arteries

off of aortic arch

brachiocephalic, left common carotid, left subclavian

off of brachiocephalic

right common carotid and right subclavian

right common carotid divides into

right and left external carotids

right internal carotid divides into

right anterior cerebral artery and right middle cerebral artery

off of right subclavian

right vertebral and axillary

off of left common carotid

left external and internal carotid

left subclavian

left vertebral and axillary

the branches off the external carotid artery

Maxillary - supplies upper and lower jaw

Occipital - supplies psoterior scalp

Facial - supples skin and muscles of the anterior face

Linguinal - supplies tongue

Superior thyroid - supplies thyroid and larynx

the vessels of the Circle of Willis

- Right vertebral artery joins with left vertebral artery to form the basilar artery

- Basilar artery divides into the right and left cerebral arteries: upply occipital and inferior temporal lobes of brain

- Middle cerebral arteries branch off of internal carotids - supplies to lateral parts of temporal and parietal lobes

- Internal carotids break form anterior cerebral arteries - supplies to medial surface of brain

- Anterior communicating artery connects right and left anterior cerebral arteries

- Posterior communicating artery connects internal carotids to posterior cerebral arteries

the branches off the axillary artery

- subclavian artery becomes axillary artery when it passes under clavicle

- Branches:

Thoracoacromial - supplies superior shoulder and pectoral region

Lateral thoracic - supplies lateral chest wall and breast

Subscapular - supplies scapula, latissimus dorsi and thorax wall

Anterior and posterior circumflex arteries - supply deltoid and shoulder joint

branches off of the right subclavian artery

- internal thoracic artery

- Gives rise to anterior intercostals as it descends - supplies anterior intercostal spaces

off of the internal thoracic (off of left subclavian)

- Costocervical

- Gives rise to the first two posterior intercostal arteries

- Thoracic artery gives rise to the next nine posterior intercostal arteries

- Supplies posterior intercostal spaces and deep muscles of back, vertebral columns and spinal cord

the branches off the abdominal aorta (below diaphragm)

Phrenic arteries supply the diaphragm

Gives rise to celiac trunk

Adrenal: supply adrenal glands

Superior messenteric: large intestine and colon

Renal: supply kidney

Gonadal: supply gonads

Inferior mesenteric: supply colon

Lumbar arteries: supply posterior abdominal wall

Terminates and gives rise to the right and left common iliacs and median sacral

the branches off the celiac trunk

- Comes off of abdominal aorta

common hepatic

splenic

left gastric

off of common hepatic

Common hepatic

Gives off branches to stomach, small intestine and pancreas

Becomes hepatic artery- Right and left branches, Supplies liver

off of Splenic

Sends branches to stomach and pancreas

Splenic terminates in the spleen

Left gastric

Supplies stomach and inferior and esophagus

Internal iliac

supplies plevis, bladder, rectum, uterus and vagina

External iliac

becomes femoral

Femoral artery

Branches off into deep femoral

Femoral continues to descend and enters popliteal fossa

Becomes politeal artery

deep femoral

Supplies posterior thigh

popliteal artery

Supplies knee region

Divides into anterior tibial, posterior tibial, and fibular (posterior)

brachial branches

- axillary becomes brachial once it enters arm

- Supplies anterior arm

Branches:

Deep brachial artery supplies posterior arm

Radial artery supplies lateral muscles of forearm

Ulnar artery supplies medial muscles of the foreaerm
