Ese koko uzi iby'aka 'pons' gato mu bwonko bwawe? Reka tubiganireho!

Twese tuvuga ku ngingo nini mu mibiri yacu, sibyo? Nk'umutima, ibihaha, impyiko. Ariko se wigeze utekereza ku kamaro k'uduce duto turi mu bwonko bwacu? Hari igice gito cyane, ariko cy'ingenzi cyane cy'ubwonko bwacu cyitwa 'pons.' Mu magambo make, ni nk'umuntu wicaye mu mitwe yacu akora akazi kenshi bucece.

None se, iyi 'Pons' ni iki?

Mu magambo make, pons zawe ni igice cya kabiri kiva hasi cy'ubwonko bwawe. Mu by'ukuri, ziherereye hejuru gato ya medulla oblongata yawe. Tekereza nk'ikiraro kiri hagati y'ubwonko buri hejuru, medulla oblongata iri hepfo, n'umugongo. Pons ni ihuriro rikomeye ry'imitsi myinshi y'ubwonko bwacu. Imitsi y'ubwonko ni urusobe rw'imitsi ihuza ubwonko neza. Rero, iyi mitsi ni ingenzi cyane. Ifasha mu kumva ibintu byinshi mu mutwe wawe, ndetse no kwimura ibice bitandukanye by'isura yawe n'umunwa.

Ni iki mu by'ukuri Pons ikora? Ni iyihe mirimo yayo y'ingenzi?

"Pons", nk'uko byavuzwe mbere, ni igice cy'ubwonko gihuza ubwonko bwawe n'umugongo. Kubwibyo, "Pons" ni ihuriro ry'ingenzi cyane mu mikorere y'imitsi yawe . Niyo itanga inzira y'amakuru ajya no kuva mu bwonko. By'umwihariko, "Pons" irimo "neurotransmitters" nyinshi zifasha mu mikorere y'ubwonko nko gusinzira.

Reka turebe zimwe mu nshingano z'ingenzi za Pons:

• Igenzura ibitotsi byawe no kuba maso: Tekereza nawe, pons zigira ingaruka zikomeye ku kuntu wumva uhumuye iyo ukangutse mu gitondo, n'uko usinziriye nijoro. Ni nacyo gice gishyiraho urwego rw'umubiri wawe rwo kuba maso iyo ukangutse.
• Icunga ibimenyetso by'ububabare: Pons ifite inshingano zo kohereza ibimenyetso by'ububabare aho ari ho hose mu mubiri wawe munsi y'ijosi ryawe mu bwonko no kugenzura ibyo bimenyetso. Ibi bivuze ko binafasha kumenya ubwoko bw'ububabare wumva.
• Ikorana n'ibindi bice by'ubwonko: Pons ni ihuriro ry'ingenzi n'ikindi gice cy'ingenzi cy'ubwonko cyitwa cerebellum , kigenzura uburinganire n'ingendo z'umubiri wawe. Ikorana kandi n'ibindi bice by'ubwonko, bigenzura guhumeka kwawe.

Tekereza nk'umupolisi wo mu muhanda. Ni weYohereza ibimenyetso mu bwonko , ikongera kwihutisha bimwe muri byo, kandi ikagenzura bimwe muri byo.

Bifitanye isano ite n'imitsi yo mu mutwe?

Pons ifite aho ihurira hakomeye n'imitsi ine muri cumi n'ibiri y'umutwe. Iyi mitsi y'umutwe (tuzayibara dukoresheje imibare y'Abaroma) ihuzwa na Pons:

• Uturemangingo twa Trigeminal (Cranial Never V): Uyu mutsi ni wo utuma mu maso hawe wumva uko ukozeho kandi ubabara. Unagenzura imitsi ukoresha mu guhekenya ibiryo. Urugero, iyo umuntu agukoze ku itama, ukabyumva, cyangwa niba urwaye amenyo, ni ukubera uyu mutsi.
• Abducens nerve (CN VI): Uyu ni umutsi ugenzura imwe mu mitsi ijyana amaso. Iyo uyu mutsi wangiritse, ushobora kubibona nk'ibintu bibiri bitandukanye, twita 'diplopia'.
• Imitsi yo mu maso (CN VII): Iyi mitsi igenzura isura yawe cyane. Iyi mitsi ni yo ikora iyo umwenyuye kandi uhumye. Ni nayo mitsi igufasha kuryoherwa n'ururimi rwawe.
• Umutsi wa Vestibulocochlear (CN VIII): Uyu mutsi ugabanyijemo ibice bibiri: umutsi wa vestibulare n'umutsi wa cochlear.
• Imitsi yo mu nda niyo iguha ubushobozi bwo kuringaniza. Igufasha kuguma uhagaze neza iyo ugenda cyangwa wiruka.
• Umutsi wo mu bwoko bwa cochlear ni wo uguha kumva . Ni ukubera uwo mutsi ushobora kumva indirimbo cyangwa umuntu avuga.

Ni gute pons zifasha izindi ngingo?

Pons zifasha izindi ngingo mu gutwara amakuru y’ibyumviro mu bwonko, kandi zigenzura mu buryo butaziguye zimwe mu nzira umubiri wawe ukoresha mu kutamenya. Urugero, zifasha kugenzura imikorere yawe yo gusinzira no kubyuka ndetse no guhumeka. Ubushobozi bwawe bwo kumva ububabare nabwo bugenzurwa na pons. Ubu bubabare bugufasha gusubiza kugira ngo wirinde cyangwa ugabanye ibyago.

Iyi 'Pons' iri he?

Pons ni imwe mu ngingo zo hasi cyane mu bwonko bwawe, hafi y'ishingiro ry'agahanga kawe. Nkuko byavuzwe mbere, iba hejuru gato ya Medulla Oblongata. Hanyuma Medulla Oblongata ihuza n'umugongo binyuze mu mwobo uri mu nsi y'agahanga kawe.

'Pons' zisa gute? Ni zingana iki?

Ubusanzwe 'Pons' ziba zifite ibara ry'umukara woroshye cyangwa umweru. Mu bijyanye n'imiterere, zisa n'igishishwa cyo hejuru cy'indabyo z'amashu. Mu bijyanye n'ingano:

• Uburebure: Hafi santimetero 27 (1.06 santimetero).
• Ubugari: Hafi santimetero 38 (1.49 santimetero).
• Ubujyakuzimu (ubunini): Hafi santimetero 25.

Reba ukuntu ari nto! Ariko akazi ikora ni kanini.

Inkomoko ya 'Pons' ni iyihe?

Kimwe n'ibindi bice byose by'ubwonko bwawe n'imitsi, pons zigizwe n'ubwoko bwinshi butandukanye bw'uturemangingo tw'imitsi n'imiterere yatwo. Zifite ibice byitwa nuclei ( ubwinshi busobanura nucleus). Nuclei ni amatsinda y'uturemangingo tw'imitsi cyangwa ubwonko dukora umurimo umwe cyangwa tugahuza n'uduce tumwe. Utu turemangingo tugizwe n'ubwoko bubiri bw'ingenzi bw'uturemangingo:

• Uturemangingo (Neurons) : Utu ni uturemangingo tugize ubwonko bwawe n'imitsi, twohereza kandi tugayobora ibimenyetso. Bishobora guhindura ibimenyetso mu buryo bwa chimique cyangwa amashanyarazi.
• Uturemangingo twa Glial: Utu ni uturemangingo tw’inkunga y’imitsi. Nubwo tudatanga ibimenyetso by’imitsi, dufasha uturemangingo tw’imitsi tubikora.

Reka tuvuge byinshi ku ngirabuzimafatizo z'imitsi (Neurons)

Uturemangingo ni uturemangingo twohereza kandi tukakira ibimenyetso by'amashanyarazi n'ibinyabutabire mu mitsi yawe yose. Uturemangingo dufite ibi bice:

• Umubiri w'ingirabuzimafatizo: Iki ni cyo gice cy'ingenzi cy'ingirabuzimafatizo.
• Axon: Iki ni igice kirekire, gisa n'ukuboko gisohoka mu mubiri w'ingirabuzimafatizo. Ku mpera ya axon hari inyongera nyinshi zisa n'intoki, aho ikimenyetso cy'amashanyarazi gituruka kuri neuron gihinduka ikimenyetso cya shimi. Izi nyongera, zitwa synapses, zishobora kohereza ibimenyetso ku zindi ngirabuzimafatizo z'imitsi zegereye. Tekereza axon nk'insinga y'amashanyarazi, naho synapse ikaba nk'agakingirizo kari ku mpera y'insinga.
• Dendrites: Izi ni imiterere mito y'umubiri w'uturemangingo (izina rikomoka ku ijambo ry'ikilatini risobanura "nk'igiti"). Izi dendrites niho ibimenyetso bya chimique biva muri synapses z'izindi neuron zegeranye byakirwa.
• Myelini :Uru ni urwego rworoshye kandi rufite ibinure rukikije axon ya neuron. Kimwe n'icyuma cya pulasitiki gikikije insinga z'amashanyarazi, kirinda axon kandi kigafasha ibimenyetso kugenda vuba.

Imiyoboro y'ubwonko iragoye cyane. Dendrites z'ubwonko bumwe zishobora guhuzwa n'izindi synapses ibihumbi. Utwo tunyangingo tumwe na tumwe ni ture, utundi ni tugufi. Ibi biterwa n'aho turi mu mubiri n'akazi dukora.

Uturemangingo tw’ingirabuzimafatizo (glial cells) ni iki?

Uturemangingo tw’imyakura (twavuga glial-al) dufite imirimo myinshi itandukanye. Dufasha uturemangingo gukura no gukura ukiri muto, kandi tunafasha gucunga uburyo uturemangingo tw’imyakura dukora mu buzima bwawe bwose. Nanone turinda uturemangingo tw’imyakura kwandura, tugenzura uburyo uturemangingo tw’imyakura dukora, kandi tugakora sheath ya myelin ikikije axons zawe. Igitangaje ni uko hari uturemangingo tw’imyakura twikubye inshuro icumi ugereranije n’uturemangingo tw’imyakura mu buryo bw’imyakura yawe! Ni nk’itsinda ry’imashini zikora imodoka zisiganwa ku magare (neurons).

Ni izihe ndwara zikunze kugira ingaruka kuri Pons?
