Desesso Cardio Embryology Flashcards
Where will you see mixed blood with an Interventricular Septal defect causing Persistent Truncus Arteriosus?
Both the carotid and pulmonary branches, because the lung bypass is still open and the ventricles are mixed.
Notable use of Intussusception in Cardo development?
Pulmonary veins fusing the Left Atrium to umbrella open
Arch 6; R/L
R: Pulmonary Artery
L: Pulmonary Artery AND Ductus arteriosus
“Six fix breath”
In cardio embryology, Canon wnts tell the cells to:
Stay/ stasis
Dorsal Aorta; R/L
R: Int. Carotid, (Disappears with neck growth), Central Right subclavian, (Dissappears)
L: Internal Carotid (disappears), Descending Aorta
Arch 4; R/L
R: Proximal Right Subclavian Artery
L: Arch of the Aorta (Medial portion)
In cardio embryology, Non-canon Wnts tell the cells to:
Divide
Four components of Tetraology of Fallot
- Pulmonary Stenosis
- R. Ventricular hypertrophy
- Membranous Intervent. Septal Defect
- Overriding Aorta
(poor blood flow in aorta)
Ventral Aorta; R/L
R: Ext. Carotid, Common Carotid, Brachiocephalic Artery
L: Ext. Carotid, Common Carotid, Ascending Aorta
Arch 2; R/L
R: Hyoid artery, Stapedial artery (disappears)
L: Hyoid artery, Stapedial artery (disappears)
“Getting high at staples”
Arch 3; R/L, Proximal and Distal for each
R: Proximal arch makes Common Carotid, Disal Arch makes Internal Carotid
L: “”” Same
“Then neck is near and far”
The _____ Valves form from erosion, exposing the Chordae Tendinaea above the papillary muscles.
Atrioventricular (Tri and Bi-cuspid)
Relative anatomical position of the Ventricles
Inferior and Anterior
“Try hards”
Three Cyanotic congential heart defects
- Tetralogy
- Transposition of great arteris
- Atrioventricular Septal defect
Relative anatomical position of the Atria
Superior and Posterior
“Cheat Seats”
In cardio embryology, the _____ interacts with the Cardiac Mesoderm using FGF8 and a Retinoic acid gradient to organize the cardiogenic plate.
Anterior Visceral Endoderm (AVE)
Arch 1; R/L
R: Maxillary Artery
L: Maxillary Artery
“The Maxiumum is #1”
