Chapter 1. Arterial Gross Anatomy Flashcards
Proximal to the Aortic Arch, what are the first branches of the ascending aorta?
Rt and Lt Coronary Arteries.
Name the 3 branches of the Aortic Arch?
Innominate/Brachiocephalic, Lt Common Carotid Artery, and the Lt Subclavian Artery.
The Brachiocephalic artery divides into which arteries?
Rt Common Carotid Artery, and the Rt Subclavian Artery
The Subclavian artery run laterally to outer border of the 1st rib to become which artery?
Axillary Artery
This artery travels down the lateral side of the forearm into the hand, branching to form the superficial palmar (volar) arch?
Radial Artery
This artery terminates in the deep palmar arch by joining the deep branch of the ulnar artery?
Radial Artery
Which artery is the predominate source of blood flow to the hand?
Ulnar Artery
The Deep palmar arch includes the deep palmar branch of what artery?
Ulnar Artery
The celiac artery supplies what?
stomach, liver pancreas, duodenum, spleen.
The celiac artery branches into which arteries?
Lt Gastric, Splenic, and Common Hepatic Artery.
The Superior Mesenteric Artery (SMA) supplies what?
Small intestine, cecum, and parts of the colon.
The inferior mesenteric artery (IMA) supplies what?
transverse, descending colon and part of the rectum.
Which artery arises from the abdominal aorta about 3-4 cm above the bifurcation?
IMA- Inferior Mesenteric Artery
What are the terminal branches of the abdominal aorta?
Common Iliac Arteries.
This artery runs the length of the thigh , passing through an opening in the tendon of the adductor hiatus (adductor canal, or Hunter’s canal)
Superficial femoral artery.
The Common femoral artery divides into which arteries?
SFA and DFA (profunda)
What is the first branch off of the distal popliteal artery?
Anterior tibial artery. ATA
At its lower end the ATA becomes which artery?
Dorsalis Pedis Artery (DPA)
This major branch of the dorsalis pedis artery, penetrates the sole of the foot, it unites with lateral plantar artery to complete the plantar arch.
Deep plantar artery.
What are the major branches of the Posterior tibial artery?
Lateral and Medial plantar arteries.
These are considered resistance vessels; assist with regulating blood flow through contraction and relaxation.
Arterioles.
This layer of the arterial wall is thin, consisting of a surface layer of smooth endothelium, base membrane and connective tissue.
Tunica intima.
this layer of the arterial wall is thicker, composed of smooth muscle and connective tissue, largely of the elastic type.
Tunice Media
This layer of the arterial wall is somewhat thinner than media, contains fibrous connective tissue; some muscle fibers
Tunica externa (adventitia)
