Where does the axillary artery start 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 does the axillary artery split?

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.

What does the axillary artery turn into?

vessels become known as the axillary artery; this, in turn, becomes the brachial artery as it passes down the upper arm. At about the level of the elbow, the brachial artery divides into two terminal branches, the radial and ulnar arteries, the radial passing downward on the distal (thumb) side…

Where is the third part of the axillary artery?

The third part lies distal to the lower border of the pectoralis minor muscle, anterior to the subscapularis muscle and teres major muscle. It has three branches that are variable in their order: the subscapular trunk, the anterior humeral circumflex artery, and the posterior humeral circumflex artery.

Is axillary anterior or posterior?

The axillary apex is the interval between the superior border of the scapula, the posterior border of the clavicle, and the external border of the first rib. The pectoralis major and the latissimus dorsi form the major anterior and posterior folds, respectively, of the axilla.

Is there an axillary artery?

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 the axillary vein end?

Termination. The axillary vein terminates by becoming continuous with the subclavian vein at the lateral border of the first rib 2.

Where is the axillary vein?

Location. The axillary vein arises at the lower border of the axilla, just beneath the teres major shoulder muscle, near where the underarm meets the body.

Where is the radial artery located?

The radial artery runs on the inside of the forearm from the elbow to the thumb. The artery lies just under the surface of the skin. You may be able to see the blue or purple vein inside your wrist where the artery brings blood to the thumb.

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.

What artery is under the armpit?

Axillary Artery: This is a continuation of the subclavian artery. This artery travels deep in the arm pit, feeding muscles and bones around the shoulder with its branches. It eventually turns into the brachial artery.
