Vesicles fuse nrog presynaptic membrane thiab tso lawv cov ntsiab lus mus rau hauv lub synaptic cleft (exocytosis). … Ib qho axon davhlau ya nyob twg ntawm ib qho kev sib txuas neuromuscular feem ntau tso tawm ob peb puas ntawm nws ntau txhiab tus synaptic vesicles nyob rau hauv ib qho lus teb rau ib qho kev ua tau zoo.
Dab tsi yog qhov synaptic vesicles ntawm cov hlab ntsha neuromuscular hlws ris muaj?
Thaum muaj kev sib tshuam ntawm cov neuromuscular, lub davhlau ya nyob twg presynaptic yog lub davhlau ya nyob twg axonal ntawm lub cev muaj zog neuron. Lub axonal davhlau ya nyob twg muaj ib tug xov tooj ntawm synaptic vesicles. Cov vesicles no muaj cov neurotransmittersuas tau tso tawm thaum tau txais lub paj hlwb. Lub davhlau ya nyob twg presynaptic kuj muaj calcium channels.
Yuav ua li cas tso tawm ntawm neuromuscular synapse?
Nyob rau ntawm qhov sib txuas neuromuscular, cov paj hlwb muaj peev xwm xa cov teeb liab mus rau cov leeg nqaij fiber ntau los ntawm kev tso tawm ACh (thiab lwm yam), ua rau cov leeg nqaij.
Yuav ua li cas yog qhov kev txiav txim ntawm cov xwm txheej ntawm cov kab mob neuromuscular hlws ris?
Yog tias qhov depolarization nce mus txog qhov pib, qhov kev ua haujlwm yuav raug tsim tawm hauv cov leeg nqaij, uas yuav ua rau cov leeg nqaij. Yog li, tus lej ua ntu zus, uas muab qhov tseeb ntawm cov xwm txheej ntawm cov kab mob neuromuscular yog (6), (2), (1), (4), (3), (5).
Dab tsi yog qhov tseem ceeb neurotransmitter tso tawm ntawm qhov sib txuas neuromuscular?
Acetylcholine (ACh) yog tus thawj cojneurotransmitter ntawm vertebrate neuromuscular hlws ris (NMJ), txawm li cas los xij txij li kev tshawb pom tias motoneurons thiab presynaptic terminals ntawm nas endplates los ntawm cov leeg hindlimb extensor digitorum longus (EDL) thiab soleus yog qhov zoo rau glutamate labeling [1, 2], nws tau …
