1
arteries, veins, and lymphatic channels form from what embryonic layer
mesoderm
2
what forms first extraembryonic vessels or embryonic vessels ?
extraembryonic
3
when do the pharyngeal arches form ?
4th and 5th weeks of development
4
the first arch gives rise to
maxillary artery
5
the second arch gives rise to
hyoid and stapedial arteries
6
the third arch persists and gives rise to
common carotid and internal carotid arteries
7
the fourth arch gives rise to
the right 4th arch persists as the right subclaviian artery
the left 4th arch persists as a segment of the aortic between the origin of the left common carotid and left subclavian
8
the right 6th arch gives rise to
right pulmonary artery
9
the left 6th arch gives rise to the
left pulmonary artery and ductus arteriousus
10
what is the carotid duct
connects the 3rd and 4th arches
11
what nerves supplies the 6th arch
recurrent laryngeal nerve
12
general function of the vitelline arteries
arise from the abdominal aorta and supply derivatives of the yolk sac
13
the thoracic vitelline arteries supply what
esophagus
14
the celiac artery supplies
foregut
15
superior mesenteric arteri supplies
midgut
16
inferior mesenteric artery supplies the
hindgut
17
the umbillical arteries are first paired branches of the dorsal aorta that supply what?
allatois
18
umbilical arteries in adulthood are what
medial umbillical ligaments
19
dysphagia lusoria
abnormal origin of the subclavian artery
20
Anomalies associated with development of the arterial system /
patent ductus arteriousus
coarctation of the aorta
dysphagia lusoria
double aortic arch
21
What are the three system of veins that can be observed during the 5th week of development ?
vitelline, umbilical and cardinal
22
Function of the vitelline veins
carry blood from yolk sac to sinus venosus
23
function of the umbilical veins
carry oxygenated blood from the placenta to the embryo
24
Function of the cardinal veins
drain blood from the rest of the embryo and deliver it to the Right side of the heart
25
Veins derived from the vitelline veins
small region of IVC
portal vein
hepatic vein
ductus venosus
superior mesenteric
inferior mesenteric
splenic
26
distal portion of the left umbilical veins carries blood
from the placenta towards the liver
27
what is the communication between the left umbilical and the right vitelline called
ductus venosus
28
function of the ductus venosus
bypasses the sinusoids of the liver so that blood reaching the liver has the highest oxygenated and nutritional content bypassing the capillary beds this blood reaches the heart and brain and not the liver
29
after birth the left umbilical vein becomes
liigamentum teres hepatis
