Mehlala ea Lipotso tse Buisanang ka Sebopeho le Mosebetsi oa Tsamaiso ea Methapo
Tsamaiso ea methapo ke e 'ngoe ea litsamaiso tsa 'mele tse rarahaneng le tsa bohlokoa ka ho fetisisa, e laolang mesebetsi ea bohlokoa joalo ka motsamao, maikutlo le monahano. Ho utloisisa sebopeho le ts'ebetso ea tsamaiso ea methapo hamolemo, ha re buisaneng ka mehlala e latelang.
Pendahuluan
Sistimi ea methapo ea motho e na le likarolo tse peli tse ka sehloohong: tsamaiso ea methapo e bohareng (CNS), e kenyeletsang boko le mokokotlo, le tsamaiso ea methapo e ka ntle, e kenyeletsang methapo e hokahanyang CNS le 'mele oohle. Mosebetsi o ka sehloohong oa tsamaiso ea methapo ke ho amohela lintho tse susumetsang, ho sebetsana le tlhahisoleseling, le ho romela likarabo tse loketseng likarolong tse ling tsa 'mele.
Potso ea 1: Sebopeho sa Motheo sa Li-Neurone
Potso: Hlalosa sebopeho sa neuron le mesebetsi ea eona e fapaneng!
Puisano:
Li-neurone ke diyuniti tsa motheo tsa tsamaiso ya methapo. Neurone ka nngwe e na le dikarolo tse mmalwa tsa bohlokwa:
1. 'Mele oa Sele (Soma): Ena ke setsi sa taolo sa neuron, se nang le khubu ea sele le li-organelle tse ling. Mosebetsi oa eona ke ho sebetsana le tlhahisoleseling e fumanoang ho tsoa ho li-dendrite le ho laola mesebetsi ea metabolism ea neuron.
2. Di-dendrite: Dibopeho tse nang le makala tse atolohang mmeleng wa sele. Di sebetsa ho amohela matshwao a tswang ho di-neuron tse ding le ho a fetisetsa mmeleng wa sele.
3. Axon: Sebopeho se selelele se fetisetsang di-pulse hole le mmele wa sele ho ya ho di-neuron tse ding kapa di-effector tse kang mesifa kapa di-gland.
4. Axon Terminal (Axon End): Sebaka seo ho sona di-impulse tsa motlakase di fetolwang ho ba matshwao a dikhemikhale a tla romelwa ho di-neuron tse ding ka di-synapses.
5. Synapse: Sekgeo se senyenyane pakeng tsa axon terminal le dendrite ya neuron e latelang. Ena ke sebaka seo methapo ya kutlo e fetisetswang ho sona ho tloha neuron e nngwe ho ya ho e nngwe.
Potso ea 2: Litsela tsa Phetiso ea Tšusumetso ea Methapo
Potso: Hlalosa hore na mothapo o feta joang ka har'a neuron ho fihlela o fihla ho neuron e 'ngoe!
Puisano:
1. Phetiso ea Tšusumetso: Methapo ea methapo e qala ho li-dendrite ha li amohela matšoao a lik'hemik'hale ho tsoa ho li-neuron tse haufi kapa ho tsoa linthong tse ka ntle 'me li fetoloa ho ba methapo ea motlakase.
2. Phetiso ka 'Mele oa Sele: Mocheso oa motlakase o fetisetsoa 'meleng oa sele, moo o sebetsoang teng 'me, haeba o le matla ka ho lekaneng, o fetisetsoa ho axon.
3. Phetiso ka Axon: Axon e sebetsa e le tsela ea ho tsamaisa li-pulse tsa motlakase ho tloha 'meleng oa sele ho ea ho axon terminal. Ts'ebetso ena e tsejoa e le phetiso ea li-impulse tsa motlakase kapa bokhoni ba ketso. Li-axon li sirelelitsoe ke lera la myelin, e leng se lumellang phetiso ea li-impulse e potlakileng le e sebetsang hantle.
4. Phetisetso ho Li-Neuron tse Ling: Seteisheneng sa axon, phallo ea motlakase e baka ho lokolloa ha li-neurotransmitter ka har'a synapse. Li-neurotransmitter li tšela lekhalo la synaptic 'me li tlama ho li-receptor tse ho dendrites tsa neuron e latelang, e leng se qalang phallo e ncha ho neuron eo.
Potso ea 3: Sistimi ea Methapo ea Bohareng le ea Pel'a
Potso: Bapisa tsamaiso ea methapo e bohareng le tsamaiso ea methapo e ka ntle ho ea ka sebopeho le ts'ebetso!
Puisano:
– Sistimi ea Methapo e Bohareng (CNS): E entsoe ka boko le mokokotlo. Boko bo laola mesebetsi e fapaneng ea 'mele e kang ho nahana, ho hopola le maikutlo, ha mokokotlo o ikarabella bakeng sa ho fetisa maikutlo pakeng tsa boko le likarolo tse ling tsa 'mele le ho laola maikutlo a' mele.
– Sistimi ea Methapo ea Peripheral (PNS): E na le methapo e hokahanyang CNS le litho tse tšehetsang. PNS e arotsoe likarolo tse peli:
1. Sistimi ea Methapo ea Somatic: E laola motsamao oa mesifa le phetisetso ea tlhahisoleseling ho tsoa ho li-receptor tsa kutlo ho ea ho CNS.
2. Sistimi ea Methapo e Ikemetseng: E laola mesebetsi ea 'mele e sa ikemisetseng joalo ka sekhahla sa pelo le tšilo ea lijo. Sistimi ea methapo e ikemetseng e arotsoe hape ka tsamaiso ea methapo e nang le kutloelo-bohloko (e eketsehang nakong ea khatello ea maikutlo) le tsamaiso ea methapo ea parasympathetic (e khutsisang).
Potso ea 4: Mosebetsi le Karolo ea Lisele tsa Glial
Potso: Phapang ke efe pakeng tsa di-neuron le disele tsa glial, mme mosebetsi wa disele tsa glial ke ofe?
Puisano:
– Li-neurone: Li ikarabella ka ho toba bakeng sa phetiso ea maikutlo a methapo. Joalokaha ho hlalositsoe, li-neurone li entsoe ka li-dendrite, 'mele ea lisele, li-axon le li-synapses.
– Lisele tsa Glial: Lisele tse tšehetsang tsamaisong ea methapo tse sa keneleng phetiso ea methapo empa li bohlokoa bakeng sa ts'ebetso ea methapo. Mesebetsi ea lisele tsa glial e kenyelletsa:
1. Ho Fana ka Phepo le Tšehetso: Ho netefatsa hore li-neurone li fumana phepelo e lekaneng ea oksijene le limatlafatsi.
2. Ho Lahla Litšila tsa Sele: Ho ameha ho lokiseng li-neurone tse senyehileng le ho tlosa litšila liseleng tsa methapo.
3. E Thusa ho Thehoa ha Myelin: E potlakisa phetiso ea methapo ea kutlo ka ho etsa lera la myelin ho potoloha li-axon.
Ho koala
Tsamaiso ea methapo e bapala karolo ea bohlokoa ho tsamaisaneng le taolong ea 'mele, ho tloha mesebetsing ea sensorimotor ho ea mesebetsing ea autonomic. Ho utloisisa sebopeho le ts'ebetso ea tsamaiso ea methapo, ho kenyeletsoa le mesebetsi ea li-neuron le lisele tsa glial, ke senotlolo sa ho notlolla liphiri tsa hore na 'mele ea rona e sebetsa joang. Ka ho buisana ka lipotso tsa mohlala tse kaholimo, re tšepa ho fana ka kutloisiso e hlakileng le e tebileng haholoanyane ea tsamaiso ea methapo.
Re tšepa hore sengoloa sena se tla thusa ho eketsa kutloisiso ea likhopolo tsa motheo tsa tsamaiso ea methapo le ho khothaletsa thahasello e eketsehileng ea ho etsa lipatlisiso tse ling lefapheng la neurobiology.
