Cardiac Organogenesis
Cards in this deck (34)
- 1Blood vessel and heart formation are derived fromHemangioblasts
- 2Vasculogenesis begins in the _ week, in the _ and _3rd week, connecting stalk and extraembryonic mesoderm
- 3The the lateral mesoderm, a horseshoe-shaped aggregation at the anterior end of the embryo is called theCardiac cluster
- 4This central part of the cardiac cluster gives rise to the heartCardiac plate
- 5Growth of existing blood vesselsAngiogenesis
- 6Cardiogenic plate is formed into pairedEndocardial tubes
- 7Endocardial tube forms into 3 layers:Epi, mot, and endocardium
- 83-layered Endocardial tube is contained within the _pericardial cavity
- 9_ brings heart tubes together in future thoracic cavityLateral folding
- 10Fusion and reabsorption of the common wall creates asingle heart chamber
- 11_ folding of the embryonic disk places the heart tube in the thoracic cavityCraniocaudal
- 12The pericardial cavity forms in the _ mesodermLateral
- 13The heart tube is suspended by the _ cranially and the _ caudallyPharangeal arches; Septum transversum
- 14The myocardium thickens with _, and cardiac myocytes and tube forms constrictions and dilationsCardiac jelly
- 15Parts of the embryonic heart, caudal to cranialSinus venous --> Atrium --> Ventricle --> Bulbis cordis --> Truncus arteriosus --> Aortic sac
- 16The heart tube undergoes _ shaped bendingU
- 17Localized proliferation of the endocardium on the dorsal and ventral surface grow toward the midline and fuse, forming theendocardial cushions
- 18Fusion divides the single chamber into two chambers, connected by theleft and right atrioventricular canals
- 19_ and _ grow down from the roof of the atrium and fuse with the endocardial cushions dividing the atria into right/leftSeptum primum and secondum
- 20Blood moves between atria throughForamen ovale
- 21This grows toward the endocardial cushions from the base of the ventricleInterventricular septum (muscular portion)
- 22Extensions of endocardial cushions formMembranous portion of inter ventricular septum
- 23The IV septum contributes to the formation of thePapillary muscles and chordae tendinae
- 24Proliferation of neural crest cells in the wall of the bulbis cordis and truncus arteriosusconotruncal ridges
- 25Septum with a 180 degree spiralAorticopulmonary septum
- 26The aorticopulmonary septum separates the two major vessels of thePulmonary and aortic trunk
- 27Arise from the cardiac sac connecting to dorsal aortaPaired aortic arches
- 28Derivatives of the 3rd archCommon and part of internal carotid arteries
- 29Derivatives of 4th archRight proximal portion of subclavian artery, arch of aorta
- 30Derivatives of 6th archPulmonary arch
- 31Connection between right and left atriaForamen ovale
- 32Shunt between left pulmonary artery and dorsal aortaDuctus arteriosus
- 33Connects umbilical vein to IVC, bypassing the liverDuctus venosus
- 34Changes in fetal vs neonate circulationForamen ovale --> Fossa ovale
Ductus arteriosus --> Ligamentum arteriosus
Ductus venosus --> Ligamentum venosus/teres
