Amehlo ethu amangalisa kangakanani? Ake sifunde nge-eye reflexes!

Wake wazibuza ukuthi zingaki izinto amehlo ethu azenzayo ngaphandle kokuthi siqaphele? Kufana nomlingo omncane. Akugcini nje ngokukusiza ukuthi ubone, kodwa futhi kusebenza ngokuzenzakalelayo ukuvikela amehlo akho. Yilokhu esikubiza ngokuthi "Eye Reflexes ." Lezi zinto zenzeka ngokuzenzakalelayo, okusho ukuthi akudingeki uzilawule noma ucabange ukuthi, "Yile ndlela okufanele kube ngayo."

Kuyini ukusabela kwamehlo? Kungani kubalulekile?

Kalula nje, ama-eye reflexes awuchungechunge lwezinguquko ezenzeka ngokuzenzakalelayo emehlweni akho. Aklanyelwe kakhulu ukukusiza ukuthi ubone kahle futhi uvikele ama-eyeballs akho ekulimaleni . Cabanga ngokuthi kuzokwenzekani uma ungabuka ukukhanya okukhulu ngokuzumayo noma uma ukungcola kungena esweni lakho. Amehlo akho asabela kukho ngaphambi kokuba ucabange ngakho. Yilokho ama-reflexes ayikho.

Amehlo ethu ayizitho eziyinkimbinkimbi kakhulu. Izingxenye eziningi zeso zisebenza ndawonye ukuze zigxilise lokho esikubonayo futhi zithumele lolo lwazi olubonakalayo ebuchosheni. Ngakho-ke lezi zi-reflex yizo ezivikela amehlo akho futhi zisize amehlo akho ukuba azivumelanise nezimo ezahlukene zokukhanya. Zisiza ekuvimbeleni umbono wakho ukuthi ungafiphali ngisho nalapho uhambisa amehlo akho ngokushesha noma lapho ukukhanya kushintsha ngokuzumayo.

Ukusabela okuthile kubangela ukuthi amehlo akho anyakaze noma ashintshe ngenxa yezinto ezenzeka eduze kwakho. Izingxenye eziningi zeso lakho zinegalelo kulokhu kusabela. Isibonelo:

• Umfundi : Lena yingxenye encane, emnyama eyindilinga enkabeni yeso.
• I-Cornea : Ulwelwesi olubonakalayo ngaphambili kweso.
• Uhlelo Lokudabuka : Uhlelo olukhiqiza futhi lukhiphe izinyembezi.
• I-Ocular Nerve : I-nerve ehlobene nokubona.

Futhi, ezinye izinzwa zamehlo zenzeka ngenxa yezinguquko kwezinye izingxenye zomzimba wakho. Lokhu kufaka phakathi:

• Imisipha
• Imizwa
• Uhlelo Lwezinzwa

Uma uya kudokotela wamehlo, uzohlola nalezi zinzwa lapho ehlola amehlo akho. Udokotela uzonaka kakhulu lezi zinzwa ezithile, ikakhulukazi uma unezimpawu noma uma unezinkinga ngamehlo akho noma umbono wakho.

Zisebenza kanjani lezi zinzwa zokuzivuselela? Kuyamangalisa!

Amaseli akhethekile ezinzwa adlulisela ukusabela kwamehlo ebuchosheni bakho bese ebuyela emehlweni akho.(`Amaseli Emizwa`) kuya ezimpawini zikagesi ezihamba ngazo. Cabanga ngakho njengokuthi `ukucindezela` ukhiye` ku-`ikhibhodi yekhompyutha`. Uma `ucindezela` ukhiye`, isignali kagesi ihamba ngocingo iye ku-`ikhompyutha` bese iyibonisa njengohlamvu esikrinini, akunjalo? Kodwa okwenzekayo lapha akufani nokuthi `uthayipha` uhlamvu ngalunye. Ngaphandle kokuba nesikhathi sokucabanga, amehlo akho ahlala elolongwa futhi evikelwe ngalezi zinzwa.

Izindlela ezihamba ngazo lezi zimpawu zakhiwe ngezinto ezifana nalezi:

• Izinzwa (`AMA-RECEPTOR`): Lezi yizo zokuqala ukubona izinto ezishukumisayo.
• Ama-Neuron ahlukile: Lawa athwala izimpawu ezivela ezinzwa ziye ebuchosheni.
• Ama-Neuron asebenzayo: Lawa athwala izimpawu ezivela ebuchosheni zibuyele emisipheni noma endlaleni efanele.
• Ama-Effectors: Lezi yizingxenye eziphendula ekugcineni (isb., ukufinyela kwemisipha).

Cabanga ngakho njengochungechunge lwezixhumanisi. Esinye asinakusebenza ngaphandle kwesinye. Konke kufanele kuhlanganiswe kahle.

Yiziphi izinhlobo zokusabela okubonakalayo esweni? Ake sibheke.

Kunezinhlobo eziningana eziyinhloko ze-reflexes emehlweni ethu. Ake sixoxe ngazo ngayinye ngayinye.

• Ukuzindla Kwe-Pupillary
• Ukuzindla kwe-Corneal
• I-reflex ye-Vestibulo-ocular
• I-Oculocephalic Reflex (ebizwa nangokuthi "i-Doll's Eye Reflex")
• I-Palpebral Oculogyric Reflex (ebizwa nangokuthi i-Bell's Reflex)

Ukuzindla Kwe-Pupillary

Ingxenye emnyama ephakathi neso lakho ibizwa ngokuthi umfundi . Kungenzeka ukuthi uke waphawula ukuthi ngezinye izikhathi iba nkulu futhi ngezinye izikhathi iba ncane. Lokhu kwenzelwa ukulawula inani lokukhanya okungena esweni. Imisipha engxenyeni enombala yeso lakho, i-iris, ilawula usayizi womfundi. Lesi senzo sokuguquguquka sibangela umfundi wakho ukuthi ashintshe usayizi ngokuzenzakalelayo ngaphansi kwezimo zokukhanya ezahlukene. Lokhu kubizwa nangokuthi 'indawo yokuhlala ye-pupillary'. Lokhu kwenzelwa ukugcina umbono wakho uzinzile ngaphansi kwezimo ezahlukene. Okusho ukuthi, ilawula ukuthi kukhanya okungakanani okungena esweni futhi kuwele ku- 'retina' .

I-iris inezindlela eziningana zokusabela:

• I-Reflex Yokukhanya Kwabancane:Yilokhu okwenzekayo lapho imbobo yakho yeso ifinyela (iba ncane) ekukhanyeni okukhulu. Lapho ukukhanya okukhulu kushaya iso lakho, imisipha ese-iris ifinyela ngokuqinile, icindezele imbobo. Cabanga nje, uma ungena ngaphakathi ngokuzumayo usuka endaweni enelanga, amehlo akho azozizwa eluhlaza okwesibhakabhaka isikhashana, kuze kube yilapho imbobo yakho ivuleka futhi ijwayele ubumnyama.
• I-Pupillary Dark Reflex: Lokhu kwenzeka lapho umfundi wakho evuleka khona (eba mkhulu) uma uya endaweni emnyama. Lokhu kubangela ukuthi imisipha ese-iris iphumule, okuvumela ukukhanya okwengeziwe ukuthi kungene esweni.
• I-Ciliospinal Reflex: Lena ihlukile kancane. Uma kukhona okushaya ebusweni noma entanyeni, okusho ukuthi uzwa ubuhlungu noma ukuthintwa, izitho zakho ziyavuleka.

Ukuzindla kwe-Corneal

I-cornea yingxenye yeso lakho ecacile, efana nefasitela. Yenziwe ngezicubu eziqinile, ezicacile. Kanye nengxenye emhlophe yeso (ebizwa ngokuthi i-sclera ), i-cornea isiza ekuvikeleni iso lakho. I-cornea inemisebenzi emibili:

• I-Blink Reflex: Njengoba igama lisho, lokhu kuyindlela yokuzivumelanisa nezimo ebangela ukuba amehlo akho avaleke ngokuzenzakalelayo lapho okuthile kuthinta i-cornea yakho. Cabanga nje, ucwayiza ngokungazi lapho uthuli lungena esweni lakho, akunjalo? Yilokho kuphela.
• I-Tear Reflex (`I-Tear Reflex` / `I-Lacrimatory Reflex`): Lokhu kwenzeka nalapho okuthile kuthinta iso lakho. Uhlelo lwakho lwezinyembezi lugcwalisa iso lakho ngezinyembezi ezintsha, luhlanze noma yini enamathele ngaphakathi.

Uma i-eyelash iwela esweni lakho, uhlangabezana nazo zombili lezi zindlela zokusabela kwe-cornea. Ngaphambi kokuthi uqaphele, iso lakho liyavaleka, bese kuthi ngokuzumayo iso lakho ligcwale izinyembezi, lizigeze. Lokhu akuyona nje into eyenzeka esweni lakho, kodwa kunezinye izikhathi lapho lokhu kusabela kokucwayiza noma ukudabuka kuqala khona. Isibonelo:

• Ukukhanya okukhanyayo
• Uma uzizwa udangele noma ukhathazekile
• Uma kufika ukukhwehlela
• Uma uhlanza
• Uma umoya obandayo uvunguza

I-Vestibulo-ocular reflex (Vor)

Amehlo ethu alawulwa yimisipha eyisithupha ewashukumisa kusukela ohlangothini olulodwa kuya kolunye, phezulu naphansi. Yilokhu okusenza sibone njengoba sifuna. Le misipha efanayo ishukumisa namehlo ethu kulokho okubizwa ngokuthi i-'Vestibulo-ocular Reflex' . Lapho ikhanda lakho linyakaza, ubuchopho bakho kanye ne-'Oculomotor Nerve' kwenza ngokuzenzakalelayo ukulungiswa okuncane emisipheni yamehlo akho. Ngisho noma ungacabangi ngakho, ikhanda lakho liyanyakaza ngaso sonke isikhathi, ikakhulukazi uma uhamba, ugijima, noma wenza noma yimuphi omunye umsebenzi womzimba. Ngakho-ke, lapho ikhanda lakho linyakaza, yi-vestibulo-ocular reflex esiza ukugcina amehlo akho esezingeni elifanayo. Cabanga, ukube ubungenalo lolu hlobo lwe-reflex, umbono wakho ubuyohlala ungacacile, njengokungathi uhamba ngesikebhe olwandle olunamagagasi.

I-Oculocephalic Reflex (I-Doll's Eye Reflex)

Lena indlela kadokotela wamehlo yokuhlola ukuthi izinzwa zakho ze-cranial zisebenza kahle kangakanani. Ibizwa nangokuthi i-doll's eye reflex . Lokhu `ukuhlolwa kwamehlo okwamukela`, okuwukuhlolwa kokunyakaza ukuze kubonwe ukuthi amehlo akho avumelana kahle kangakanani nezinguquko. Uma udokotela ehlola i-`Doll's Eye Reflex` yakho, uzobamba izinkophe zakho bese ephendula ikhanda lakho ngokushesha ukusuka kolunye uhlangothi kuya kolunye. Ngemuva kwalokho, noma ikhanda lakho lihamba, amehlo akho azojwayela ngokuzenzakalelayo ukubheka phambili. Uma umbono wakho uba mubi kakhulu ngesikhathi sokuhlolwa , noma uma amehlo akho ehamba kakhulu, okuthile kungase kuphazamise izinzwa noma imisipha esiza ukugcina amehlo akho ezinzile. Udokotela kuzodingeka enze ukuhlolwa okwengeziwe ukuze athole ukuthi yini ngempela ethinta amehlo akho.

I-Palpebral Oculogyric Reflex (i-Bell's Reflex)

Lokhu kwenzeka lapho othile ezama ukuthinta amehlo akho noma awaphoqe ukuba avale, okubangela ukuthi ugoqe amehlo akho ngokungazi. Lokhu kubizwa nangokuthi i-Bell's Reflex . Uma wake wagoqa amehlo akho lapho ufaka ama-contact lens noma ufaka umuthi wamehlo, kungenzeka ukuthi uke wabhekana nalokhu. Abanye abantu baze babe nalesi si-Bell's Reflex lapho befaka izimonyo.

Ngokungafani nezinye izindlela zokubona ngamehlo, i-Bell's Reflex ayikusizi ngalutho ukubona kwakho noma ukuvikela amehlo akho. Ochwepheshe bakholelwa ukuthi iyindlela yokuzivikela eyakhelwe emizimbeni yethu. Abantu abakhubazekile ebusweni, njenge- Bell's Palsy, abanayo i-Bell's Reflex. Kodwa-ke, ukungabi ne-Bell's Reflex akusho ukuthi kukhona okungahambi kahle ngamehlo akho. Eqinisweni, cishe u-10% wabantu abanayo ngokwemvelo i-Bell's Reflex.

Yiziphi izimo nezinkinga ezivamile ezithinta ukusabela kwamehlo?

Noma yini elimaza amehlo akho, imisipha, imizwa, noma ubuchopho ingathinta i-eye reflex yakho. Nazi ezinye zezinkinga ezingaphazamisa i-eye reflex yakho:

• Ukulimala Kwamehlo
• I-Neuropathy
• Ukushaya kwenhliziyo
• Ukukhubazeka
• Isifo Esinsundu
• Isifo sikaHorner
• I-Strabismus (amehlo ahlanganiswe nge-cross)
• I-Nystagmus (ukudlidliza kwamehlo)

Okokugcina, izinto okufanele uzikhumbule

Amehlo akho ayindlela ebaluleke kakhulu yokuxhumana nomhlaba okuzungezile. Ngisho noma ungacabangi ngakho, amehlo akho avikelwe futhi alawulwa yi-reflexes. Agcina ngokuzenzakalelayo umbono wakho uzinzile, avikele izicubu zamehlo akho ekulimaleni, futhi akuvikele ezintweni zangaphandle.

Ngisho noma ungazilawuli ngamabomu lezi zinto, uma kukhona okungahambi kahle ngenye yezindlela zokusabela kweso lakho, kunganikeza amehlo akho umuzwa wokuthi "kukhona okungahambi kahle," "akulungile neze."

Ngakho-ke, uma ubona noma yiziphi izinguquko emehlweni akho noma ekuboneni, qiniseka ukuthi ubona udokotela wamehlo . Bangahlola amehlo akho kahle futhi bakunike noma yisiphi iseluleko esidingekayo. Khumbula, amehlo ethu ayigugu kakhulu!

Ukusabela kwamehlo , impilo yamehlo, umfundi, i-cornea, umbono, isimiso sezinzwa, ukuhlolwa kwamehlo
