Phunzirani za endorphins ndi zotsatira zawo pa thupi
Endorphins nthawi zambiri amatchedwa kupweteka kwa thupi kwa thupi. Endorphins ndi zinthu zakuthupi zopangidwa ndi thupi lomwe limachepetsa kupweteka ndipo zimabweretsa kumverera kokondwa ndi ubwino.
Chiwerengero cha Endorphins
Endorphins amatchulidwa kuti ndi "opioid polypeptides" otheka kwambiri ndipo amalingaliridwa kuti amapangidwa ndi gland ndi hypothalamus panthawi yochita masewera olimbitsa thupi, komanso chifukwa cha ululu, chisangalalo ndi zovuta zina.
Kamodzi kamatulutsidwa, endorphins imagawidwa mu dongosolo lonse lamanjenje kumene zimagwirizana ndi opiate receptors kuti achepetse kuganiza kwathu kwa ululu. Kupweteka kwachibadwa kumeneku kumachepetsa osati kumangowonjezera kumvetsetsa kwa ululu, koma kumalumikizana ndi kuwonjezeka kwa chisangalalo ndi ubwino.
Mbiri ya Endorphins
Endorphins anapezeka koyamba mu 1974 ndi magulu awiri osiyana a ofufuza enieni. Endorphins anapezedwa pogwiritsira ntchito ndi kuphunzira ubongo wa zinyama. Akatswiri a sayansi John Hughes ndi Hans Kosterliltz, onse a Scotland, endorphins omwe amadziwika kuti ndi omwe amachokera ku ubongo wa nkhumba. Panthawi imodzimodziyo, Rabi Simantou ndi Soloman Snyder, onse awiri a United States, adadziŵa kuti endorphins mu ubongo wa mwana wa ng'ombe. Anapezanso kuti thupi laumunthu, komanso thupi la nyama zambiri, limatha kupanga morphine palokha.
Zotsatira za kafukufuku wosiyanasiyanazi zathandiza akatswiri a sayansi ya zamoyo kudziwa kuti ubongo waumunthu uli ndi endorphins kuti athetse kupweteka, komwe chiwombankhanga chimamasulidwa pamene thupi liri pansi pa kupanikizika kwakukulu, kapena kumva ululu wopweteka.
Mapulogini ameneŵa amagwirizana ndi ovomerezeka kuti athe kuchepetsa kuwona kwa ululu. Zotsatira za ndondomekoyi zimayesedwa, ndipo zimakhala zofanana ndi kugwiritsa ntchito mankhwala monga morphine. Choncho, ngati mankhwala opanga mankhwala monga morphine amalowa m'thupi, mwachiyembekezo ndi dokotala, zimakhudza endorphin.
Izi zimapangitsa kuti vutoli likhale lopweteka kwambiri. Thupi limamvetsa izi, ndipo mobwerezabwereza, kuchepetsa kupweteka kwapweteka kumachitika. Iyi ndi njira yowonetsera ndi thupi. Komabe, pamene gwero lopangidwa lichotsedweratu, zinyama zambiri zopweteka zimakhala zopanda kanthu. Izi zimapangitsa chilakolako cha endorphins, kawirikawiri ngati mankhwala osokoneza bongo, ndipo izi ndizo momwe umwa umayambira.
Wapamwamba Wothamanga
Kwa anthu ena, kuthamanga mtali wautali kwambiri kumayambitsa chisangalalo ndi kumveka kwabwino komwe kumafaniziridwa ndi mkulu woperekedwa ndi mankhwala. Zomwe zimatchulidwa pamtunda wothamanga ndi monga: kumverera kwa mtendere wamtendere, kumverera kwa kuyandama, kukondwa, kukhwima, ndi kupirira kupirira kotere.
Pamwamba pa wothamangayo akuyamikiridwa ndi kuchuluka kwa mapirinphins mu ubongo. Endorphins amamasulidwa nthawi zonse ku thupi ngati munthu akuthamanga ndipo pomalizira pake, kuyambira kwa endorphins mu ubongo kumabweretsa kumverera kwachisangalalo.
