Where does the lateral thoracic artery supply blood to?
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. This article will discuss the anatomy and function of the lateral thoracic artery.
What muscle does lateral thoracic artery supply?
pectoralis major muscle
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.
Where is the lateral artery located?
It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary lymph nodes and Subscapularis muscle.
What does the left internal thoracic artery supply?
The internal thoracic artery, aka the internal mammary artery, supplies the breast and the anterior chest wall. The internal thoracic artery travels along the inner surface of the anterior chest wall on both sides.
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.
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.
Where is the lateral thoracic vein?
The lateral thoracic vein (sometimes debatably referred to as the long thoracic vein) is a tributary of the axillary vein. It runs with the lateral thoracic artery and drains the Serratus anterior muscle and the Pectoralis major muscle.
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).
Is the internal thoracic artery an end artery?
The internal thoracic artery terminates at the level of the sixth rib or the sixth intercostal space, dividing into two terminal branches: the musculophrenic and superior epigastric arteries. The musculophrenic artery runs in an inferolateral direction, terminating before reaching the last intercostal space.
How many internal thoracic arteries are there?
Here are the two internal thoracic arteries. After passing behind the first rib, which is here, each one runs down the inside of the chest wall, just lateral to the sternum, in front of the transversus thoracis muscle. Its branches supply the anterior chest wall.
What artery is under your 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.
Which is true about axillary artery?
Correct answer : C. It extends from outer border of second rib to the lower border of teres minor. Axillary artery extends from outer border of first rib to the lower border of teres major. Pectoralis minor crosses the axillary artery and divides it into 3 parts.
