embryology Flashcards
the 1 and 2nd aortic arches form the
maxillary arteries
the 3rd aortic arch forms the
common carotid
the left side of the fourth aortic arch forms the
arch of aorta
the right side of the fourth aortic arch forms the
right subclavian artery
the 6th left aortic arch forms the
left pulmonary artery and the ductus arteriosus
the 6th right aortic arch forms the
right pulmonary artery
great artery anomalies examples
aberrant subclavian artery
double aortic arch
patent ductus arteriosus
coarctation of the aorta
the artery of the foregut forms
the celiac artery
the vitelline artery of the midgut forms the
superior mesenteric artery
the inferior mesenteric artery is formed by
the artery of the hindgut
the proximal portions of the umbilical arteries form
internal iliac and superior vesical branches
the distal portion of the umbilical arteries form the
obliterate and form the medial umbilical ligaments
vitelline veins carry blood from
from the yolk sac to the sinus venosus
vitelline veins form
portal vein
hepatocardiac portion of the inferior vena cava
liver sinusoids
superior mesenteric vein
the right umbilical vein forms
degenerates completely
left umbilical vein forms
obliterates and forms the ligamentum teres of the liver
the ductus venosus forms
obliterates and forms the ligamentum venosum
the cardinal veins forms
vena caval system
venous system abnormalities
double IVC
absence of IVC
left SVC
double SVC
what are the 4 primary lymphatic sacs
internal jugular
retroperitoneal lymph sac
cisterna chyli
iliac lymph
the route of fetal circulation
aorta carrying deoxygenated blood descending aorta abdominal aorta common iliac artery umbilical artery placenta oxygenated blood along the umbilical veins
the four major stages in heart development are
bilateral heat primordia primitive heart tube heart looping atrial and ventricular septation outflow tract septation
pericardium is derived from
the intra embryonic coelom
the sections of the primitive heart tube are
truncus arteriosus bulbus cordis ventricle atrium sinus venosus
abnormal cardiac looping is called
dextrocardia
name of the two septum and foramina
septum primum and foramen primum
septum secundum and foramen secundum
the oval foramen perforates the
septum secundum
failure to from the oval fossa from the fusing of the septum primum with the septum secundum is called
atrial septal defect.
what are the four types of ASD?
foramen secundum defect
endocardial cushion defect with foramen primum defect
sinus venosus defect
common atrium
the most common type of ventricular septal defect is
membranous
the aortic sac forms
aortic arches
the bulbis cordis forms
right ventricle
parts of the outflow tracts
primitive ventricle forms
left ventricle
primitive atrium forms
parts of right and left atria
sinus venosus forms
superior vena cava right atrium
transposition of great vessels are caused by
failure of the aorticopulmonary septum to take a spiral course
the defective migration of neural crest
tetralogy of fallot is made up of 4 cardiac defects
pulmonary stenosis
ventricular septal defect
dextroposition of aorta
right ventricular hypertrophy
vasculogenesis refers to
formation of NEW vessels
angiogenesis refers to
growth of existing vessels
