Curare cuam tshuam rau qhov stimulus (EPSP) uas ib txwm ua rau qhov pib ntawm cov leeg nqaij muaj peev xwm Tus tsiaj uas raug tshuaj lom nrog curare yuav asphyxiate vim tias cov txheej txheem ntawm neuromuscular kis mus rau neuromuscular kis tau tus mob neuromuscular hlws ris (los yog myoneural junction) yog tshuaj synapse ntawm lub cev muaj zog neuron thiab cov leeg nqaijNws tso cai rau lub cev muaj zog neuron xa cov teeb liab mus rau cov leeg nqaij, ua rau cov leeg mob. Cov leeg yuav tsum tau innervation rau kev ua haujlwm-thiab txawm tias tsuas yog tswj cov leeg nqaij, tsis txhob atrophy. https://en.wikipedia.org › wiki › Neuromuscular_junction

ntawm cov leeg ua pa yog thaiv. Nquag, qhov loj ntawm cov phaj kawg muaj peev xwm loj heev.
Qhov txiaj ntsig ntawm curare yog dab tsi?
Curare ua raws li tus neeg saib xyuas neuromuscular thaiv los ntawm kev khi rau acetylcholine receptor (AChR) ntawm qhov sib txuas neuromuscular thiab tiv thaiv cov paj hlwb los ntawm kev ua kom cov leeg pob txha (Bowman, 2006).
curare cuam tshuam dab tsi ntawm cov leeg nqaij daim ntawv xeem?
Curare ua rau cov acetylcholine receptors ntawm lub cev lub cev ntawm cov leeg. Nws ua li ntawd los ntawm kev thaiv cov nicotinic acetylcholine receptors.
Dab tsi ua rau cov leeg nqaij muaj peev xwm ua tau?
Ua kom nAChR ua rau kev nkag mus ntawm cations (sodium thiab calcium) uas ua rau depolarization ntawm cov leeg nqaij daim nyias nyias. Qhov no depolarization nyob rau hauv lem activates ib tug siab ceev ntawm voltage-gated sodium raws ntawm cov leeg nqaij daim nyias nyias, eliciting muaj peev xwm ua.
Dab tsi yog qhov txawv ntawm qhov kawg phaj muaj peev xwm thiab qhov ua tau zoo?
End-phaj peev xwm (EPP), tshuaj lom neeg hloov pauv hauv lub peev xwm hluav taws xob ntawm lub tshuab kawg phaj, feem ntawm cov leeg-hlwb daim nyias nyias uas nyob sab nraud ntawm lub davhlau ya nyob twg ntawm cov hlab ntsha ntawm cov hlab ntsha neuromuscular.… Cov peev xwm ua tau yuav ua rau cov leeg nqaij cell kom cog lus

Thaum qhov xwm txheej wavelength yog lambda txwv tsis pub muaj peev xwm?
Thaum qhov xwm txheej wavelength yog lamda, nres muaj peev xwm yog 3V_0 . Kev sib raug zoo ntawm kev txwv tsis pub muaj peev xwm thiab wavelength yog dab tsi? Given: Stopping potential=V s =2 V , wavelength of events light=λ=2000 Å=2000 x 10 - 10 m, ceev lub teeb=c=3 x 10 8 m/s, Planck's tas li=h=6.
Nyob hauv kev muaj peev xwm lossis muaj peev xwm?
Tsis muaj lo lus hability. Muaj peev xwm muaj kev paub, kev txawj ua ib yam dab tsi. Lo lus ze tshaj plaws rau kev noj qab haus huv yuav yog qhov qub, tab sis ib txwm peb tsuas yog hais tias nws nyob tau lossis nyob tsis tau. Feem ntau yog xa mus rau ib puag ncig lossis tsev .
Puas miv purrs puas muaj peev xwm kho tau?
Purring tso endorphins hauv miv, thiab nws tuaj yeem ua tau tib yam hauv tib neeg, ib yam nkaus. Cov tshuaj hormones uas txo qis kev ntxhov siab muaj txiaj ntsig zoo rau kev kho mob, txo cov ntshav siab, thiab pab tib neeg tiv thaiv kab mob, thiab.
Rau qhov xwm txheej ua rau tus neeg ua haujlwm tsis muaj peev xwm tshaj xya hnub?
Ntau tshaj xya-hnub tsis muaj peev xwm ntawm tus neeg ua haujlwm Cov xwm txheej yuav tsum tau tshaj tawm qhov uas lawv ua rau tus neeg ua haujlwm lossis tus neeg ua haujlwm tus kheej nyob deb ntawm kev ua haujlwm, lossis tsis tuaj yeem ua lawv txoj haujlwm ib txwm ua, ntau tshaj xya lub sijhawmhnub vim lawv raug mob.
