Nyob rau hauv lub paj hlwb peripheral, s altatory conduction yog ua tau los ntawm a series ntawm morphologically thiab molecularly txawv subdomains nyob rau hauv ob qho tib si axons thiab lawv txuam myelinating Schwann hlwb.

Yuav ua li cas ua rau s altatory conduction tau quizlet?

txheej txheem los ntawm uas yog tias insulating myelin nyob rau ntawm ib qho axon ces cov hlab ntsha impulses uas tau ua yuav "dhia" los ntawm qhov sib txawv mus rau qhov sib txawv hauv txheej myelin. S alta in spanish=dhia.

Dab tsi ua rau s altatory conduction?

Cov teeb liab hluav taws xob mus nrawm dua hauv axons uas tau thaiv nrog myelin. … Txoj kev muaj peev xwm taug kev hauv axon "dhia" ntawm node mus rau ntawm. Qhov no yog hu ua s altatory conduction uas txhais tau tias "leap." S altatory conduction yog txoj hauv kev nrawm dua rau kev taug kev hauv axon dua li taug kev hauv axon yam tsis muaj myelin.

Yuav ua li cas ntsev ntsev yuav tshwm sim nyob qhov twg?

Kev faib tawm. S altatory conduction tshwm sim nyob rau hauv cov paj hlwb myelinated ntawm vertebrates, tab sis tom qab tau pom nyob rau hauv ib khub ntawm medial myelinated giant fibers ntawm Fenneropenaeus chinensis thiab Marsupenaeus japonicus cws, nrog rau hauv nruab nrab loj fibers. ntawm ib tug earthworm.

Vim li cas kev ua ntsev ntsev tseem ceeb?

S altatory conduction muab ob qhov txiaj ntsig ntawm kev coj ua uas tshwm sim raws li axon yam tsis muaj myelin sheaths. Ua ntej, nws txuag lub zog los ntawm kev txo qis kev siv sodium-potassium twj tso kua mis hauv axonal membrane. Thib ob, qhov nce nrawm tau them los ntawm hom kev coj ua no tso cai rau lub cev tuaj yeem hnov qab thiab xav nrawm dua
