Arteries Flashcards
- the main arterial trunk of the systemic circulation divided into:
o Ascending aorta
o Arch of aorta
o Descending/ Thoracic Aorta
o Abdominal aorta
Aorta
➢ Coronary arteries arise: – blood supply
➢ Right coronary from anterior aortic sinus
➢ Left coronary from left posterior aortic sinus
Ascending aorta
➢ direct branches:
▪ brachiocephalic or innominate artery – supplies blood to the right arm and the head and neck.
▪ left common carotid
▪ left subclavian
Arch of aorta
➢ Begins at level of T4 and descends to diaphragm to become abdominal aorta
Descending/ Thoracic Aorta
Visceral :
o Paired
➢ Suprarenal arteries
➢ Renal artery
➢ Gonadal artery
o Unpaired (Single)
➢ Celiac artery
➢ Superior mesenteric artery
➢ Inferior mesenteric artery
➢ Continuation of thoracic aorta
➢ passes through diaphragm at level of T12
Abdominal aorta
supplies kidney
Renal artery
supplies suprarenal gland
Suprarenal arteries
going to the testicular or ovarian
Gonadal artery
supplies foregut
Celiac artery
supplies midgut
Superior mesenteric artery
supplies hindgut
Inferior mesenteric artery
Parietal :
o Paired
➢ Inferior phrenic
➢ Lumbar
o Unpaired (Single)
➢ Median sacral
supplies lower diaphragm
Inferior phrenic
supplies posterior abdominal wall
Lumbar
supplies the inferior vertebrae
Median sacral
Common carotid arteries :
- External carotid artery
- Internal carotid artery
➢ That will supply blood to the face and neck.
- External carotid artery
➢ Will go inside the brain to form the blood supply for the brain called Circle of Willis
Internal carotid artery
Blood supply of the Brain (Circle of Willis) :
- Internal carotid artery
- Vertebral artery
Arteries of the Upper Limbs
- Axillary artery
- Brachial artery
- Radial artery
- Ulnar artery
Coming from the subclavian artery
Axillary artery
coming from the axillary artery.
Brachial artery
terminal branch of the brachial artery and arises at the cubital fossa of the forearm.
Radial artery
also a terminal branch of brachial artery and arising at the proximal aspect of the forearm
Ulnar artery
Arteries of the Lower Limbs
o Femoral artery
- a. Anterior tibial artery
- b. Posterior tibial artery
becomes the popliteal artery that divides into:
a. Anterior tibial artery
b. Posterior tibial artery
Femoral artery
➢ continues as dorsalis pedis
Anterior tibial artery
➢ divides into medial and lateral plantar arteries
➢ back of the knee – popliteal artery
Posterior tibial artery
NEVER BACK DOWWN NEVER WHAT!!!!!!!!!!!!!!!!!!!!????????????????
NEVER GIVE UP!!!!!!!!!!!!!!!!!!!!!!!!!!
