  1. What structure becomes the portal vein?
    right vitelline vein
  2. Main venous drainage of the embryo
    cardinal veins
  3. Anterior and posterior cardinal drainage
    • ant is the head
    • pos is the body
    • the common cardinal enters into the sinus venosus
  4. What structure becomes the left brachiocephalic vein
    • the shunt that develops between the right and left anterior cardinal veins
    • the anterior cardinal develop into the right and left jugular veins and the SVC
  5. Only adult derivative of the posterior cardinal veins
    root of the azogus and the common iliac
  6. gonadal veins are from
  7. coronary sinus develops from
    left horn of sinus vinosous
  8. left common cardinal becomes
    oblique vien of left atrium
  9. azogus and hem azogus are from
  10. adrenal veins are from
  11. double SVC is from
    persistent left anterior vittaline vein
  12. abdominal aorta is formed from
    fusion of the dorsal aortas
  13. common iliac arteries are form
    5th pair of lumbar arteries
  14. three remnants of the posterior vitelline arteries
    celic trunk, superior and inferior mesentaric
  15. median umbilical ligaments
    distal umbilical arteries
  16. proximal umbilical arteries become
    internal iliacs and superior vesical arteries
  17. epicardial cells are derived from
    sinos venosous
  18. smooth part of right atrium
    sinus veneroum
  19. visual markers of meeting of primordial atrium and sinus venosoum
    crista terminals and the sulcus terminals
  20. three structures that meet to form the IV membranous septum
    left and right bulbar ridges and the endocardial cushion
  21. ventricular outflow
    • right is the conus arterioles
    • left is the aortic vestibule
  22. What TGF factor is involved in looping of the heart
  23. situs inversus
    transposition of the abdominal viscera
  24. Ectopia aordis
    • abnormal location of the heart
    • can be on the outside of sternum
  25. What two cardiac anomalies are usually seen together with incomplete absorption of the sinus venosoum
    • sinus venomous (high) ASD
    • partial anomalous venous return
  26. What other cardiac defect is usually seen with cor trilocular biatrium
    transposition of the great vessels
  27. What is always present with truncus arterioles
  28. What distinguishes aortopulmonary window from PTA
    presence of semilunal valves with window
  29. Two types of pulmonary stenosis
    • infundibular stenosis
    • pulmonary valve
  30. 1st pharingeal arch
    • maxillary arteries
    • some of external carotid
  31. 2nd pharyngeal arches
    stapedial arteries to middle ear
  32. 3rd pharyngeal arches
    • common carotids - proximal parts
    • internal carotids- distal parts
  33. 4th pair pf pharyngeal arches
    • left becomes arch of aorta
    • right is proximal subclavien artery
  34. 5th pharyngeal arches
  35. 6th pharyngeal arches
    • left is the left pulmonary artery and the ductus arterioles
    • right right pumonaly artery
    • the recurrent laryngeal nerves supply this set of arches, the right detail arch degenerates and explains why the right recurrent laryngeal nerve is located higher, it ascends up. The left is hooked around the ductus arterosus
  36. Coarctation is associated with
    turners syndrom
  37. three main views on how coarctation occurs
    • some muscle from the DA incorporates into the wall and constricts after birth
    • just small
  38. vascular ring of aorta around the trachea
    abnormality of the 4th paryngeal arch
  39. function of DV sphincter
    contracts to shunt blood to the hepatic sinusoids to protect overload of the heart
  40. inferior border of the septum secundum
    crista dividens
  41. What is released by the lungs and activated by oxygen to constrict the DA
  42. left umbilical vein becomes?
    round ligament of the live (ligamentum teres)
  43. most common abnormality with maternal rubella infection
