Q

6th arch artery is also known as ___

A

pulmonary arch arteries

29
Q

If 7th intersegmental artery is not an arch artery, why is it grouped with them?

A

it also drains into the dorsal aorta

30
Q

Where is the 7th intersegmental artery located

A

lower – closer to where the dorsal aorta come together in the thoracic cavity

31
Q

Which side of the dorsal aorta is mostly maintained?

A

left side is maintained - runs entire length of embryo

(think: left side dorsal aorta becomes descending thoracic aorta…. right side becomes PART of right subclavian artery, so mostly goes away)

32
Q

The path for R/L recurrent laryngeal nerve is different because of asymetrical development of what?

A

6th arch arteries and the recurrent laryngeal nerves

33
Q

Originally, the laryngeal nerve arises below the ___

what is it’s relationship to this?

A

6th aortic arch

crosses under this to innervate the intrinsict mm of larynx

34
Q

During development, the larynx is translocated in which direction relative to what?

A

caudal relative to arch arteries

35
Q

Left recurrent laryngeal nerve is caught under ____

which remains looped under the future ___

A

caught under 6th arch

remains looped under the future LIGAMENTAL ARTERIOSUM

36
Q

Right recurrent laryngeal nerve is caught under ___

Why?

A

under 4th arch artery = right subclavian artery

because distal part of 6th arch artery disappears

37
Q

Vitteline arteries fuse to form arteries in the ____

A

dorsal emsentery of the gut

38
Q

Vitteline arteries will develop into ___

A

celiac artery

superior mesenteric artery

39
Q

Umbilical artery is initially a paired branch off of dorsal aorta on the ___ side

A

ventral

40
Q

The original connection bw umbilical artery and dorsal aorta develops into ___

A

inferior mesenteric artery

41
Q

During week __ a secondary connection bw umbilical artery and dorsal aorta is formed

A

4

42
Q

The secondary connection (week 4) between umbilical artery and dorsal aorta becomes ____

A

common iliac artery

43
Q

After birth, does the umbilical artery persist?

A

yes
inferior mesenteric artery, common iliac artery
&
proximal portion = internai iliac and superior vesical artery
distal portion = medial umbilical ligaments

44
Q

Intersegmental arteries become ___

A

intercostal artery

lumbar artery

45
Q

Coronary arteries are derived from ___

A

epicardium

46
Q

The connection between coronary arteries and the aorta is formed by an ingrowth of ___

A

arterial endothelial cells

47
Q

The venous system is developed from __ to __

A

fetal period to neonate period

48
Q

Embryonic venous system is 3 paired veins. What are they?

A

viteline veins
umbilical veins
cardinal veins

49
Q

oxygenated or deoxygenated:
vitelline veins __
umbilical veins __
cardinal veins __

A 
vitelline = deoxygenated
umbilical = oxygenated
cardinal = deoxygenated
50
Q

Vitelline veins drain ____

A

gi tract and gut derivatives

51
Q

Vitelline veins drain into the __

A

sinus venosus

52
Q

Umbilical veins carry blood from ___ to the ___

A

placenta to the embryo

to the sinus venosus

53
Q

Is the umbilical vein functional in adults?

A

no

54
Q

Are vitelline veins functional in adults?

A

yes

drain gi tract and gut derivatives

55
Q

Cardinal veins drain blood from ___

A

all of head, neck, body wall

56
Q

What combines to create the common cardinal vein?

A

anterior cardinal vein + posterior cardinal vein

57
Q

There are __ primary lymph sacs

A

6

58
Q

What are the 6 primary lymphatic sacs?

A

2 jugular sacs
2 iliac sacs
1 retroperitoneal sacs
1 cisterna chyli

59
Q

Where are the 2 bilateral jugular lymph sacs located?

A

at the junction of the subclavian vein and the anterior cardinal vein (will become internal jugular vein)

this is near the venous angle

60
Q

Where are the 2 bilateral iliac sacs located?

A

at the junction of the iliac veins and posterior cardinal veins

at the most caudal end of the embryo

61
Q

Where is the 1 retroperitoneal sac found?

A

in front of the inferior vena cava

in the root of the mesentery on the posterior abdominal wall

62
Q

Where is the 1 cisterna chyli lymph sac found?

A

dorsal to the retroperitoneal lymph sac

63
Q

Initially, are all of the primary lymphatic sacs connected?

A

no

they are all initially separated

64
Q

The right and left THORACIC DUCTS initially connect the ___ with the ___

A

jugular sacs (2) with the (1) citerna chyli

65
Q

____ ultimately connect all of the primary lymphatic sacs

A

lymphatic vessels

66
Q

lymphatic vessels ultimately connect all of the primary lymph vessels to the ____

A

venous angles (on either side)

67
Q

The aortic arch is formed from which pharyngeal arches?

A

LEFT pharyngeal arch 4

and LEFT aortic sac

68
Q

The LEFT subclavian artery is formed from which pharyngeal arch arteries?

A

LEFT 7th intersegmental artery

69
Q

A

RIGHT 4th arch
RIGHT 7th arch
RIGHT dorsal aorta
