Heart Development
Derivatives
Lateral plate mesoderm
Splanchnic mesoderm
Endocardial tubes
Endocardium
Epicardium
Myocardium
Vitelline veins
Sinusoids in liver
Sinus venosus
Left sinus venosum
Coronary sinus
Right sinus venosus
Right atrium
Sinus venarum
Primitive Atrium
Auricles
Primitive ventricle
Left ventricle
Bulbus cordis
Middle: Infundibulum
Superior: truncus arteriosis
Inferior: right ventricle
Aortic sac
Aortic root/ascending aorta
Umbilical vein
Ductus venosum
IVC
Common cardinal veins
Brachiocephaic veins
Primitive Heart Tube Development
Organization
Sinus venosum
Where common cardinal, vitelline, and umbilical veins drain
Primitive atrium
Primitive ventricle
Bulbis cordis
Truncus arteriosis
Circulation
Heart ouput
Umbillical arteries
Vitelline arteries
Aorta
Aortic arches (6)
IV
Aortic arch (from left side)
Right subclavian artery (proximal portion) (from right side)
VI
Pulmonary arteries (from proximal portions of right and left side)
Ductus arteriosis (from distal portion of left side)
III
Internal carotid artery (proximal portion)
Common carotid arteries
Dorsal aorta
Ventral aorta
Heart input
Umbilical veins (L and R)
Vitelline veins (L and R)
Common cardinal veins (L and R)
Anterior cardinal vein
Posterior cardinal vein
Process
Cardiogenic plate: Angiogenic cell clusters form endocardial tubes
Endocardial tubes move laterally to form primitive heart tube
Layer Organization
Myocardium
Cardiac jelly
Epicardium
Endocardium
From Primitive Heart to Heart
Chamber formation
Atria formation
Ventricle formation
Septation
Folding
Ventricles grow caudally, atria grow cephalically
S shaped
Regulate circulation
Birth defects
Aortic coarctation
Due to malformation in IV or VI aortic arch
