Week 3 (9/8) Arteries

ascending aorta

the “left side” of the aortic arch, coming up directly from the heart

r. and l. coronary arteries

thin artery coming off of either side of the ascending aorta, attached to the heart

aortic arch

the distinctive arch above the heart, with the descending aorta on the left side and ascending aorta on the right

brachiocephalic trunk

left branch off the top of the aortic arch, prior to branching

r. common carotid artery

comes off of the brachiocephalic trunk, ascends up the neck bordering the trachea

r. subclavian artery

branches off the brachiocephalic trunk at the same point as the right carotid artery

l. common carotid artery

middle branch off the aortic arch, going up into the neck bordering the trachea

l. subclavian artery

rightmost branch off the aortic arch, moving into the clavicle

thoracic aorta

part of the descending aorta above the diaphragm

abdominal aorta

part of the descending aorta below the diaphragm

celiac trunk

distinctive branch off the descending aorta, going out to form the hepatic artery and splenic artery

splenic artery

righter branch off the celiac trunk, serving the pancreas and spleen

common hepatic artery

lefter branch off the celiac trunk, serving the liver

left gastric artery

branches off near the top of the celiac trunk, following near the top of the stomach

superior mesenteric artery

thick branch off the descenidng aorta underneath the celiac trunk, sevring the small intestine

r. and l. suprarenal arteries

small arteries serving the adrenal glands from the top, middle, and bottom

r. and l. renal arteries

branch into the middle of the kidney, around the level of the superior mesenteric

r. and l. testicular/ovarian arteries

branches from the descending aorta on either side, superior to the inferior mesenteric artery

inferior mesenteric artery

large artery that splits off (only one) from the descending aorta just superior to the split of the common iliac artery

r. and l. common iliac arteries

descending/abdominal aorta splits off into two large arteries around the coccyx

external carotid artery

splits off either side of the common carotid arteries, supplying blood to the sueprficial face and neck

internal carotid

smaller split off the side of either common carotid artery, supplying blood to the brain

r. and l. vertebral arteries

splits off either side of the subclavian artery, more right/left than the common carotid branch. extends deeper into the spinal area, the bottom “tails” of the circle of willis

r. and l. middle cerebral artery

located towards the “middle” of the circular part of the circle of willis on either side, but branching OUT

r. and l. anterior cerebral artery

extends “up” toward the frontal lobe/anterior aspect of the brain at the level of the anterior communicating artery

anterior communicating artery

small horizontal artery between the anterior cerebral arteries, near the top of the circle of willis

basilar artery

either side of the vertebral arteries appear to “converge” to the middle at the base of the circle of willis

r. and l. posterior cerebral artery

curves up and over on either side at the top of the basilar artery

r. and l. posterior communicating artery

form the bottom sides of the circle of willis, thinly branching off the apex curve of the posterior cerebral arteries

axillary artery

after the subclavian artery passes the clavicle

brachial artery

after the axillary artery passes the armpit area

radial artery

splits off the brachial artery at the level of the elbow, follows to the radial/thumb side

ulnar artery

splits off the brachial artery at the level of the elbow, follows to the ulnar/pinkie

superficial palmar arch

arching artery in a loop, appearing closer to the knuckles and one side of the loop coming off the side of the ulnar artery

deep palmar arch

arching artery in a loop, deeper in the aspect of the hand and closer to the mass of the carpals

r. and l. internal iliac arteries

thin artery splitting off the common iliac artery, descending into the pelvic bone

r. and l. external iliac arteries

appears to be the continuation of the common iliac artery after the level of branching at the internal iliac artery

femoral artery

the external iliac artery is called this after it passes the level of the inguinal ligament

popliteal artery

the femoral artery is called this once it reaches the knee area and goes to the posterior side

anterior tibial artery

the branch of the popliteal artery that extends forward through the knee to supply the anterior aspect of the calf

dorsalis pedis artery

splits off the anterior tibial artery near the level of the ankle and stays medial, forming one side of the arcuate arch

arcuate artery

thin horizontal artery whose branches go on to supply the metatarsals

posterior tibial artery

branch of the poplieal artery that stays on the posterior aspect and follows the tibia (medial side)

fibular artery

bracnh of the popliteal artery that says on the posterior aspect and follows the fibula (lateral side)

medial plantar artery

branch of the posterior tibial artery extending to the “underside” of the foot (or the plantar surface) on the medial side

lateral plantar artery

branch of the posterior tibial artery extending to the “underside” of the foot (or the plantar surface) on the lateral side
