Likamano lipakeng tsa Endocrine le Methapo ea Ts'ebetso
Pendahuluan
'Mele oa motho ke mochini o rarahaneng haholo le o kopaneng oa baeloji, moo litsamaiso tse ngata li sebetsang hammoho ho boloka homeostasis, kapa botsitso ba ka hare. Tse peli tsa litsamaiso tsa bohlokoa ka ho fetisisa le tse sebelisanang ke litsamaiso tsa endocrine le methapo. Ka bobeli li bapala karolo ea bohlokoa ho laoleng mesebetsi ea 'mele, ho tloha kholong le nts'etsopele ho ea ho metabolism le karabelo ea khatello ea maikutlo. Sehlooho sena se ikemiselitse ho hlahloba hore na litsamaiso tsena tse peli li sebelisana joang, ho utloisisa mekhoa ea tsona ea puisano, le ho hlahloba mehlala e itseng ea tšebelisano-'moho le tšebelisano-'moho lipakeng tsa litsamaiso tsa endocrine le methapo.
Sistimi ea Endocrine: Selelekela
Sistimi ea endocrine e na le litšoelesa tse hlahisang le ho lokolla lihormone maling. Lihormone tsena li sebetsa e le manģosa a lik'hemik'hale a laolang mesebetsi e fapaneng ea 'mele. Litšoelesa tse kholo tsa endocrine li kenyelletsa pituitary, thyroid, parathyroid, litšoelesa tsa adrenal, manyeme, mae a bomme (ho basali), le li-testes (ho banna). Mehlala ea lihormone tse hlahisoang ke sistimi ea endocrine e kenyelletsa insulin, adrenaline, le lihormone tsa thobalano tse kang estrogen le testosterone.
Tsamaiso ea Methapo: Selelekela
Tsamaiso ea methapo e na le marang-rang a rarahaneng haholo a li-neuron, tse fetisang matšoao a motlakase le a lik'hemik'hale ho pholletsa le 'mele. Tsamaiso ea methapo e ka aroloa likarolo tse peli tse kholo: tsamaiso ea methapo e bohareng (boko le mokokotlo) le tsamaiso ea methapo e ka ntle ho tsamaiso ea methapo e bohareng (methapo eohle e fumanehang ka ntle ho tsamaiso ea methapo e bohareng). Mosebetsi o ka sehloohong oa tsamaiso ea methapo ke ho amohela tlhahisoleseling ea kutlo ho tsoa tikolohong, ho sebetsana le tlhahisoleseling eo, ebe e romela likarabo tse loketseng mesifa le litho tsa 'mele.
Kamano Pakeng tsa Tsamaiso ea Endocrine le ea Methapo
Leha li fapana ka mekhoa ea tsona le mefuta ea melaetsa eo li e romelang (lik'hemik'hale bakeng sa tsamaiso ea endocrine le motlakase bakeng sa tsamaiso ea methapo), litsamaiso tsena tse peli li hokahane haufi-ufi 'me li sebetsa hammoho ho boloka botsitso ba 'mele. Tse ling tsa litsela tseo li sebelisanang ka tsona ke tsena:
1. Hypothalamus le Pituitary: Litsi tsa Khokahano
E 'ngoe ea mehlala e totobetseng ka ho fetisisa ea tšebelisano-'moho lipakeng tsa tsamaiso ea endocrine le methapo ke kamano pakeng tsa hypothalamus le tšoelesa ea pituitary, eo hangata e bitsoang "tšoelesa e kholo." Hypothalamus ke karolo ea boko e hokahanyang tsamaiso ea methapo le endocrine ka tšoelesa ea pituitary. Hypothalamus e hlahisa lihormone tse lokollang le tse thibelang tse susumetsang ts'ebetso ea pituitary. Letšoele la pituitary, le lona, le lokolla lihormone tse laolang ts'ebetso ea litšoelesa tse ling tse fapaneng tsa endocrine 'meleng. Mohlala, hormone ea adrenocorticotropic (ACTH) e hlahisoang ke pituitary e susumetsa litšoelesa tsa adrenal ho hlahisa cortisol, hormone ea bohlokoa karabelong ea khatello ea maikutlo.
2. Karabelo ea Khatello ea Kelello: HPA Axis le Sistimi ea Methapo e Nang le Kutloelo-bohloko
Karabelo ea 'mele khatellong ea maikutlo ke mohlala o mong oa kamoo litsamaiso tsa endocrine le methapo li arolelanang boikarabello kateng. Ha motho a tobane le boemo bo sithabetsang, boko bo bo hlalosa e le tšokelo 'me bo kenya tšebetsong motsoako oa hypothalamic-pituitary-adrenal (HPA). Hypothalamus e lokolla hormone ea corticotropin-releasing (CRH), e ntan'o etsa hore pituitary e lokolle ACTH. ACTH e hlohlelletsa litšoelesa tsa adrenal ho lokolla cortisol, hormone e thusang 'mele ho laola khatello ea maikutlo.
Ka nako e ts'oanang, tsamaiso ea methapo ea kutlo le eona ea sebetsa, e leng se bakang ho lokolloa ha adrenaline ho tsoa ho adrenal medulla. Adrenaline e sebetsa ka potlako ho eketsa sekhahla sa pelo, khatello ea mali le phallo ea mali ea mesifa, e hlomella 'mele ka bokhoni ba ho loana kapa ho baleha.
3. Taolo ea Metabolism: Hypothyroidism le Hyperthyroidism
Tekanyo ea metabolism ea 'mele le eona ke phello ea tšebelisano-'moho lipakeng tsa litsamaiso tsa methapo le tsa endocrine. Mohlala, ho ntšoa ha lihormone tsa thyroid (T3 le T4) ho laoloa ke hormone e susumetsang thyroid (TSH) ho tsoa tšoeleseng ea pituitary, eo ka lehlakoreng le leng e laoloang ke hormone e lokollang thyrotropin (TRH) ho tsoa hypothalamus. Kahoo, taolo ea lihormone tsa thyroid, e susumetsang sekhahla sa metabolism ea 'mele, ke phello ea tšebelisano-'moho lipakeng tsa matšoao a methapo le lihormone.
4. Matšoao a Kutlo le a Lihormone Tšilong ea Lijo
Sistimi ea methapo ea kutlo ea enteric, eo hangata e bitsoang "boko ba bobeli" ba 'mele oa motho, e laola mesebetsi ea tšilo ea lijo ka matšoao a tsoang lihormoneng tsa tšilo ea lijo. Mohlala, lihormone tse kang ghrelin le leptin li phetha karolo ea ho laola takatso ea lijo le tšebeliso ea matla. Ghrelin, e hlahisoang ke mpa, e romela matšoao bokong ho tsosa tlala. Ka lehlakoreng le leng, leptin, e hlahisoang ke lisele tsa mafura (adipocytes), e romela matšoao bokong ho thibela takatso ea lijo le ho eketsa tšebeliso ea matla.
5. Nts'etsopele le Khōlo: Hormone ea Khōlo le Tsamaiso ea Methapo
Kgolo le ntshetsopele ya mmele le tsona ke ditlamorao tsa ho tsamaisana ha endocrine le tsamaiso ya methapo. Hormone ya kgolo (GH), e hlahiswang ke tšoelesa ya pituitary, e laola kgolo ya dinama tsa masapo le mesifa. Ho ntshuwa ha GH ho qalwa ke hormone e lokollang hormone ya kgolo (GHRH) ho tswa ho hypothalamus, e susumetsang pituitary ho hlahisa GH. Ho ntshuwa ha GH ho boetse ho susumetswa ke mabaka a kang boroko, kgatello ya maikutlo le boikoetliso, tseo kaofela di laolwang ke tsamaiso ya methapo.
Mekhoa ea Bongaka le Mathata a Tekanyo
Ho se leka-lekane ha tšebelisano lipakeng tsa litsamaiso tsa endocrine le methapo ho ka lebisa mafung a fapaneng le maemong a bongaka. Mohlala, hypothyroidism (khaello ea hormone ea thyroid) e ka baka matšoao a kang mokhathala, ho nona le ho tepella maikutlong. Ka lehlakoreng le leng, hyperthyroidism (hormone e feteletseng ea thyroid) e ka baka tahlehelo ea boima ba 'mele, matšoenyeho le ho thothomela. Tlhahlobo e nepahetseng le ho kenella ha bongaka, hangata ho kenyelletsang mafapha a mangata, lia hlokahala ho rarolla mathata ana.
Kalafo ea mafu a amanang le tšebelisano ea endocrine le tsamaiso ea methapo hangata e hloka mokhoa o akaretsang o nahanang ka litsamaiso ka bobeli. Meriana ea lihormone, joalo ka thyroxine bakeng sa hypothyroidism, kapa phekolo ea ho nkela lihormone sebaka, e ikemiselitse ho tsosolosa botsitso ba lihormone, ha phekolo ea kelello kapa mekhoa ea taolo ea khatello ea maikutlo e ka thusa ho laola likarolo tsa methapo tsa boemo bona.
Qetello
Tšebelisano pakeng tsa litsamaiso tsa endocrine le methapo ke bopaki ba ho rarahana le botle ba 'mele oa motho. Ka puisano e rarahaneng le e hokahaneng, litsamaiso tsena tse peli li sebetsa 'moho ho boloka botsitso ba 'mele, ho laola mesebetsi ea bohlokoa, le ho arabela maemong a fetohang. Tsebo ea mekhoa ena le likamano tsena ke ea bohlokoa eseng feela bakeng sa kutloisiso ea motheo ea baeloji ea motho empa hape le bakeng sa nts'etsopele ea mekhoa ea bongaka e sebetsang haholoanyane bakeng sa mafu le mathata a fapaneng. Ho khahloa hona ke kamoo 'mele ea rona e sebetsang kateng boemong bo tebileng hakana ho tsoela pele ho susumetsa bo-rasaense le litsebi tsa bongaka ho hlahlobisisa ka botebo le ho batla litsela tse ncha tsa ho ntlafatsa boleng ba bophelo ba motho.
