Q

pelvis, abdominal wall, and lower limbs

21
Q

What are the branches of the common iliac artery?

A 
internal iliac (hypogastric)
external iliac
22
Q

Where does the external iliac artery travel along?

A

the medial portion of the psoas major muscle

23
Q

what does the CIA become after the inguinal ligament?

A

CFA

24
Q

What does the CFA divide into?

A

SFA and DFA

25
Q

How does the SFA run?

A

runs the length of the thigh, passing through an ipeing in the tendon of the adductor hiatus (AKA adductor canal or Hunters canal) enters the pop fossa behind the knee

26
Q

Describe the DFA AKA profunda artery

A

a large branch, arises about 5 cm from the inguinal ligament on the lateral side
can act as a collateral

27
Q

When does the Pop Artery start?

A

at adductor hiatus: termination of the SFA and beginning of the pop

28
Q

What does pop art give off to?

A

gives off number of genicular branches to supply muscles, knee joint and skin

29
Q

What does the pop art divide into?

A

at interval between tibia and fibula, ATA and PTA

30
Q

What is the first branch of the pop a?

A

ATA

31
Q

What does the ATA become?

A

DPA and is directed across dorsum of the foot towards base of the great toe

32
Q

What is a major branch of the DPA?

A

deep plantar artery

33
Q

How is the complete plantar arch formed?

A

the unification of the lateral plantar artery with the deep plantar artery

34
Q

Where is the PTAs?

A

extends obliquely down posterior/ medial side of the leg

35
Q

What is the tibioperoneal trunk?

A

short segment between the ATA branch and branches of the PTA and peroneal arteries

36
Q

What are the major branches of the PTA?

A

lateral and medial plantar arteries, branching below the medial malleolus to supply sole of the foot

37
Q

Where does the peroneal arteries travel?

A

passes toward the fibula, traveling down the medial side of that bone to supply structures of the lateral side of the leg/foot

38
Q

what arteries distribute blood to the toes digits?

A

the plantar and dorsal metatarsals

39
Q

What do arteries transport?

A

gases, nutrients, and other essential substances to capillaries.

40
Q

Do arteries increase or decrease in size as they travel distally?

A

decrease

41
Q

arterioles are considered what?

A

resistance vessels, assist with regulating blood flow through contraction and relaxation

42
Q

What do capillaries transport?

A

nutrients and waste products are exchanged between tissue and blood

43
Q

what are the vessels of microcirculation?

A

capillaries and arterioles

44
Q

what is tunica intima/ inner layer consist of?

A

a thin surface layer of smooth endothelium, base membrane, and connective tissue

45
Q

what is tunica media/ intermediate layer consist of?

A

thicker, smooth muscle and connective tissue; largely of the elastic type

46
Q

what is tunica externa/ outer layer (adventitia) consists of?

A

thinner than media, contains fibrous connective tissue; some muscle fibers

47
Q

which layer contains the vasa vasorum?

A

adventitia

48
Q

What is the vasa vasorum?

A

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