Q

What are the differences with between the arteries and veins?

A
  1. Tunica media: the arteries are thicker and holds shape of vessel while the vein has a thinner tunica which allows for compressibility
  2. Valves: The arteries have none and flow controlled by systole and muscle contractions. Meanwhile, the veins have valves and a one at flow towards hearts, and are located in the upper and lower extremities
  3. Veins are deep and superficial

What is the subclavian vein?

A
  1. Travel posterior and superior to clavicle
  2. Continues horizontal towards heart
26
Q

Where are the right and left Brachiocephalic veins formed?

A

Formed by the junction of the subclavian veins and jugular veins

27
Q

What forms the superior vena cava? And where does it drain into?

A

Right and left Brachiocephalic veins do, and they drain into right atrium

28
Q

What are three superficial veins?

  1. Cephalic veins
  2. Basilic vein
  3. Median cubits vein
29
Q

What does the cephalic vein do?

  2. Ascends along lateral arm
  3. drains directly into axillary vein
30
Q

What is the basilic vein?

A
  1. Starts at medial aspect of hand
  2. Ascends along posterior medial aspect of arm
  3. Located medial to brachial veins
  4. Joins brachial vein to form axillary vein
31
Q

What are the arteries of lower extremities?

A
  1. Aorta
  2. Common iliac arteries
  3. Internal iliac arteries
  4. External iliac arteries
32
Q

What is the Aorta?

A

Bifurcates at the L4 into right and left Common iliac arteries

33
Q

What are the common iliac arteries?

A
  1. Travel Inferiorly and slightly laterally in pelvis
  2. Arteries pass laterally and anterior to CI veins
  3. Divides into internal and external IA
34
Q

What is the internal iliac arteries?

A
  1. Descends posterior and medial into pelvis
  2. Supplies the pelvic viscera and muscles
35
Q

What are the external iliac arteries?

A

Travel laterally towards leg

36
Q

What is the common femoral artery?

A

External iliac becomes the CFA at the inguinal ligament

37
Q

What is the superficial and deep femoral arteries?

A

The CFA bifurcates to become the superficial femoral artery (Femoral artery) and the deep femoral artery (profunda artery)

38
Q

What is the popliteal artery?

A

1.The Superior femoral artery travels down the thigh and passes through the adductor canal to become the popliteal artery.
2. Posterior to knee
3. Popliteal artery anterior to popliteal vein

39
Q

What is the anterior tibial artery?

A
  1. Branches off the popliteal artery
  2. Travels along anterior part of lower leg
  3. Becomes dorsalis pedis arteries in foot
40
Q

What is the tibioperoneal trunk arteries

A

Branches into the posterior Tibial artery (posterior and medial) and the peraneal artery (posterior and lateral)

45
Q

What are the anterior tibial veins?

A

  2. Unite to form anterior tibia trunk which drains into the popliteal vein
46
Q

What is the posterior tibial veins?

A
  1. Ascend along posterior and medial aspect of lower leg
  2. Drain into tibioperoneal trunk
47
Q

What are the perineal veins?

Q

What is the popliteal vein?

A
  1. Union of anterior tibial trunk and the tibioperoneal trunk
  2. Posterior aspect of knee
  3. Vein is posterior to artery **
  4. Becomes superficial fearless vein superior to knee and adductor
49
Q

What is the superficial femoral vein?

A

The Popliteal vein becomes the SFV superior to the knee AKA femoral vein

50
Q

What is the Common femoral vein?

A

The SFV (FV) joins the DFV (profunda) at the inguina ligament to become the CFV

51
Q

What is the external iliac vein?

A
  1. As it enters the pelvis, the CFV becomes the External iliac veins
  2. Superior and medial course
  3. Joints internal iliac vein to form CIV
52
Q

What is the common iliac vein?

A
  1. Forms at the level of SI joint
  2. The CIV unites at L5 to form the IVC
  3. CI veins are posterior to arteries
