What is lateral thoracic artery?

The lateral thoracic artery supplies the axillary lymph nodes, serratus anterior, pectoralis major, pectoralis minor and subscapularis muscles. Additionally, it can provide blood supply to the breast in females.

Where is the lateral thoracic located?

The lateral thoracic artery originates from the medial surface of the axillary artery, posterior to the distal part of pectoralis minor. It courses inferomedially along the inferior border of pectoralis minor to the anterior surface of serratus anterior.

Does Thoracodorsal artery supply the breast?

The blood supply to the breast comes from perforating branches of the internal mammary, lateral thoracic, thoracodorsal, thoracoacromial, and intercostal arteries and veins18 (Fig. 13.1).

What does the axillary artery become?

While exiting the axilla, the axillary artery changes its name at the lower border of teres major and continues in the arm as the brachial artery. As soon as it exits the axilla, the axillary artery continues as the brachial artery.

What nerve runs with the lateral thoracic artery?

The long thoracic nerve (respiratory nerve of Bell) originates from roots C5, C6, and C7 of the brachial plexus and provides motor stimulation to the serratus anterior muscle. It usually can be found adjacent to the lateral thoracic artery’s origin and runs along the serratus anterior.

What does the radial artery do?

The radial artery is a blood vessel that supplies blood to the forearm (lower part of the arm) and hand. Arteries carry blood out to the body. This blood is oxygenated (carrying oxygen from your lungs to other body parts).

What nerve runs with lateral thoracic artery?

Where is your right thoracic artery?

It travels downward on the inside of the rib cage, approximately 1 cm from the sides of the sternum, and thus medial to the nipple. It is accompanied by the internal thoracic vein. It runs deep to the abdominal external oblique muscle, but superficial to the vagus nerve.

Where does lateral thoracic artery come from?

The lateral thoracic artery, which also arises from the second part of the axillary artery, follows the lateral border of the pectoralis minor muscle and supplies the lateral part of the pectoralis major muscle.

What is the lateral part of the breast?

At the lateral edges of the breast, the tail of Spence extends in the axilla. The underlying breast is made of glandular (milk-producing) and fatty tissue. The ratio of fat versus glandular varies depending on age, post-menopausal, post-partum, or pregnancy status.

What is the axillary artery a continuation of?

subclavian artery
The axillary artery represents the continuation of the subclavian artery and is a major artery of the upper limb.

Where does the axillary artery originate?

The axillary artery is the main artery of the upper extremity and originates as a continuation of the subclavian artery at the lateral margin of the first rib. The artery has six primary branches and is divided into three parts based on its relation to the pectoralis minor muscle (Fig. 27-7).
