Kev ua kom muaj zog ntawm presynaptic neuron ua rau kev tso tawm ntawm glutamate , uas ces khi rau postsynaptic glutamate ionotropic receptors-NMDA thiab AMPA. Qhov kev hloov pauv no hloov pauv cov yam ntxwv hluav taws xob ntawm lub xov tooj ntawm tes uas ua rau muaj peev xwm ua kom muaj zog postsynaptic.
Xav txog qhov no, dab tsi ua rau tso GABA?
GABA tso tawm Nyob rau hauv lub synaptic cleft yog stimulated los ntawm depolarization ntawm presynaptic neurons. GABA diffuses thoob plaws lub cleft mus rau lub hom phiaj receptors ntawm lub postsynaptic nto. Qhov kev ua ntawm GABA ntawm lub synapse tau xaus los ntawm kev rov ua dua rau ob qho tib si presynaptic cov hlab ntsha thiab ib puag ncig glial cells.
Tsis tas li ntawd, koj yuav txo glutamate li cas? Lithium, nrog rau iodine thiab boron, kuj tuaj yeem pab tau txo glutamate . Kev noj cov calcium hauv cov zaub mov yuav tsum tau txo lossis txwv yog tias calcium ntau dhau. Magnesium kuj tseem tuaj yeem khi thiab qhib GABA receptors.
Ntxiv mus, qhov twg yog glutamate tsim tawm hauv lub hlwb?
Qhov siab tshaj plaws ntawm glutamate muaj nyob rau hauv synaptic vesicles nyob rau hauv cov hlab ntsha terminals los ntawm qhov uas nws yuav tso tawm los ntawm exocytosis. Qhov tseeb, glutamate yog qhov tseem ceeb excitatory neurotransmitter nyob rau hauv mammalian central paj hlwb.
Cov kev mob tshwm sim ntawm GABA yog dab tsi?
Kev mob tshwm sim
- yaug.
- kev nyuaj siab.
- tsaug zog thaum sawv ntxov.
- hluav taws xob poob siab tag nrho lub cev.
- mob siab rau.
- xeev siab.

Dab tsi ua rau tso tawm ADH?
ADH yog tsim los ntawm hypothalamus hauv lub hlwb thiab khaws cia rau hauv cov qog pituitary tom qab ntawm lub hauv paus ntawm lub hlwb. ADH ib txwm tso tawm los ntawm lub caj pas hauv cov lus teb rau cov ntsuas uas pom qhov nce ntawm cov ntshav osmolality (tus naj npawb ntawm cov piam thaj hauv cov ntshav) lossis txo qis hauv cov ntshav
Txoj hauj lwm raug yog dab tsi rau lub raj tso zis tso zis?
Ruaj lub raj xa mus rau koj tus neeg mob lub plab lossis sab ceg qis, tso cai rau qee qhov ua kom qis hauv tubing. Ruaj lub hnab ntim kua rau lub txaj hauv qab nws qib zais zis. Muab kev saib xyuas perineal. Tshem koj lub hnab looj tes thiab ntxuav koj txhais tes
Dab tsi yog CPT cov cai rau tso tawm hauv qab daus?
Txog qhov kev phais mob no, koj yuav saib rau tus lej 25000 (Kev phais mob, txuas txuas txuas ntxiv, lub dab teg (piv txwv li, De Quervains disease)). Yog tias koj tus kws phais mob ua qhov ntau dua radical tenosynovectomy ntawm thawj dorsal compartment, koj tuaj yeem tig mus rau tus lej 25118 (Synovectomy, extensor tendon sheath, dab teg, ib qho chaw)
Dab tsi yog qhov ua rau ua rau lub qhov tso pa tawm Hypercapnic tsis ua haujlwm?
Feem ntau cov ua rau mob hawb pob thiab COPD, overdoses ntawm cov tshuaj uas ua rau lub ventilatory tsav, thiab tej yam kev mob uas ua rau cov leeg ua pa tsis muaj zog (xws li, Guillain-Barré syndrome, myasthenia gravis, botulism)
Dab tsi yog 6 kauj ruam hauv kev tso tawm cov tshuaj xa xov paj hlwb thiab txhua kauj ruam ua dab tsi?
Neurotransmitter tso tawm los ntawm presynaptic davhlau ya nyob twg muaj ib tug series ntawm intricate cov kauj ruam: 1) depolarization ntawm lub davhlau ya nyob twg daim nyias nyias, 2) ua kom muaj voltage-gated Ca2+ channels, 3) Ca2 + nkag, 4) ib tug hloov nyob rau hauv lub conformation ntawm docking proteins, 5) fusion ntawm vesicle mus rau plasma membrane, nrog rau tom qab
