levels of the inferior vena cava

Answer 22

the level of L5 – runs on right side of vertebral column – is partially embedded in the liver before
passing through the caval opening of the diaphragm at T8, and entering the right atrium

Question 23

Tributaries of the inferior vena cava

Answer 23

Renal veins (at the level of L1, drain the
kidney) and the gonadal veins (ovarian/testicular) (at level of L2)

Question 24

what is weird about eh left renal vein?

Answer 24

Note the left renal vein often
receives the left gonadal vein in contrast with the right side where the gonadal and other veins
drain directly into the IVC

Question 25

what do the hepatic veins drain from and where does this blood go to

Answer 25

(drain blood from the liver into the inferior vena cava)

Question 26

why is The hepatic portal vein not a real vein

Answer 26

n as it conducts blood to the capillary bed in the liver and not directly to the heart)

Question 27

what do the hepatic portal veins drain from and where does this blood go to

Answer 27

(drains blood from the gastrointestinal tract and spleen to liver

Question 28

Tributaries of the hepatic portal veins

Answer 28

include the splenic vein, superior and inferior mesenteric veins,
gastric veins and cystic veins

Question 29

where does the superior vena cava drain blood from

Answer 29

drains blood from the head, neck and upper limbs

Question 30

how is the superior vena cava formed

Answer 30

formed by the

union of the brachiocephalic veins.

Question 31

what joins the superior vena cava join before it gets to the right atrium

Answer 31

The azygos vein joins it just before it enters the right atrium

Question 32

where does the the azygos vein drain from

Answer 32

(drains blood from the posterior intercostal space, the posterior abdominal
wall, pericardium, diaphragm, bronchi and oesophagus in conjunction with the superior
hemiazygos

Question 33

useful landmarks for the identification of the femral artery

Answer 33

anterior superior iliac spine, pubic tubercle and pubic symphysis

Question 34

The internal iliac artery

supplies

Answer 34

the pelvic organs and gluteal region (buttock)

Question 35

external iliac mainly supplies

Answer 35

the lower limb

Question 36

what is the femoral triangle?

Answer 36

a triangular depression at the

front of the thigh made up of the femoral artery and femoral vein

Question 37

what is the popliteal fossa

Answer 37

(a diamond shaped

depression behind the knee)

Question 38

what do we find in the middle of the popliteal fossa

Answer 38

the popliteal artery and popliteal vein

Question 39

where is the posterior tibial artery

Answer 39

behind the medial malleolus

Question 40

where is the dorsalis pedis artery,

Answer 40

running distally on the dorsum of the foot between the tendon of
extensor hallucis longus and the medial tendon of extensor digitorum longus

Question 41

landmarks of the radial artery

Answer 41

tendon of flexor carpi radialis

Question 42

where is radial artery relative to the tendon of flexor carpi radialis

Answer 42

lateral

Question 43

The junction between the internal jugular and subclavian veins to form

Answer 43

the

brachiocephalic vein

Question 46

where does the superficial temporal artery criss the zygomatic arch

Answer 46

anterior to the ear

Question 47

Where is the cephalic vein

Answer 47

arising from the lateral (thumb side) of the dorsal venous network on the
dorsum (back) of the hand, and running superiorly towards the lateral side of the cubital fossa

Question 48

Where is the basillic vein

Answer 48

arising from the medial (little finger side) of the same network and running
superiorly towards the medial side of the cubital fossa

Question 49

greater (long) saphenous vein

Answer 49

as it arises from the medial marginal vein (from the most
medial aspect of the dorsal venous network of the foot) and passing anterior to the medial
malleolus as it runs superiorly on the medial aspect of the leg

Question 50

lesser (short) saphenous vein

Answer 50

as it arises from the lateral marginal vein (from the most
lateral aspect of the dorsal venous network of the foot), and passing posterior and inferior to the
lateral malleolus as it runs superiorly on the posterior aspect of the leg

Question 51

how to find upper limb veins

Answer 51

 Apply a tourniquet to the middle of one arm (at least 4 finger breadths above the cubital fossa -
the depression anterior to the elbow)
 Ask the subject to make a tight fist (using the arm with a tourniquet) then release it, and keep
doing this until the cubital and antecubital (forearm) veins are clearly visible.

Question 52

how to find lower limb veins

Answer 52

Apply a tourniquet to the middle of the calf and keep the lower limb on the floor, looking for
the superficial veins on the leg, ankle and foot to become clearly visible.
