Arterial Anatomy Flashcards
First branches proximal to ao arch
coronary arteries
Some branches of subclavian artery
vertebral, thyrocervical, costocervical
artery that runs laterally to outer boarder of 1st rib
subclavian
Radial artery branches to form
superficial palmar (volar) arch terminates in deep palmar arch by joining deep branch of ulnar artery.
Ulnar artery branches to form
deep palmar (volar) branch terminates in superficial palmar arch
Predominate source of blood flow to the hand is from what artery?
Ulnar
What arteries does the superficial palmar arch include?
distal portion of the ulnar artery
branch of the radial artery
What arteries does the deep palmar arch include?
Deep palmar branch of ulnar artery
Distal portion of the radial artery
Digital arteries arise from what arteries and extend into the fingers dividing into lateral and medial branches?
palmar arches
What organs does the celiac artery supply?
stomach, liver, pancreas, duodenum, spleen
Branches of the celiac?
left gastric, splenic, and common hepatic arteries
What organs does the SMA supply?
small intestine, cecum, parts of colon
Renal arteries not only supply blood to kidneys but also to?
suprarenal glands and ureters
IMA supplies what organs?
transverse colon, descending colon, and part of the rectum
What aorta vessel arises 3-4cm above the bifurcation and can act as a collateral connection?
IMA
What region are the internal iliac arteries considered to be in?
hypogastric
course of the external iliac artery
medial side of psoas major muscle
external iliac becomes the common femoral artery once it passes where?
under the inguinal ligament
the superficial femoral artery passes through what canal?
adductor canal or hunters canal; passes through an opening in the tendon of the adductor hiatus
Another name for the deep femoral artery
profunda femoris
A large branch that arises 5 cm from the inguinal ligament on the lateral side. Can act as a collateral connection.
Deep femoral artery
where does the SFA terminate and the popliteal artery begin?
adductor hiatus (hunters canal)
what leg artery gives off a number of genicular branches to supply muscles, knee joint, and skin?
popliteal artery
at the interval of the tibia and fibula, the popliteal divides into what arteries?
anterior and posterior tibials
What leg arteries are referred to as the trifurcation?
ATA, PTA, and peroneals
First branch off the distal popliteal artery?
anterior tibial
ATA becomes what artery?
Dorsalis pedis artery
Major branch of the DPA, penetrates the sole of the foot and unites with lateral plantar artery to complete the plantar arch.
deep plantar artery
Short segment between ATA branch and branches of PTA and peroneal arteries?
Tibioperoneal trunk
PT’s extend obliquely down posterior/medial side of leg. What are the major branches?
Lateral and medial plantar arteries. Branch below medial malleolus to supply sole of foot.
Artery travels adjacent to the medial side of fibula to supply structures of the lateral side of leg/foot.
peroneals
What arteries distribute blood to the digits?
plantar and dorsal metatarsals
What are arterioles considered?
Resistance vessels. Assist in regulating blood flow through contraction and relaxation.
Capillaries exchange what between tissue and blood?
nutrients and waste products
What layer of the arterial wall contains the vasa vasorum, tiny vessels that carry blood to the walls of the larger arteries?
the adventitial (outer) layer
