Subclavian

What is origination of brachial artery

Axillary artery

Is radial or ulnar artery smaller

Radial

What does radial artery mainly supply

Deep palmer arch, RAD = radial arch is deep

What does ulnar artery maInly supply

Superficial Palmer arch, USA=ulnar superficial arch

Where do digital arteries arise from

Palmer arches

What branches from ascending aorta

Right and left coronary artery

Where does aortic arch become the abdominal aorta

When it passes through diaphragm

What are major branches of abd aorta

Celiac axis, SMA (right sided structures:intestines and colon), renal, IMA (left sided structures)

What branches from the celiac axis

Splenic artery, left gastric, common HA

What does the SMA feed

Small intestine, cecum, ascending colon 

What is the only vessel seen posterior to the IVC

Right Renal artery

Remember VAU

Where does the aorta terminate

At the Iliacs around L4, L5

What is internal iliac artery also called

Hypogastric artery

Is external or internal iliac artery larger

External

Where does common femoral artery begin

At termination of External iliac artery at inguinal ligament

What does CFA divide into

Superficial and deep femoral arteries 

What is another name for DFA

Profundity femoris

what artery is commonly used in TRAM or CABG procedures

inferior epigastric artery

where does the common femoral arise from

external iliac at inguinal ligament

what is adductor canal / Hunter’s canal

tunnel in which superficial femoral passes to popliteal fossa

what is another name for femoral triangle

scarpas triangle

what does SFA become

popliteal

what does pop become

anterior tibeal artery, tibioperoneal trunk (also known as trifurcation - trunk splits)

what is first branch of distal pop artery

anterior tibeal

what does anterior tibeal become

dorsalis pedis artery

what is second branch of distal pop artery

tibioperoneal trunk

what does tibioperoneal trunk branch to

posterior tibial and peroneal artery

what feeds the sole of the foot

medial and lateral planter artery (from post tib)

what does peroneal supply blood to

lat low leg, calcaneus/heel

what is plantar arch made up of

deep plantar artery anastomoses w/lateral plantar artery

what plays a major role for regulating blood flow

arterioles

what is outlayer of arteries

tunical adventitia, elastic lamina runs longitudinally (provides elasticity)

what is middle layer of arteries

tunica media, smooth muscle in circular pattern (controls diameter)

what is inner layer of arteries

tunica intima, endothelia cells provide smoothness in long pattern
