Kiki ekyandituuse ku mubiri gwo singa embwa ekugoba mu bwangu ng’otambula ku luguudo, oba singa osimattuka akabenje akanene mu bufunda mu kiseera ky’otosuubira? Teebereza... omutima gwo gukuba mangu, otuuyana, okussa kwo kweyongera, amaaso go ne gazibuka, nedda? Leero tugenda kwogera ku nkola eyeewuunyisa munda mu mubiri gwaffe eteekateeka omubiri gwaffe mu mbeera ez’amangu, ez’akabi, oba embeera ezitunyigiriza, era n’etuwa amaanyi okwolekagana n’embeera oba okudduka (Fight-or-Flight). Ekyo kye tuyita Sympathetic Nervous System (SNS) .
Mu ngeri ennyangu, ensengekera y’obusimu obuyitibwa Sympathetic Nervous System (SNS) kye ki?
Kino kiyinza okuwulikika ng’erinnya erizibu, naye mu butuufu lyangu nnyo. Enkola yo ey’obusimu obusaasizi (SNS) kitundu ku nkola yo ey’obusimu obuyitibwa Autonomic Nervous System. Tuyinza n'okugiyita enkola y'obusimu "ekola otomatiki". Ekyo kiri bwe kityo kubanga kifuga ebintu bingi ebibaawo mu mibiri gyaffe bye tutafuga mu kumanya.
Teebereza, tosobola kufuga bintu ng’okukuba kw’omutima, puleesa, okugaaya emmere, okufulumya omusulo n’okutuuyana. Ebintu ebyo byonna bibaawo mu ngeri ey’otoma. SNS eno kitundu ku nkola enkulu efuga ebintu ng’ebyo.
Naye SNS emanyiddwa nnyo olw’okuddamu embeera ez’akabi oba ezitunyigiriza , nga bwe twayogeddeko emabegako. Mu biseera nga bino, SNS yo eyingira n’eteekateeka buli kimu ekiri munda mu mubiri gwo okukutaasa akabi ako.
SNS eno ekola etya mu biseera eby’akabi?
SNS efuga okuddamu kwaffe okwa "Fight-or-Flight". Kwe kugamba, okuteekateeka omubiri "okulwana oba okudduka." Bw’owulira akabi oba situleesi ey’amaanyi, SNS ekola era n’ekola enkyukakyuka zino nnyingi mu mubiri gwo.
| Ekitundu ky’omubiri | Enkyukakyuka ebaawo n’ekigiviirako |
|---|---|
| Amaaso | Omusota gw’eriiso gugaziwa. Kino kisobozesa ekitangaala ekisingawo okuyingira mu liiso, ne kisongoza okulaba n’okukuyamba okulaba obulungi ebikwetoolodde. |
| Omutima | Kyongera ku kukuba kw’omutima, ogusindika amangu omusaayi ogulimu omukka gwa oxygen okutuuka mu binywa n’ebitundu ebirala, ne gukuwa amaanyi okudduka oba okulwana. |
| Amawuggwe | Ebinywa by’emikutu gy’empewo biwummulamu, ne kisobozesa omukka omungi okuyingira mu mawuggwe. |
| Enkola y’okugaaya emmere | Kiyimiriza okugaaya emmere okumala akaseera oba okukola okusiiba ennyo. Kikekkereza amaanyi agaali gagenda mu kugaaya emmere era n’alungamya amaanyi ago we gasinga okwetaagisa mu kiseera ekyo, ng’ebinywa. |
| Ekibumba | Amasoboza (ssukaali/glucose) agaterekeddwa mu kibumba gafuluma mangu mu musaayi. Kino kiwa omubiri amaanyi agasobola okukozesebwa amangu ddala. |
Enkyukakyuka zino zonna bwe zigattibwa wamu, zikuyamba okulowooza amangu, okukola amangu, n’okwongera amaanyi, okugumiikiriza, n’okulowooza. SNS eno era ekola ng’owulira ng’olina situleesi, gamba ng’okola dduyiro oba ng’oli mulwadde.
Ekisinga obukulu, SNS eno era ekosa abaserikale baffe abaserikale n’enkola y’omubiri ey’okuwona ebiwundu. Kino kitegeeza nti singa obuvune bubaawo mu kabenje, kiyamba okutandika enkola eyeetaagisa okubuwona amangu.
Ababaka ba kemiko abatambuza obubaka (Neurotransmitters) .
SNS eno ekozesa eddagala ery’enjawulo eriyitibwa neurotransmitters okuweereza obubaka mu mubiri gwonna. Okusingira ddala, ekozesa ababaka b’eddagala abayitibwa norepinephrine, epinephrine (era emanyiddwa nga adrenaline), ne acetylcholine .
Njawulo ki eriwo wakati w’enkola ya Sympathetic ne Parasympathetic?
Kino kinyuma nnyo. Obusimu bwo obwa Sympathetic (SNS) ne Parasympathetic bulinga enjuyi bbiri ez’ekinusu. Zikola mu makubo agatali gamu ddala .
- Enkola y'okusaasira (SNS): Etwala obubonero obu "alabula" omubiri n'okuguteekateeka okulwana. Nga accelerator mu mmotoka.
- Enkola ya parasympathetic:Kitambuza obubonero obu "buwummuza" omubiri ne guguzza mu mbeera eya bulijjo. Nga buleeki ku mmotoka bwe ziri.
Enkola zino zombi zikolagana okukuuma emibiri gyaffe nga gikwatagana. SNS y’ekulembera okutuusa ng’akabi kawedde. Obulabe bwe bumala, enkola ya Parasympathetic ekwata ekifo, n’ezza ebintu ng’omutima ogudduka n’okussa amangu mu mbeera eya bulijjo, n’okukkakkanya omubiri. Kino tukiyita "Kuwummula n'okugaaya."
Embeera ki ez’obujjanjabi ezikosa enkola eno eya SNS?
Ebyembi, enkola eno enkulu era esobola okukosebwa endwadde n’ebizibu eby’enjawulo. Ka tulabe ebitonotono ku byo.
| Embeera y’obujjanjabi | Ennyinyonnyola ennyangu |
|---|---|
| Ssukaali ow’ekika eky’okubiri | Ssukaali bw’atafugibwa obubi asobola okuleeta obusimu okwonooneka. Ekyokulabirako ye puleesa okukka amangu ng’oyimiridde (orthostatic hypotension). |
| Okweraliikirira n’okunyigirizibwa okutambula obutasalako | Bw’oba weeraliikirira oba ng’olina situleesi buli kiseera, SNS yo ebeera ng’ekola buli kiseera. Kino kiyinza okuvaako ebizibu ebirala, gamba ng’omugejjo, okumala ekiseera. |
| Kookolo | Pheochromocytoma, ekika kya kookolo ekikula mu nseke z’ekibumba waggulu w’ensigo, asobola okuleetera SNS okukola ennyo, ekivaako okufulumya ekisusse ekirungo kya adrenaline ne norepinephrine. |
| Obulwadde bwa Horner | Kino kikosa enkolagana ya SNS mu maaso. Obubonero buno mulimu akatundu akatono ku ludda olumu olw’eriiso, obutatuuyana ku ludda olwo, n’ebikowe by’amaaso okugwa. |
| Yinfekisoni | Akawuka ne bakitiriya ebimu bisobola okwonoona obusimu. |
| Okukosebwa | Okusingira ddala obuvune ku mugongo busobola okuleeta okwonooneka okw’olubeerera ku biyungo bya SNS. |
| Obutakola bulungi mu by’okwegatta | Okwonooneka kwa SNS kuyinza okuvaako abasajja okufuna okusituka okuluma okumala essaawa ezisukka mu 4 (priapism). Singa kino tekijjanjabwa, kiyinza okuvaako omuntu obutafuna maanyi ga lubeerera. |
Bubonero ki obuyinza okuva mu buzibu ku nkola ya SNS?
Singa wabaawo obuzibu ku nkola eno, obubonero obw’enjawulo busobola okulabika. Bw’oba olina ekimu oba ebisingawo ku bino, kikulu nnyo okulaba omusawo akuwe amagezi .
- Obutabeera bulungi mu kukuba kw’omutima (Arrhythmias) .
- Obuteeyabya
- Okuziyira oba okuziyira ng’oyimiridde
- Ekibikka ky’amaaso ekigwa (Ptosis) .
- Omutima okukuba amangu awatali nsonga, ne bwe kiba nga kiyimiridde buyimiridde (Tachycardia) .
- Obutakola bulungi mu kwegatta (e.g., priapism) .
- Okutuuyana ennyo (Hyperhidrosis) oba obutatuuyana (Anhidrosis) .
- Obuzibu mu kugaaya emmere (Gastroparesis) .
- Okukaluubirirwa okumira emmere (Dysphagia) .
Bikebe ki ebikolebwa okuzuula ebizibu bino?
Omusawo ayinza okukuwa amagezi okukebera ekimu oba ebisingawo ku bino okusinziira ku bubonero bwo.
- Okukebera omusaayi: Zisobola okuzuula ebintu bingi, gamba ng’obuzibu bw’abaserikale b’omubiri n’emiwendo gy’obusimu obutambuza obusimu.
- Okupima puleesa: Puleesa epimibwa mu bifo eby’enjawulo (nga bayimiridde, nga bagalamidde).
- Electrocardiogram (EKG): Okukebera omulimu gw’omutima.
- MRI scan (Magnetic Resonance Imaging): Okukebera ensengekera y’obusimu.
- Okukebera obusimu obuyitibwa autonomic nervous system testing: Ebigezo ebiddiriŋŋana ebikebera obusobozi bw’okufuga okukuba kw’omutima, puleesa n’okutuuyana.
Okwewala otya embeera zino?
Wadde nga tetusobola kuziyiza mbeera ezimu ezikosa enkola ya SNS (e.g. endwadde z’obuzaale), tusobola okuziyiza oba okulwawo ebizibu bingi nga tukyusa obulamu bwaffe.
- Lya emmere ennungi: Obutaba na vitamiini naddala Vitamiini B12 kiyinza okukosa obusimu. Ekirala, okumira ennyo vitamiini (naddala B6) kya bulabe.
- Weewale ebiragalalagala n’omwenge: Bino bya butwa eri obusimu.
- Sigala ng’okola emirimu gy’omubiri n’okukuuma obuzito obulungi: Okuziyiza oba okulwawo obulwadde bwa sukaali obw’ekika eky’okubiri kiyinza okukendeeza ku bulabe bw’okwonooneka kw’obusimu.
- Yambala ebyuma ebikuuma bwe kiba kyetaagisa: Kino kiyamba okuziyiza obusimu okwonooneka olw’obubenje ku mulimu oba ng’ozannya emizannyo.
- Dukanya bulungi embeera ezitawona: Bw’oba olina embeera nga sukaali oba puleesa, okugoberera ebiragiro by’omusawo kijja kukuyamba nnyo mu kukuuma obusimu bwo.
Mu nkomerero, Sympathetic Nervous System (SNS) ye mukuumi w’omubiri gwaffe yennyini, eyeetaagisa ennyo mu bulamu bwaffe n’okutukuuma mu mbeera ezituleetera okunyigirizibwa. N’olwekyo, okulabirira obulungi enkola eno n’obusimu bwonna kijja kutuyamba nnyo okubeera n’obulamu obulungi, obuwanvu.
Obubaka Obutwala Awaka
- Enkola ya Sympathetic Nervous System (SNS) ye nkola y'omubiri gwaffe eya "Fight-or-Flight" ekola mu biseera eby'akabi oba situleesi.
- Enkola eno eteekateeka omubiri okwolekagana n’embeera eno ng’ekola enkyukakyuka ng’omutima okukuba amangu, okutuuyana, n’okulaba obulungi.
- Enkola eno, awamu n'enkola ya Parasympathetic, "ewummuza" omubiri, ekuuma bbalansi mu mubiri.
- Embeera nga ssukaali, situleesi etawona, n’obulwadde obumu bisobola okukosa enkola y’enkola eno.
- Bw’ofuna obubonero ng’omutima okweyongera mu ngeri etategeerekeka, okutuuyana ennyo, oba okuziyira, tobuusa maaso era weebuuze mangu omusawo akuwe amagezi .
- Enkola ya SNS esobola okukuumibwa nga ogoberera obulamu obulungi n’okuddukanya obulungi endwadde ezitawona.
