What are the parts of the axillary artery?
It has three branches that are variable in their order: the subscapular trunk, the anterior humeral circumflex artery, and the posterior humeral circumflex artery. The subscapular trunk is typically the largest branch of the axillary artery.
Where does the axillary artery begin?
The axillary artery starts from the lateral border of the first rib, as a direct continuation of the subclavian artery. It enters the axilla at the apex and crosses the first intercostal space to run along the lateral wall of the axilla.
How is the axillary artery divided?
The axillary artery is divided into three parts by its relation to pectoralis minor muscle: the first part is proximal to pectoralis minor. the second part is posterior to pectoralis minor. the third part is distal to pectoralis minor.
Where does axillary artery begin and end?
The axillary artery is a continuation of the subclavian artery that begins at the outer border of the first rib. It then courses through the axilla while being bordered by the lateral (superiorly), posterior (posteriorly), medial (inferiorly) cords of the brachial plexus and the ansa pectoralis (anteriorly).
What is the origin and termination of axillary artery?
Anatomical terminology In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
Where is the right axillary artery located?
In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
Is axillary anterior or posterior?
Bordered by the serratus anterior and the thoracic wall medially, a part of the humerus laterally, the pectoralis muscles anteriorly, together with the latissimus dorsi, but not only, posteriorly, the axilla is an important region, both in terms of neurovasculature and clinical relevance.
Where is the axillary vein?
The axillary vein is a major vein in the upper body that carries blood from the upper limb, armpit, and the upper side of the chest wall towards the heart.
What are the borders of the axilla?
There are five anatomic borders of the axilla: the superior, anterior, posterior, lateral, and medial walls. The medial wall is the serratus anterior and the first four ribs. The humerus, the coracobrachialis, and the short head of the biceps form the lateral wall.
What is the first branch of the popliteal artery?
Femoral artery
The popliteal artery is one of the major arteries of the leg. It is a continuation of the femoral artery, travels across the popliteal fossa, and finally bifurcates into the anterior and posterior tibial ends….Popliteal artery.

What is the first branch of the brachial artery?
profunda brachii artery
Deep brachial artery: Also called the profunda brachii artery, this is the first and main branch of the brachial artery. It supplies blood to parts of your humerus bone (long bone in your upper arm), deltoid muscle (rounded part of your shoulder) and triceps muscle (back of your upper arm).
What is the function of the axillary artery?
The axillary artery is a large muscular vessel that travels through the axilla. It is responsible for carrying oxygen-rich blood to the upper limb, as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax.
What does axillary artery mean?
The axillary artery is a large blood vessel that carries oxygenated blood to various parts of the upper body . These parts of the body include the thorax, upper limb, and axilla (more commonly known as the armpit).
Can the aorta artery be replaced?
Aortic valve surgery – open. If your aortic valve is too damaged, you will need a new valve. This is called replacement surgery. Your surgeon will remove your aortic valve and sew a new one into place. There are two main types of new valves: Mechanical, made of man-made materials, such as titanium or carbon. These valves last the longest.
What are the divisions of the axillary artery?
the first part is proximal to pectoralis minor
