Junctional folds yog qhov tshwj xeeb rau kev sib tshuam neuromuscular, nce kev ntseeg tau ntawm kev sib kis los ntawm kev ua haujlwm ntawm acetylcholine receptors rau lub crests ntawm cov quav thiab txhim kho cov nyhuv ntawm depolarisation los ntawm localization ntawm sodium channels hauv troughs.
Dab tsi yog kev sib txuas folds?
Kev sib tw folds. - Folds uas form hauv cov leeg nqaij daim nyias nyias. - Cov folds junctional yog nyob rau hauv qab ntawm thaj chaw nquag ntawm lub paj hlwb ntawm NMJ.
Tus qauv thiab kev ua haujlwm ntawm cov hlab ntsha neuromuscular yog dab tsi?
Neuromuscular junction yog a microstructure tam sim no ntawm kev sib tshuam ntawm lub cev muaj zog neurons thiab cov leeg nqaij pob txha. Nws ua raws li tus choj txuas rau lub cev pob txha thiab lub paj hlwb. Lub neuromuscular hlws ris yog ib qho tshuaj synapse. lub cev muaj zog neuron muaj cov synaptic vesicles.
junctional folds nyob qhov twg?
Lub cev muaj zog kawg-phaj muaj folds hauv the sarcolemma, hu ua junctional folds, uas tsim ib cheeb tsam loj rau cov neurotransmitter khi rau receptors. Feem ntau, muaj ntau qhov folds thiab invaginations uas ua rau thaj chaw saum npoo av suav nrog kev sib txuas ntawm lub tshuab kawg ntawm lub tshuab kawg thiab T-tubules thoob plaws hauv lub hlwb.
Dab tsi yog qhov ua haujlwm ntawm neuromuscular junction?
Lub neuromuscular hlws ris (NMJ) yog qhov siab heevTshwj xeeb synapse ntawm lub cev muaj zog neuron paj hlwb davhlau ya nyob twg thiab nws cov leeg nqaij fibers uas yog lub luag haujlwm rau hloov hluav taws xob impulses tsim los ntawm lub cev muaj zog neuron rau hauv hluav taws xob ua haujlwm hauv cov leeg nqaij.
