What are 3 branches of the thoracic aorta?
Typically, there are three branches arising from the aortic arch: the brachiocephalic trunk or artery (also referred to as the innominate artery), the left common carotid artery, and the left subclavian artery.
What are the 5 sections of the aorta?
The abdominal aorta runs from the diaphragm and ends just above the pelvis, where it divides into the iliac arteries. There are five arteries that branch from the abdominal aorta: the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.
What is the anatomy of the aorta?
The aorta is a cane-shaped artery. It starts in the lower-left chamber of your heart (ventricle). From there, it extends up toward your head a short distance before curving down. The aorta passes through your chest and abdominal cavities and ends at your pelvis.
What are the two types of aortic dissection?
In the DeBakey classification of aortic dissection: Type I involves the ascending aorta, arch, and descending thoracic aorta and may progress to involve the abdominal aorta. Type II is confined to the ascending aorta.
How do you remember the branches of the thoracic aorta?
​Mnemonic
- A: arch of aorta.
- B: brachiocephalic trunk.
- C: left common carotid artery.
- S: left subclavian artery.
What is the first branch of the aorta?
brachiocephalic trunk
The first branch of the aorta is normally the innominate artery, which is also referred to as the brachiocephalic trunk. Shortly after its origin, the innominate artery divides into the right subclavian and right common carotid arteries.
How can you tell the difference between a Type A and B aortic dissection?
Type A which is the more common and dangerous of the two and involves a tear in the part of the aorta where it exits the heart or a tear in the upper, or ascending aorta, which may extend into the abdomen. Type B which involves a tear in the lower, or descending, aorta only, which may also extend into the abdomen.
What is the first artery to branch off the aorta?
brachiocephalic artery
The ascending aorta ends right before the brachiocephalic artery, which is the first branch off the aortic arch.
What is the second artery that branches off the aortic arch?
The suprarenal artery is the second branch from the abdominal aorta.
What are the 6 aortic arches?
| Arch | Vessel |
|---|---|
| 4th Aortic sac | R: Right subclavian artery L: Aortic arch Brachiocephalic artery (divides into right subclavian and right common carotid artery) |
| 5th | R: Right pulmonary artery (proximal part) L: Ductus arteriosus |
| 6th Intersegmental artery | Left pulmonary artery |
What are the two branches of the ascending aorta?
The ascending aorta has two small branches, the left and right coronary arteries. These arteries provide blood to the heart muscle, and their blockage is the cause myocardial infarctions or heart attacks.
