The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.
Where does the brachiocephalic artery take blood?
The Anatomy of the Brachiocephalic Artery
It feeds blood flow to the right carotid artery and the right subclavian artery. It is also known as the innominate artery or the brachiocephalic trunk. The name refers to the fact that blood flows through this very short artery to the arm (brachio) and the head (cephalic).
What are the two main branches of brachiocephalic artery?
It is the first branch of the aortic arch. Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
Why is there only one Brachiocephalic artery?
From the picture we can see arch of aorta has three branches : brachiocephalic artery, left common carotid artery and left subclavian artery. … Whereas in the left side, the left common carotid artery and the left subclavian artery arises directly from the arch of aorta. So, there is no left brachiocephalic artery.
How many Brachiocephalic trunks are there?
The normal aortic arch branches into three, the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. After a short superior course, the brachiocephalic artery then divides into the right subclavian and right common carotid arteries.
What organ does the brachiocephalic artery supply?
The brachiocephalic trunk (or brachiocephalic artery or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.
What is the largest artery in the body?
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is the function of the carotid artery?
The internal carotid artery, being one of the most clinically relevant and vital arteries, supplies oxygenated blood to crucial structures such as the brain and eyes.
Which artery is on right side only?
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left.
How many brachiocephalic veins are there?
The two brachiocephalic veins merge together with the azygous vein, which carries deoxygenated blood from the rib cage, to form the superior vena cava. The blood that flows into the heart from the superior vena cava is controlled by the contractions of the heart.
What comes off Brachiocephalic trunk?
The brachiocephalic trunk gives off the right subclavian artery, supplying the right upper limb; and the right common carotid artery, supplying the right side of the brain, head and neck.
Is there a right and left brachiocephalic vein?
Structure and Function
The brachiocephalic veins are formed by the confluence of the subclavian vein and internal jugular vein, on the right and left, respectively. The brachiocephalic veins, as well as the vena cava, are valveless vessels.
Where is the innominate artery located?
Brachiocepahlic Artery (Innominate Artery )
Longest branch of the arch ( 4-5 cm long). It ends by dividing into the right common carotid artery and right subclavian artery at the upper border of right sternoclavicular junction. Usually devoid of branches.
What does Brachiocephalic mean?
relating to the arm and head, used when referring to blood vessels that supply blood to the head, neck, and arms.
Where does the subclavian artery carry blood to?
They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax.
