Chapter 1: Arterial Anatomy Flashcards
Where does the Radial Artery travel?
Lateral side of forearm into hand branching to form superficial palmar arch and terminates in deep palmar arch
Where does the Ulnar Artery travel?
Medial side of forearm into hand.
Deep palmar arch branch
Terminates in superficial palmar arch
Predominate source of blood flow to hand
What does the Superficial palmar arch include?
- Distal portion of Ulnar Artery
2. Branch of radial artery
What is the first branch of the ascending Aorta?
Coronary Artery
What does the Brachiocephalic Artery / Innominate Artery branch into?
Right CCA and Subclavian Artery
What is the second branch off of the aortic arch?
Left CCA
What is the third branch off of the aortic arch?
Subclavian Artery
What are the upper extremity arteries?
- Subclavian Art.
- Axillary Art.
- Brachial Art.
- Radial Art.
- Ulnar Art.
What does the deep palmar arch include?
Deep palmar branch of Ulnar Artery and distal portion of Radial Artery
What are the visceral branches off of the Abdominal aorta?
- Celiac Art.
- Superior Mesenteric Art. (SMA)
- Renal Arteries
- Inferior Mesenteric art. (IMA)
What does the Celiac Artery supply?
Stomach Liver Pancreas Duodenum Spleen
What does the celiac artery branch into?
Left gastric artery
Splenic Artery
Common hepatic arteries
What does the SMA supply?
Small intestine
Cecum
Parts of colon
What do the renal arteries supply?
Kidneys
Suprarenal glands
Ureters
What is the landmark for locating the left renal Artery?
Left renal vein which crosses the aorta anteriorly
What does the IMA supply?
Descending colon and part of cecum
What is the terminal branch off of the abdominal aorta?
Common iliac arteries (CIA)
What do the common iliac arteries supply blood to?
Pelvis
Abdominal wall
Lower limbs
What does the common iliac arteries divide into?
Internal iliac Artery (hypogastric)
External iliac Artery
Name the arteries in the lower extremity?
Common femoral Artery Popliteal Artery Anterior tibial Artery Posterior tibial Artery Perineal Artery
What does the CFA divide into?
Superficial femoral Artery Deep femoral (profunda femoris) Artery
What is the name of the opening the superficial femoral Artery passes through?
Adductor canal or Hunters canal
What is the adductor hiatus?
Termination of the SFA and beginning of popliteal Artery
What does the popliteal Artery divide into?
Anterior and posterior tibial arteries
What arteries are considered the “trifurcation”?
Anterior tibial arteries
Posterior tibial arteries
Peroneal arteries
What is the first branch off of the distal popliteal Artery?
Anterior tibial arteries
What does the anterior tibial arteries become at its lower end?
Dorsalis pedis Artery (DPA)
What is the major branch off the DPA?
Deep plantar Artery
What does the deep plantar Artery feed?
Penetrates sole of foot, unites with lateral plantar Artery to complete plantar arch
Where do the posterior tibial arteries course?
Posterior and medial side of leg
What is the tibioperoneal trunk?
Shirt segment of ATA branch and branches of PTA and peroneal arteries
What are the major branches off of the PTA?
Lateral and medial plantar arteries. Supplies sole of foot
What do the peroneal arteries supply?
Lateral side of foot/leg
What does plantar arch consist of?
Deep plantar Artery (branch off DPA)
What are Arterioles?
Considered resistance vessels; assist with regulating blood flow through contraction and relaxation
What are Capillaries?
Nutrients and waste products are exchanged between the tissue and blood
What are venules?
Collect blood from capillaries
What are the three layers that line arterial walls?
- Tunica intima (inner layer)
- Tunica media (middle layer)
- Tunica externa (adventitia)(outer layer)
What does the tunica adventitia layer contain within?
Vasa vorum; tiny vessels that carry blood to the walls of the larger arteries
