Development of Arch arteries Flashcards
Cranial most part of Truncus arteriosus forms
Aortic sac
Aortic sac formed by
Cranial most part of Truncus arteriosus
What happens to 1st and 2nd arch arteries
Disappears
Arch of aorta is derived from
Left horn of Truncus arteriosus + Left 4th arch of aorta + Left dorsal aorta - caudal part.
Right dorsal aorta caudal part -
Disappears
Double aortic arch - Pathogenesis
Persistence of Right dorsal aorta - caudal part
Persistence of Right dorsal aorta - caudal part causes
Double aortic arch
Left brachiocephalic trunk derived from
Right horn of aortic sac
Common carotid artery derived from
Proximal part 3rd arch artery
Proximal part 3rd arch artery gives rise to
Common carotid artery
Carotid bud is on which arch artery
3rd arch Artery
3rd Arch Artery is gives rise to
Carotid bud
Internal Carotid Artery is derived from
Distal 3rd arch Artery + Cranial part of dorsal aorta.
Distal 3rd arch Artery + Cranial part of dorsal aorta gives rise to
Internal Carotid Artery
Right subclavian Artery is derived from
Right 4th arch Artery + 7th intersegmental Artery + dorsal aorta cranial to intersegmental artery.
Left subclavian Artery is derived from
Left 7th intersegmental artery
4th arch Artery on left side forms
Arch of Aorta
4th arch artery on right side forms
Right subclavian Artery
Abnormal Right subclavian Artery - pathogenesis
Disappearance of Right 4th arch Artery and Right dorsal aorta cranial to 7th intersegmental artery.
Persistence of 7th intersegmental artery + Right dorsal aorta caudal to 7th ISA
Lusoria artery is
Abnormal Right subclavian Artery
Pulmonary artery is derived from
Proximal part of 6th arch artery
Left distal arch artery -
disappears
Right distal arch artery -
forms ductus arteriosus.
Ductus arteriosus -
connects Pulmonary artery to Arch of Aorta
Ductus arteriosus closes at
Birth.
PDA is ____ HD
Acyanotic Heart Disease
Cyanotic Heart Disease are
TOF, TGA.
