhanda azo ezimpapheni noma ezimpikweni ukuze zifudumale futhi zivikele amehlo azo ekukhanyeni kwelanga noma emvuleni.
Ukulala Ngeso Elilodwa Vula: Izinzuzo
Njengoba kushiwo ngaphambili, izinyoni zilala zivule iso elilodwa ukuze zihlale ziqaphe ingozi. Leli khono lokulala nehlo elilodwa livuliwe kungenxa yezinyoni ezinesitho esikhethekile esibizwa ngokuthi i-pecten oculi, esizivumela ukuba zigcine iso elilodwa livaliwe kuyilapho zisathola okokubonayo. Lokhu kuzivumela ukuthi zibone izilwane ezidla ezinye ezidla ezinye noma ezinye izinsongo kuyilapho zisathola ukuphumula ezikudingayo.
Ukuphenduka Kwekhanda Okuhlobene Nokulala: Imibono Nezincazelo
Kunemibono nezincazelo eziningana zokuthi kungani izinyoni ziphendulela amakhanda lapho zilele. Omunye umbono uwukuthi uyazisiza ukuthi zilondoloze ukushisa komzimba ngokufaka imilomo yazo ezimpapheni zazo. Enye inkolelo-mbono ukuthi iyabasiza ukuthi bahlale belinganisela ngenkathi belele e-perch noma egatsheni. Ukwengeza, ukuphendulela amakhanda abo kungase kuzisize zigweme izilwane ezidla ezinye ngokugcina i-watchout ezindaweni ezahlukene.
Umsebenzi Wenkabazwe Yengqondo Ezinyoni Ezilele
Njengoba kushiwo ngaphambili, izinyoni zingena esimweni sokulala kancane lapho i-hemisphere eyodwa yobuchopho bazo ihlala iqaphile kuyilapho enye i-hemisphere ilele. Lokhu kwaziwa njenge-unihemispheric slow-wave sleep, futhi kuvumela izinyoni ukuthi zihlale ziqaphile izilwane ezidla ezinye noma ezinye izinsongo kuyilapho zisakuthola ukuphumula ezikudingayo.
Izilwane Ezizingelayo Nezisulu: Ukubaluleka Kokuqapha
Izinyoni ziyizilwane ezidla ezinye futhi zidla embusweni wezilwane. Lokhu kusho ukuthi badinga ukuqapha ngaso sonke isikhathi, ngisho nalapho belele. Ngokulala ngeso elilodwa livuliwe futhi ziphendule amakhanda azo, izinyoni zingahlala ziqaphela indawo ezizungezile futhi zithole izilwane ezidla ezinye ezingaba izilwane noma izilwane ezizingelayo.
Ukuphenduka Kwekhanda Okuhlobene Nokulala Ezinhlotsheni Ezihlukene Zezinyoni
Ukuphendula ikhanda okuhlobene nokulala kuwukuziphatha okuvamile kuzo zonke izinhlobo zezinyoni. Isibonelo, izikhova zaziwa ngokuzungeza amakhanda azo aze afike ku-270 degrees, okuzivumela ukuthi zibone cishe noma yikuphi. Amaphengwini abuye aphendule amakhanda awo lapho elele, afake imilomo yawo ezimpapheni zawo ukuze afudumale.
Iqhaza Lokulala Ekufudukeni Kwezinyoni
Ukufuduka kuyingxenye ebalulekile yokuphila kwezinhlobo eziningi zezinyoni. Ngesikhathi sokufuduka, izinyoni zidinga ukundiza amabanga amade ngaphandle kokuma ukuze ziphumule. Ukuze kunxeshezelwe lokhu, izinyoni zingase zingene esimweni sokungalali kahle kwegagasi elihamba kancane lapho zindiza, okuzivumela ukuba zihlale ziqaphile izilwane ezidla ezinye kuyilapho zisakuthola ukuphumula ezikudingayo.
Ukuphendula Ikhanda Okuhlobene Nokulala Ezinyoni Ezithunjiwe
Ukuphenduka kwekhanda okuhlobene nokulala akugcini ezinyonini zasendle. Izinyoni ezithunjiwe, njengalezo ezigcinwe kuma-zoo noma njengezilwane ezifuywayo, nazo zibonisa lokhu kuziphatha. Kodwa-ke, izinyoni ezithunjiwe zingase zingabi nesidingo esifanayo sokuqapha njengezinyoni zasendle, futhi ukuphenduka kwazo okuhlobene nokulala kungase kuhlobane kakhulu nokunethezeka noma umkhuba.
Isiphetho: Ukuqonda Ngemikhuba Yokulala Yezinyoni
Izinyoni zinemikhuba yokulala eyingqayizivele ezivumela ukuthi zihlale ziqaphile kuyilapho zithola ukuphumula ezikudingayo. Ukuphendula ikhanda okuhlobene nokulala kuwukuziphatha okuvamile kuzo zonke izinhlobo zezinyoni, futhi kungase kufeze izinjongo ezimbalwa, njengokugcina ukushisa komzimba, ukuhlala ulinganisele, noma ukugwema izilwane ezidla ezinye. Ukuqonda imikhuba yokulala yezinyoni kungasisiza ukuthi sizazise kangcono lezi zilwane ezithakazelisayo nokuzivumelanisa kwazo nezimo.
Ucwaningo Olwengeziwe: Imibuzo Engaphendulwa Neziqondiso Ezizayo
Nakuba kuningi okwaziwayo mayelana nemikhuba yokulala yezinyoni, kusekuningi okufanele kufundwe. Ucwaningo lwesikhathi esizayo lungahlola izindlela ezingemuva kokulala kwegagasi elihamba kancane kwe-unihemispheric, imiphumela yokuthunjwa ekuphenduleni ikhanda okuhlobene nokulala, kanye nendima yokulala ekuxhumaneni kwezinyoni. Ngokuqhubeka nokuphenya imikhuba yokulala yezinyoni, singathola ukuqonda okwengeziwe kwalezi zilwane eziphawulekayo nokuzivumelanisa kwazo.
