Flashcards in Chapter 1: Arterial Gross Anatomy Deck (56):
1

First branch of ascending aorta are the

coronoary arteries

2

the coronary arteries arise

proximal to arch

3

branches of aortic arch

innominate/brachiocephalic
lt cca
lt subclavian artery

4

innominate/brachiocephalic trunk divides into

rt cca
rt subclavian artery

5

subclavian artery runs

laterally to outer border of 1st rib, becomes axillary artery

6

branches of subclavian artery

vertebral
thyrocerical
costocervical

7

brachial artery

branches into radial and ulnar arteries at antecubital region / elbow

8

radial artery travels

down lateral forearm into hand

9

radial artery branches to form:

superficial palmar (volar arch)

10

the radial artery terminates

in deep palmar arch by joining a branch of the ulnar artery

11

the ulnar artery travels

down medial side of forearm into hand

12

the ulnar artery branches to form

deep palmar (volar) arch

13

the ulnar artery terminates

in superficial palmar arch

14

main source of blood flow to the hand is from the

ulnar artery

15

superficial palmar (volar) arch includes

distal portion of the ulnar artery
branch of radial artery

16

the deep palmar arch includes

deep palmar branch of ulnar artery
distal portion of radial artery

17

abominal aorta branches

celiac
SMA
renal arteries
IMA
bifurcation

18

Celiac Artery supplies

stomach, liver, pancreas, duodenum, spleen

19

the celiac artery branches into

l. gastric
common hepatic
splenic

20

the superior mesenteric artery supplies

small intestine
cecum
parts of colon

21

the SMA is located

1cm distal to celiac artery (can have a common trunk with celiac)

22

Renal arteries supply blood to

kidneys
adrenals
ureters

23

landmark for locating the left renal artery in trv

lt renal vein crosses aorta anteriorly, lt renal artery is just posterior to this

24

the common iliac arteries carry blood to

pelvis and lower limbs

25

the common iliac arteries divide into

internal and external iliacs

26

internal iliac artery is also known as

hypogastric artery

27

external iliac artery travels

medial to psoas major and passes underneath inguinal ligament

28

external iliac artery becomes

common femoral artery

29

the common femoral artery divides into

superficial femoral
deep femoral or profunda arteries

30

the superfical femoral arteries run

lengh of thigh, passing through adductor hiatus (adductor canal, Hunter's canal)
enters pop fossa behind knee

31

Deep Femoral (profund femoris) artery is

a large branch
arises 5cm distal to inguinal ligament on lateral side
can act as a collateral connection

32

Adductor hiatus is the

termination point of the SFA and beginning of pop artery

33

the popliteal artery supply blood to

muscles
knee joint
skin

34

the popliteal artery divides into

anterior and posterior tibial arteries between tib/fib

35

Anterior tibial artery

first branch off pop artery

36

the anterior tibial artery becomes

dorsalis pedis artery (DPA)
directed across dorsum of foot towards base of great toe

37

Major branch of the dorsalis pedis artery is the

deep plantar artery

38

the deep plantar artery unites with

lateral plantar artery to complete plantar arch

39

the posterior tibial artery extends

obliquely down posterior/medial side of leg

40

major branches of the posterior tibial arterys are the

lateral and medial plantar arteries

41

lateral and medial plantar arteries branches

below medial malleolus to supply sole of foot

42

the peroneal artery travels

medial side of fibula

43

the peroneal artery supplies

lateral side of leg and foot

44

what arteries supply blood to toes

plantar and doral metatarsals

45

the plantar arch consists of

deep plantar artery (branch of DPA) and lateral plantar artery (branch of PTA)

46

arteries transport

gasses
nutrients
essential substances to capillars

47

arteries ____ in size from aorta to arterioles

decrease

48

arterioles are considered

resistance vessels

49

arterioles assist with

regulating blood flow through contraction and relaxation

50

capillaries are the site of

exchange between tissue and blood, exchange nutrients and waste

51

Layers of arterial wall

tunica intima
tunica media
tunica externa (adventicia)

52

tunica intima

inner layer
thin
smooth endothelium, base memebrane, connective tissue

53

tunica media

middle layer
smooth muscle, connective tissue of elastic type

54

tunica exerna/tunica adventitia

thinner than media
fibrous conntective tissue
some mucle fibers

55

the advential layer contains

vaso vasorum

56

vaso vasorum are

tiny vessels that carry blood to the walls of the larger arteries
