Are brachiocephalic and innominate artery the same?
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.
What does innominate artery mean?
brachiocephalic artery
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.
Is there a left innominate artery?
The left innominate artery originated from a prominent divertic- ulum of Kommerell off the proximal descending aorta and bifurcated into the left subclavian and left common carotid arteries (Figure 1). The trachea was not compressed.
Why is there no left 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.
Is there only one brachiocephalic artery?
It is the first branch of the aortic arch, and soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. There is no brachiocephalic artery for the left side of the body. However, there are two brachiocephalic veins.
What is the brachial artery?
The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery courses along the ventral surface of the arm and gives rise to multiple smaller branching arteries before reaching the cubital fossa.
Where is the innominate vein?
thorax
The brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.
Where does the brachiocephalic artery bifurcate?
right sternoclavicular joint
The brachiocephalic trunk (BCT), also known as the “anonymous artery” constitutes the first branch of the aortic arch that bifurcates at the level of the right sternoclavicular joint into the RCCA and the RSA.
Where is the brachiocephalic artery?
mediastinum
The brachiocephalic trunk, also called the brachiocephalic or innominate artery, is the second branch to arise from the aorta. It courses upwards from the aortic arch through the superior mediastinum, until it reaches the right sternoclavicular joint, where it divides into its final branches.
What is profunda Brachii?
The profunda brachii artery also referred to as the deep brachial artery, is the first and largest branch of the brachial artery. It originates from the posterior portion of the brachial artery, just inferior to the lower border of the teres major muscle.
What does innominate vein mean?
Noun. 1. innominate vein – veins formed by the union of the internal jugular and subclavian veins. brachiocephalic vein, vena brachiocephalica. vein, vena, venous blood vessel – a blood vessel that carries blood from the capillaries toward the heart; “all veins except the pulmonary vein carry unaerated blood”
• INNOMINATE ARTERY (noun) The noun INNOMINATE ARTERY has 1 sense: 1. a large artery arising from the arch of the aorta and divides into the right subclavian artery and the right common carotid artery; supplies the right side of the neck and head and the right shoulder and arm. Familiarity information: INNOMINATE ARTERY used as a noun is very rare.
innominate vein (brachiocephalic vein) n. either of two veins, one on each side of the neck, formed by the junction of the external jugular and subclavian veins.
Is inferior vena cava an artery?
These veins drain blood from the upper body regions including the head, neck, and chest. It is bordered by heart structures such as the aorta and pulmonary artery. Inferior Vena Cava. The inferior vena cava is formed by the joining of the common iliac veins which meet a little below the small of the back.
What is the brachiocephalic trunk?
The brachiocephalic trunk is the first of the three main branches of the aortic arch, which originates from the upward convexity. It measures 4-5 cm in length with a diameter of 12.1 ± 1.6 mm.
