Purkinje fibers pw hauv deepest txheej ntawm endocardium thiab muab cov papillary cov leeg papillary Cov leeg papillary yog cov leeg nyob hauv lub ventricles ntawm lub plawvLawv txuas mus rau cusps ntawm atrioventricular li qub (tseem hu ua mitral thiab tricuspid li qub) ntawm chordae tendineae thiab cog lus los tiv thaiv kev thim rov qab los yog prolapse ntawm cov li qub ntawm systole (los yog ventricular contraction). https://en.wikipedia.org › wiki › Papillary_muscle

Nyob rau hauv lub plawv txheej twg yog cov Purkinje fibers pom quizlet?
Lub endocardium muaj cov Purkinje fibers thiab lwm qhov chaw ntawm lub plawv hluav taws xob conduction system.
Purkinje fibers pom nyob qhov twg hauv lub siab?
Cov purkinje fibers muaj nyob hauv sub-endocardiumLawv loj dua li cov leeg mob 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.
Purkinje fibers nyob rau hauv lub plawv nyob qhov twg?
Purkinje fibers (Purkyne cov ntaub so ntswg los yog Subendocardial ceg) nyob hauv cov phab ntsa ventricular ntawm lub plawv, nyob rau hauv qab cov endocardium Cov fibers no tshwj xeeb myocardial fibers uas ua rau hluav taws xob stimulus. los yog impulse uas ua rau lub plawv sib cog lus hauv kev sib koom ua ke.
Purkinje fibers ua haujlwm nyob qhov twg?
Purkinje fibers yog cov xov tooj ntawm fibers uas tau txais cov cim qhia pib ntawm atrioventricular node (AVN), thiab ib txhij qhib sab laug thiab sab xis ventricles los ntawm ncaj qha stimulating lub ventricular myocardium.
