Truncus arteriousus gives rise to:
|
ascending aorta
pulmonary trunk |
|
|
bulbus cordis
|
smooth parts - outflow tract of left and right ventricles
|
|
|
primitive ventricle
|
trabeculated left and right ventricles
|
|
|
primitive atria
|
traveculated left and right atria
|
|
|
left horn of sinus venosus
|
coronary sinus
|
|
|
right horn of SV
|
smooth part of right atruium
|
|
|
right common cardinal vein and right anterior cardinal vein
|
SVC
|
|
|
Truncus arteriosus development
|
neural crest migration: truncal and bulbar ridges spiral and fuse --> aorticopulmonary septum
- transposition of great vessels - failure of spiral - tetralogy - skeqed AP septum - persistent TA - partial AP septum development |
|
|
Interventricular septum development
|
1. muscular ventricular septum forms
2. AP septum rotates and fuses w/ muscular ventricular septum to form membranous inter- ventricular septum, closing interventricular foramen 3. Endocardial cushions separates atria from ventricles |
|
|
Aortic Arches 1 - 6
|
1. part of maxillary a.
2. stapedial a. and Hyoid a. 3. common carotid, proximal part of internal carotid 4. left - arch of adult aorta; rt - proximal part of rt. subclavian a. 5. nothing 6. proximal part of pulm arteries, ductus arteriousis |
|
|
Interatrial septum development
|
1. foramen 1* narrows, septum 1* grows toward endocardial cushions
2. perforations in septum 1* form foramen 2* (foramen 1* disappears) 3. foramen 2* maintains R-L shunt as septum2* grows 4. septum 2* contains a permanent opening - foramen ovale 5. foramen 2* enlarges and upper part of septum 1* degenerates 6. remaining septum 1* forms valve of foramen ovale 7. septum 2* and septum 1* fuse to form the atrial septum 8. foramen ovale usually closes after birth |

keep close: Indomethacin |
|
|
umbilical vein
|
ligamentum teres hepatis
contained in falciform ligament |
|
|
umbilical arteries
|
medial umbilical ligament
|
|
|
ductus arteriosus
|
ligamentum arteriosum
|
|
|
ductus venosus
|
ligamentum venosum
|
|
|
foramen ovale
|
fossa ovalis
|
|
|
allntois
|
- urachus median umbilical ligament
- urachus is part of allontoic duct bw the bladder and the umbilicus - urachal cyst or sinus is a remnant |
|
|
notochord
|
nucleus pulposus of intervertebral disc
|
