Cov purkinje fibers muaj nyob hauv the sub-endocardium . Lawv loj dua cov leeg mob plawv, tab sis muaj tsawg dua myofibrils myofibrils A myofibril (tseem hu ua cov leeg nqaij fibril lossis sarcostyle) yog ib qho yooj yim qws zoo li lub cev ntawm cov leeg nqaij. Cov leeg yog tsim los ntawm tubular hlwb hu ua myocytes, lub npe hu ua cov leeg nqaij fibers hauv cov leeg nqaij striated, thiab cov hlwb no muaj ntau cov chains ntawm myofibrils. https://en.wikipedia.org › wiki › Myofibril

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.
Puas Purkinje fibers hauv myocardium?
Purkinje fibers yog tshwj xeeb cov kab hluav taws xob myocardialnrog ob peb myofibrils uas txhawb nqa cov kev xa tawm sai ntawm cov impulse los ntawm ventricles. Lawv loj dua li cov myocardial fibers.
Purkinje fibers pom dab tsi hauv plawv?
Purkinje fibers pw hauv deepest txheej ntawm endocardium thiab muab cov leeg papillary.
Purkinje Fibres ua haujlwm yog dab tsi?
Purkinje fibers ua lub luag haujlwm tseem ceeb hauv hluav taws xob conduction thiab nthuav tawm ntawm impulse mus rau cov leeg ventricular. Ntau lub ventricular arrhythmias yog pib nyob rau hauv Purkinje fiber conduction system (eg.
Puas yog Purkinje fibers nyob hauv atria?
Nyobpurkinje fibers nyob rau hauv the atria. Ib qho arrhythmia yog ib qho kev hloov pauv lossis kev sib txawv ntawm tus nqi ib txwm lossis lub plawv dhia.

Ntawm qhov capillaries pom nyob rau hauv lub cev nyob qhov twg?
Nruam: Cov capillaries no tsis muaj perforations thiab cia tsuas yog me me molecules dhau mus. Lawv tam sim no hauv nqaij, tawv nqaij, rog, thiab paj hlwb. Fenestrated: Cov capillaries no muaj cov pores me me uas tso cai rau cov molecules me los ntawm thiab nyob hauv cov hnyuv, ob lub raum, thiab cov qog endocrine.
Postganglionic fibers nyob qhov twg?
postganglionic fiber ntau: Hauv lub paj hlwb autonomic, cov no yog cov fibers uas khiav los ntawm ganglion mus rau lub cev muaj zog. cholinergic: Hais txog, qhib los ntawm, tsim, lossis muaj kev ua haujlwm zoo ib yam li acetylcholine. Postganglionic sympathetic fibers nyob qhov twg?
Cov fibers thiab sclereids nyob qhov twg hauv cov nroj tsuag?
Cov fibers no muaj nyob hauv lub cortex, thiab xylem thiab phloem ntawm cov nroj tsuag. Fibers muab cov neeg kho tshuab kev txhawb nqa. Hom sclereids yog Macro, osteo, Astro, Brachy sclereids. fiber ntau pom nyob rau hauv ib tsob nroj nyob qhov twg?
Pom pom muaj calcium ntau nyob qhov twg?
Calcium yog nyob ib puag ncig peb. Tus tib neeg nruab nrab muaj kwv yees li 1kg ntawm calcium, ntawm 99% khaws cia hauv peb cov pob txha. Nws yog 5th feem ntau cov khoom nyob rau hauv lub ntiaj teb crust, tshwm sim dav li calcium carbonate uas yog feem ntau hu ua limestone.
