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.

How do you divide an axillary artery for descriptive purpose?

The pectoralis minor muscle crosses anteriorly axillary artery and, for purposes of description, is said to divide it into three parts anatomically: the first part of axillary artery is before the upper border, the second part is the behind and the third part of axillary artery is after the lower border of pectoralis …

How do you expose axillary arteries?

The axillary artery, which lies superior and posterior to the vein, can be identified by palpation and then exposed using sharp dissection. The exposure can be improved by one or two self-retaining retractors and by gentle downward axillary vein traction. The pectoralis minor is retracted or divided.

Which is the largest branch of axillary artery?

subscapular trunk
The subscapular trunk is typically the largest branch of the axillary artery. It gives rise to the scapular circumflex artery and the thoracodorsal artery. The scapular circumflex artery runs through the triangular space and provides blood to the scapular region.

Why is the axillary artery important?

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 muscles does axillary artery supply?

• trapezius muscle.
• latissimus dorsi muscle.
• levator scapulae muscle.
• rhomboid minor muscle.
• rhomboid major muscle.
• pectoralis major muscle.
• pectoralis minor muscle.
• serratus anterior muscle.

What major artery is under the arm?

Brachial Artery: This artery begins under the pectoralis muscle and travels down the arm. It eventually splits into two arteries (the radial artery and the ulnar artery) at the elbow.

Is there a major artery under your armpit?

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.

How do you know if you hit an artery instead of a vein?

Arteries have a pulse, and the blood in them is bright red and frothy. Arteries are located deeper in the body than veins and so are not visible as many of your veins are. You’ll know you hit an artery if: The plunger of your syringe is forced back by the pressure of the blood.

What happens if you cut the axillary artery?

Conclusions: Blunt trauma to a subclavian or axillary artery is associated with significant immediate morbidity and mortality. In the long-term, associated brachial plexus lesions plague most patients, who are left with a severe disability of the upper limb, which complicates their return to society.

Why is there a vein under my armpit?

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.

Where does the axillary artery cross the anterior wall?

Axillary Artery. In axilla, it runs from apex to the base along the lateral wall nearer to the anterior wall in relation to the posterior wall. During it’s course via axilla, it is crossed on it’s superficial aspect by the pectoralis minor muscle, which divides it into 3 parts.

Can a axillary artery be clamped without endangering the arm?

The axillary artery can be safely clamped without endangering the arm, but only in a location proximal to the origin of the subscapular artery (and distal to the thyrocervical trunk of the subclavian artery).

How is the axillary artery related to pectoralis minor?

The axillary artery is divided into three parts by its relation to pectoralis minor: 1 the first part is proximal to pectoralis minor. 2 the second part is posterior to pectoralis minor. 3 the third part is distal to pectoralis minor.
