Davies Vascular Technology Review The first major arterial branch of the Aorta is the: - Innominate Artery Which of the following arteries does NOT arise from the Subclavian Artery? - Superior Thyroid The angular artery is the terminal part of the: - Facial artery The arterial pulsations felt in front of the ear and just above the zygomatic arch are from which artery? - Superficial Temporal The CCA divides into its external and internal branches usually at the level of the upper border of the: - Thyroid cartilage What artery is usally the first branch of the ECA - Superior thyroid artery Which of the following is not an artery in the circle of Willis? - Middle communicating artery Which of the following arteries arise(s) from the ECA? - All - superior thyroid - lingual - facial - ascending pharyngeal The prominence of the larynx is form by the - Thyroid cartilage (thyroid cartilage forms a prominenc that is especially visible in tall, thin, socially awkward males) The Vertebral artery usually arises from the: - Subclavain artery The infraOrbital artery is a terminal branch of the: - Maxillary artery (infraorbital artery is a terminal branch of the maxillary artery. It creates one of the potential anastomoses w/ orbital branches that can provide collateral path ways in the event of carotid obstruction) The vertebral arteries branch from the Subclavian arteries to unite and form the: - Basilar artery The first intracranial branch of the ICA is the: - Ophthalmic artery The circle of Willis receives its blood supply from which combination of arteries? - Carotid and Vertebral arteries* ( remarkable connection of carotid and vertebral arteries: makes possible the ability of the brain to withstand extracranial carotid occlus ion w/o significant symptoms) The 3 terminal branches of the Opthalmic artery are the: - Nasal, Frontal and Supraorbital arteries 2 of the major branches of the ECA include the: - Superficial temporal and facial arteries Intracranial potential collatera l arteries include all but the following: - Superficial temporal artery Which of the following is NOT true regarding the ICA? - It supplies high -resistance system is false! (ICA feeds low -resistance system) The 2 arteries creating the bidirectional signa l observed 60 -65 mm deep during transcranial insonation of the temporal window are the: - Middle cerebral and ANTERIOR cerebral arteries* What is the most common anomaly of the Circle of Willis? - Absence or Hypoplasia of 1 or both of the communicating ar teries Matching: Proximal vessel: Branch or Continuation of Vessel: A. Innominate 1. ICA B. Subclavian 2. Subclavian C. CCA 3. Basilar D. Vertebral 4. Superficial Temporal E. ECA 5. Vertebral - A. Innominate 2. Subclavian B. Subclavian 5. Vertebral C. CC A 1. ICA D. Vertebral 3. Basilar E. ECA 4. Superficial Temporal Helical flow w/ flow separation in the posterolateral aspect of the carotid bulb is a sign of: - Normal flow dynamics The most common anatomic variant of the aortic arch is: - A common origin of the innominate and Lt CCA The Greater Saphenous Vein: - All - originates along the medial dorsum of the foot - passes superiorly, anterior to the medial malleolous - is accompani ed by the saphenous nerve - receives tributaries from all surfaces of the lower extremity Which of the following is NOT correct regarding the GSV? - It passes superiorly on the "Lateral" side of the knee is false. - it passes superiorly on the medial side of the thigh - it enters the femoral vein - it extends distally to the dorsum of the foot - it has more valves in the calf thaan in the thigh The superficial vein that sends flow to the 3 main perforating veins of the distal calf is called: - Posterior A rch vein* (it connects the Cockett perfs in the calf, is implicated in the formation of venous stasis ULCERS) Boyd's perforating vein is located: - NEAR the KNEE* *Main ones are Cockett perfs in the mid -distal calf connected by posterior arch vein; Boyd' s perfs near the medial Knee, Dodd's perfs above the knee; Hunter's perfs around mid thigh The Left Common iliac vein: - Crosses POSTERIOR to the rt common iliac artery just distal to the Ao bifurcation - LT Common Iliac Vein is medial to the artery, T he vena cava is to the RT of the AO, thus the Left venous system must cross some arterial structure to communicate w/ the Vena Cava! From this cross -sectional diagrahm of the thigh, reading from superficial to deep, identify the vessels marked: - GSV, SFV, PFV* image The brachial veins connect the: - Ulnar & radial to brachial to Axillary veins* Of the following vein segments, which i s imaged LEAST commonly? - Distal DFV -BC of its depth, the distal deep femoral vein is usually very difficult to image The term MUSCLE PUMP refers to: - The calf muscles In this cross section of the calf, which letter represents the Posterior Tibial Ve ssels? - E PTV next to Peroneal veins by GSV - A Peroneal - B LSV - C ATV - D GSV In this cross section of the calf, which letter represents the Fibula? - C Fibula, smaller bone next to Peroneal veins - D Tibia In this cross section of the calf, which le tter represents the Interosseous membrane? - E Interosseous septum - next to ATV, Btn Tibia & Fibula In this cross section of the calf, which letter represents the Lesser Saphenous Vein? - B LSV smaller of the superficial vein below peroneal, fibula iden tify which is anterior and which is lateral Which vein in the Antecubital Fossa connects the Cephalic and Basilic veins? - Median cubital vein Which of the following is NOT a Deep vein of the upper extremity? - Cephalic vein The Brachiocephalic vein is found: - On both the right and left Which of the following vessels joins the Brachial Veins to form the Axillary vein? - Basilic vein** Muscular veins of the calf that empty into the Popliteal vein behind the knees are: - Gast rocnemius veins Compared to the arteries, veins have: - Thinner ADVENTITIA & MEDIA intima are the same size in arteries and veins Regarding venous valves, which is FALSE? - allow flow only away from the heart - allows flow TOWARD heart Peripheral resis tance increases with: - Greater length, smaller diameter, higher blood viscosity** (Poiseuille's resistance equation demonstrates influences on resistance of length, viscosity and (inversely & powerful) RADIUS) The following arteries have LOW resistance flow character: - ICA, POSTprandial SMA, Renal arteries*** - after meal sma flows have lower resistance, higher diastolic flow Which of the following statements about the Dorsalis Pedis Artery is NOT correct? - It is a branch of the peroneal artery is fal se - runs anterior to the medial malleolus - is typically the continuation of the ATA - joins the pedal arch about 1/2 way along dorsum of foot - begins at the bend of the foot & ankle ( Dorsalis pedis continues the ATA to the pedal arch)** Vessels and st ructures of the Penis include all of the following EXCEPT: - Inferior Vesicle arteryThe benefits of buying summaries with Stuvia:
