Kuyang'anitsitsa kwambiri Chiyambi cha Mutu wamutu
N'chifukwa chiyani mutu wa maselo amatchedwa alarm clock mutu? N'chifukwa chiyani mitu imeneyi imapezeka usiku?
Nthano imodzi ndi yakuti mutu wamagulu umachokera ku hypothalamus - woyang'anira kugona kwa munthu ndi chizungulire cha circadian.
Tiyeni tione chiphunzitso ichi pang'ono.
Nchifukwa chiyani Mutu wamutu wa Cluster umatchedwa Mutu wa Kumutu?
Masewera amtunduwu amayamba usiku, pafupi ndi maola awiri kapena awiri munthu atagona.
Amakhalanso nthawi yomweyo tsiku ndi tsiku kapena usiku uliwonse, ndipo nthawi zambiri amatha kubwerera nthawi yomweyo.
Ichi ndichifukwa chake mitu ya masana imatchedwa kuti ola la mutu, chifukwa zimakonda kuchitika pa nthawi yapadera, monga nthawi.
Popeza kuti masoka ambiri a masango amayamba usiku, asayansi amakhulupirira kuti mwina hypothalamus (nthawi yanu yokhayokha) imakhudzidwa ndi chiyambi chake.
Kodi Hypothalamus ndi chiyani?
The hypothalamus ndi dongosolo lomwe lili pansi pa ubongo. Imatumikira maudindo ambiri kuphatikizapo:
- kuyang'anira dongosolo lanu la endocrine (hormone)
- kukhazikitsa dongosolo lanu la autonomic
- ndikuyendetsa kugona kwanu.
"Masango" a maselo a mitsempha mu hypothalamus omwe amadziwika kuti "coreraasastic" (SCN) amatumikira monga mbuye wa circadian-kutanthauzira kutalika kwa usana ndi usiku pogwiritsa ntchito chidziwitso kwa maso athu. SCN imatumiza mauthenga kumbali ina ya ubongo, yotchedwa pineal gland-kachilombo kakang'ono mu ubongo kamatulutsa homoni yotchedwa melatonin .
Kutulutsidwa kwa melatonin ndikutalika usiku usana ndi wotsika masana pamene kuwala kutuluka. Melatonin amachitapo kanthu muzokambirana zovuta kumbuyo kwa hypothalamus.
The hypothalamus imathandizanso kutumiza zizindikiro pambali pa nkhope yanu yomwe mumamva ululu.
Kugwiritsa ntchito mitsempha imeneyi kumatchedwa trigeminal-autonomic reflex-sayansi yodzikongoletsera ya mitsempha yodabwitsa kwambiri yomwe imatumiza uthenga wowawa ku ubongo.
Kodi The Hypothalamus Theory Inathandizidwa ndi Sayansi?
Pali maphunziro a sayansi omwe amathandiza udindo wa hypothalamus, makamaka chipangizo cha suprachiasmatic (SCN), mu masewera a masana. Mwachitsanzo, zapezeka kuti kusungunuka kwa melatonin usiku kumakhala kochepa kwambiri kapena kuponderezedwa panthawi ya masoka (pamene iyenera kukhala yapamwamba). Kumbukirani, melatonin imadyetsa ku hypothalamus.
Izi zikunenedwa, pamene nthawi zina melatonin imagwiritsidwa ntchito popeweratu mutu wa masana, palinso zochepa zofufuza za sayansi kuti zitsimikizire ntchito yake.
Komabe, zowonjezereka kwambiri, kuti kafukufuku wa neuroimaging apeza kuti hypothalamus imakhala yopanda mphamvu panthawi ya kupweteka kwa mutu, ndipo pamene hypothalamus imayesedwa (monga momwe zimakhalira m'maganizo mwakuya), masewera a masango amachepetsedwa.
Kuchulukitsa ubongo wa hypothalamus pakalipano kwasungidwa kwa anthu omwe ali ndi mutu wamagulu osawuka omwe sanalandire chithandizo ndi mankhwala ena (monga oxygen kapena triptan mankhwala). Ichi ndi chifukwa chakuti ndi opaleshoni ndipo ikhoza kuyambitsa magazi mu ubongo, omwe angathe kupha.
Mfundo yayikulu apa ndi yakuti pamene chiyambi chenicheni cha mutu wa masango sichidziwikiratu, mwina chimakhala ndi hypothalamus.
Malinga ndi chidziwitso chimenecho, mankhwala okhudzana ndi hypothalamus monga oyang'anira mutu wa mutu ayenera kupitilizidwanso.
Mawu Ochokera
Ngati mukuvutika ndi ululu wa masango, mukhoza kulingalira za kugona kwanu ndi katswiri wanu wa m'maganizo kapena katswiri wa mutu kuti muzindikire momwe chizunguliro chanu ndi zowawa za mutu zimagwirizanitsidwa.
