Purkinje fibers yog cov tes hauj lwm ntawm fibers uas tau txais cov cim hluav taws xob los ntawm lub atrioventricular node atrioventricular node Lub atrioventricular node los yog AV node yog ib feem ntawm cov hluav taws xob conduction system ntawm lub plawv uas coordinates saum lub plawv. Nws hluav taws xob txuas lub atria thiab ventricles. https://en.wikipedia.org › wiki › Atrioventricular_node

(AVN), thiab ib txhij qhib sab laug thiab sab xis ventricles los ntawm ncaj qha stimulating lub ventricular myocardium.

Purkinje fibers muaj nuj nqi dab tsi?

Lawv ua lub luag haujlwm ntawm lub plawv muaj peev xwm sai dua thiab ua tau zoo dua li lwm lub hlwb hauv plawv. Purkinje fibers tso cai rau lub plawv txoj kab ke los tsim kev sib koom ua ke ntawm nws cov ventricles, thiab yog qhov tseem ceeb rau kev tswj lub plawv zoo ib yam.

Purkinje Fibers nyob qhov twg?

Cov purkinje fibers muaj nyob rau hauv sub-endocardium. Lawv loj dua cov hlab plawv, tab sis muaj tsawg dua myofibrils, ntau glycogen thiab mitochondria, thiab tsis muaj T-tubules. Cov hlwb no txuas nrog ua ke los ntawm desmosomes thiab qhov sib txawv junctions, tab sis tsis yog los ntawm intercalated discs.
