Uropi hwako hunongogadzira chete huremu hwemuviri wako, asi hunoshandisa inopfuura makumi maviri muzana yesimba rako rese remuviri.

Pamwe pamwe nekuve nzvimbo yekufunga kwekuziva, huropi hwako hunodzora mazhinji ezviito zvemuviri wako zvisina basa. Inotaurira magezi ako nguva yekuburitsa mahormone, inodzora kufema kwako, uye inotaurira moyo wako kukurumidza kurova.

Yako medulla oblongata inoumba chete 0,5% yehuremu hwese hwehuropi hwako, asi inoita basa rakakosha mukugadzirisa izvo zvisina basa maitiro. Pasina chikamu chakakosha chehuropi hwako, muviri wako nehuropi zvaisazokwanisa kutaurirana.

Muchikamu chino, tichaongorora kuti medulla oblongata yako iripi uye nekuputsa mabasa ayo mazhinji.

Iko medulla oblongata iri kupi?

Yako medulla oblongata inoita kunge denderedzwa rakatenderedzwa kumagumo ehuropi hwako, kana chikamu chehuropi hwako chinobatana nemuzongoza wako. Iyo zvakare iri pamberi pechikamu chehuropi hwako chinonzi cerebellum.

Cerebellum yako inoita kunge diki huropi hwakabatana kumashure kwehuropi hwako. Muchokwadi, zita rayo rinoshandurwa kuenda ku "huropi hudiki" kubva muchiLatin.

Buri redehenya rako rinoita kuti musana wako wepasipisi upfuure unonzi yako foramen magnum. Yako medulla oblongata inowanikwa padanho rakaenzana kana zvishoma pamusoro peburi iri.

Iyo yepamusoro medulla yako inogadzira pasi pechina ventricle yeuropi yako. Ventricles maburi akazadzwa necebral spinal fluid iyo inobatsira kupa huropi hwako nezvinovaka muviri.

Chii chinoitwa medulla oblongata?

Kunyangwe iri diki saizi, yako medulla oblongata ine akawanda akakosha mabasa. Izvo zvakakosha pakudzosera ruzivo pakati pemutsipa wako wepelinha uye huropi. Iyo zvakare inogadzirisa yako yemoyo uye yemasisitimu ekufema. Amana ako gumi nemaviri anobva kudunhu rino.

Uropi hwako uye musana zvinotaurirana kuburikidza nemakoramu etsinga fibers anomhanya kuburikidza ne medulla yako inonzi spinal mapepa. Aya maturakiti anogona kunge achikwira (tumira ruzivo kuhuropi hwako) kana kuburuka (takura ruzivo kumuzongoza wako).

Imwe yeturakiti rako remuzongoza rinotakura mhando yeruzivo. Semuenzaniso, yako yekupedzisira spinothalamic turakiti inotakura ruzivo rwakanangana nekurwadziwa uye tembiricha.

Kana chikamu chema medulla chako chikakanganisika, zvinogona kutungamira mukusagona kudzorera yakatarwa mhando yemeseji pakati pemuviri wako nehuropi. Mhando dzeruzivo dzakatakurwa nematurakiti aya dzinosanganisira:

• kurwadziwa uye kunzwa
• kubata zvisina kufanira
• kubata kwakanaka
• proprioception
• maonero ekudengenyeka
• maonero ekudzvinyirira
• kuziva kudzora kwetsandanyama
• bharanzi
• mhasuru toni
• kushanda kweziso

Muchinjikwa wako kubva kuruboshwe kuropi hwako kuenda kurudyi rwepelinha yako mu medulla yako. Kana iwe ukakuvadza iro reruboshwe rerutivi medulla yako, zvinotungamira mukurasikirwa kwemota basa kurudyi kwemuviri wako. Saizvozvo, kana kurudyi kwemedulla kukanganisika, zvinokanganisa iro kuruboshwe kwemuviri wako.

Chii chinoitika kana medulla oblongata ikakuvara?

Kana medulla yako ikakuvara, huropi hwako uye musana hazvizokwanise kufambisa ruzivo kune mumwe nemumwe.

Kukuvadza kune medulla oblongata yako kunogona kutungamira ku:

• matambudziko ekufema
• kusagadzikana kwerurimi
• kurutsa
• kurasikirwa kwegag, kuhotsira, kana kukosora reflex
• matambudziko kumedza
• kurasikirwa kwemhasuru kutonga
• kuenzanisa matambudziko
• zvisingadzoreki hiccups
• kurasikirwa kwekunzwa mumakumbo, trunk, kana kumeso

Kune here zvimwe zvirwere zvinokanganisa medulla oblongata?

Mhando dzakasiyana dzezvinetso dzinogona kukura kana medulla yako ikakuvara nekuda kwesitiroko, kushomeka kwehuropi, kana kukuvara musoro kamwe kamwe. Zviratidzo zvinomuka zvinoenderana nechimwe chikamu che medulla yako icho chakakuvara.

Chirwere chePasinson

Chirwere cheParkinson chirwere chinopfuurira chinokanganisa huropi hwako nehurongwa hwetsinga. Zviratidzo zvikuru ndezvi:

• kudengenyeka
• kufamba kunonoka
• kuomarara mumitezo nemu trunk
• kunetseka kuenzanisa

Chikonzero chaicho chePasinson hachisati chazivikanwa, asi mazhinji ezviratidzo anokonzerwa nekudzikisira kwemauron anoburitsa neurotransmitter inonzi dopamine.

Zvinofungidzirwa kuti kudzikira kwehuropi kunotangira pane zvisati zvapararira kune zvimwe zvikamu zvehuropi. Vanhu vane Parkinson vanowanzo kuve nemoyo kusagadzikana kwakadai sekutenderedza kurova kwemoyo yavo uye neropa.

Chidzidzo che2017, chakaitwa pavarwere makumi mashanu nevaviri vane chirwere cheParkinson, chakasimbisa chinongedzo chekutanga pakati pemamulla kusagadzikana neParkinson's. Vakashandisa tekinoroji yeMRI kuti vawane kusagadzikana kwechimiro muzvikamu zve medulla zvine chekuita nematambudziko emwoyo vanhu vane Parkinson vanowanzoona.

Wallenberg chirwere

Wallenberg syndrome inozivikanwa se lateral medullary syndrome. Inowanzo guma nekurohwa padhuze ne medulla. Zviratidzo zvakajairika zveWallenberg syndrome zvinosanganisira:

• kumedza matambudziko
• dzungu
• kusvotwa
• kurutsa
• kuenzanisa matambudziko
• zvisingadzoreki hiccups
• kurasikirwa kwekurwadziwa uye kupisa kwekushisa mukati mehafu yechiso
• chiveve kudivi rimwe remuviri

Dejerine Syndrome

Dejerine syndrome kana medial medullary syndrome chinhu chisingawanzo chinokanganisa isingasviki 1% yevanhu vane sitiroko iyo inobata chikamu chekumashure chehuropi. Zviratidzo zvinosanganisira:

• kushaya simba kweruoko uye gumbo kune rakatarisana nedivi rekukuvara kwehuropi
• rurimi kushaya simba kudivi rimwe rekukuvara kwehuropi
• kurasikirwa kwekunzwa kune yakatarisana nedivi yekukuvara kwehuropi
• kuoma mitezo kune rumwe rutivi rwekukuvara kwehuropi

Bilateral medial medullary syndrome

Bilateral medial medullary syndrome chinhu chisingawanzoitika kubva pakurwara. Chidimbu chete che1% chevanhu vane sitiroko mune yekumashure chikamu chehuropi hwavo ndivo vanokudziridza mamiriro aya. Zviratidzo zvinosanganisira:

• kutadza kufema
• kuoma nhengo dzese dzemakumbo mana
• kusagadzikana kwerurimi

Reinhold chirwere

Reinhold syndrome kana hemimedullary syndrome inonyanya kushomeka. Iko kune chete nezve mune ezvokurapa zvinyorwa zvakagadzira mamiriro aya. Zviratidzo zvinosanganisira:

• kuoma mutezo
• kurasikirwa kwekunzwa kune rumwe rutivi
• kurasikirwa kwemhasuru kudzora kune rimwe divi
• Horner's chirwere
• kurasikirwa kwekunzwa kune rumwe rutivi rwechiso
• kusvotwa
• kuoma kutaura
• kurutsa

Makiyi ekutora

Yako medulla oblongata iri pazasi pehuropi hwako, uko uropi hunobatanidza huropi kumusana wako wepelinha. Inoita basa rakakosha kupfuudza mameseji pakati pesipinha netambo yako. Izvo zvakakoshawo pakugadzirisa yako yemoyo uye masisitimu ekufema.

Kana yako medulla oblongata ikakuvara, inogona kutungamira mukufema kutadza, kuoma mitezo, kana kurasikirwa kwekunzwa.
