Common Hepatic, Splenic, Lt Gastric artery are branches arising from what
Abdominal artery? * Correct Answer: Celiac Trunk* (1st major branch of Abd
AO, divides into Common Hepatic, Splenic, Lt Gastric arteries)*

Most common anatomic variant of the Renal arteries: Correct Answer: Multiple
Renal artery* (commonly originate from Abd Ao or Common Iliac arteries, esp w/
ectopic, horseshoes kidneys)

Tiny IntraRenals branches that arise at the Rt angles from the Interlobar arteries
and course above the Renal pyramids are the: Correct Answer: Arcuate arteries*
(main renal divides at the Hilum into Segmental renal arteries w/in Renal Cortex,
Arcuate give rise to the radially orientated Interlobular artery)

At the Inguinal ligament*, the External Iliac artery becomes what peripheral
artery? Correct Answer: Common Femoral Artery*

Dorsalis Pedis* is a continuation of which of the following arteries? Correct
Answer: Anterior Tibial Artery*

Small intestine, right colon, transverse colon are supplied by: Correct Answer:
Superior Mesentric Artery* (2nd major artery of Abd Ao, arises below origin of
Celiac Trunk)*

The largest branch of the Celiac Trunk* is the: Correct Answer: Splenic artery*

,Hypogastric artery* is another name for the: Correct Answer: Internal Iliac artery*

Which of the following vessels courses along the medial aspect of the Psoas
Muscle*? Correct Answer: External Iliac Artery*

1st branch of the External Carotid Artery* is usually the: Correct Answer:
Superior Thyroid Artery*

Vertebral Artery enters the Transverse Foramina of the Cervical spine at what
level? Correct Answer: C6*

Name the Vessels of the Circle of Willis* Correct Answer: a) Middle Cerebral
Artery
b) Anterior Communicating
c) Anterior Cerebral
d) Internal Carotid
e) Posterior Communicating
f) Posterior Cerebral
g) Basilar
h) Vertebral

3 major branches of the Ophthmalmic artery* are: Correct Answer: Frontal
Supraorbital
Nasal

Basilar artery* divides into which artery? Correct Answer: Posterior Cerebral
Arteries

ECA provides an anastomotic link* to the ICA through the Orbit via which of the
following vessels? Correct Answer: Superior Temporal Artery*
(ECA can supply ICA thru periorbital circulation.
- Ophthalmic artery have anatosmotic links w/ ECA branches, these connections
can provide blood flow to the intracranial circulation in cases of ICA occlusion via
retrograde flow thru the Ophthmalic.
- Surpraorbital and frontal connect ECA thru Superficial temporal.
- Nasal becomes angular artery as it descends along lateral border of the nose and
connects the ECA via facial artery)

,All of the following arise from the Intracranial ICA EXCEPT: Correct Answer:
Ascending Pharyngeal
- MCA
- ACA
- PCoA

Opthmalmic Artery is a branch of the: Correct Answer: Internal Carotid artery
(ICA)*

In the case of the ICA occlusion, all of the following are potential collateral
pathways to perfuse the Ipsilateral Cerebral hemisphere EXCEPT: Correct
Answer: Contralateral Subclavian Artery to the Internal Mammary Artery (This is
NOT a collateral pathway to the Cerebral hemisphere)
- Contralateral ICA thru reversed flow in Ipslateral ACA
- VB system thru the PCoA
- Ipslateral ECA thru the orbit to the Ophthalmic artery

Which branch of the ECA provides a collateral pathway to the Vertebral artery?
Correct Answer: Occipital*

In case of the Vertebral artery occlusion, which vessel is likely to be enlarged?
Correct Answer: Contralateral Vertebral!
(compensatory enlargement of the contralateral vertebral is common)

48 yr old male presents w/ retrograde flow in Lt Vertbral A. most likely related to
occlusion of the: Correct Answer: Lt Subclavian Artery*
-prox lt subclavian occlusion, lt VA flow will reverse to
-provide BF to the left arm
-condition termed SUBCLAVIAN STEAL***
-occurs more commonly on left side

What is the most common anomaly of the Circle of Willis? Correct Answer:
Absence of Hypoplasia of 1 or both communicating arteries

Which of the following is NOT a branch of the Subclavian Artery? Correct
Answer: NOT Brachial Artery
- vertebral/thyrocervical trunk/internal mammary artery

, Differentiation of the Cervical ICA from the ECA can be accomplished by all of
the following EXCEPT*: Correct Answer: ICA is usually located anteromedial to
the ECA
- ECA gives off multiple branches,
- ICA normally no branches, bulbous area seen at origin
- ICA usually located lateral and posterior to ECA

Which of the following vessels joins the Brachial Veins to form the Axillary
Vein*? Correct Answer: Superficial Basilic vein*
- begins at Ulnar side of forearm,
- crosses ventrally at Antecubital region
- lies medial to Brachial in upper arm

Which vein in the Antecubital Fossa connects the Cephalic and Basilic
(superficial) veins? Correct Answer: Median Cubital Vein (not paired)

All of the following are Deep Veins of Upper Extremity* EXCEPT: Correct
Answer: Cephalic (Superficial: Basilic, median cubital veins not paired)
- DEEP veins are Deep Palmar venous arch, Radial, Ulnar, interosseous veins of
forearm, Brachial, Axillary
usually paired deep veins*

Brachiocephalic VEIN is found: Correct Answer: on both sides of the neck
- formed by the junction of the Subclavian and Internal Jugular Veins

The longest vein in the body is the: Correct Answer: Greater Saphenous Vein
(GSV)*

Which of the following is NOT true regarding Perforating Veins*? Correct
Answer: Direct blood from the Deep system into Superficial system
- Perforating veins direct blood flow from Superficial system (GSV/LSV) into
Deep system
- has 1 valve each, more numerous in the calf than thigh, known as Varicose veins
when they are tortuous and dilated due to incompetent valves

Portal Vein* is formed by the junction of which of the following veins? Correct
Answer: - Splenic and SMV***

What vein normally courses b/n the SMA and Abdominal AO? Correct Answer:
Left Renal Vein*
