What does lateral thoracic supply?
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 artery 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.
What does a Thoracica interna supply?
The internal thoracic artery functions to supply the anterior chest wall, from the clavicle to the umbilicus. This area of supply also includes supply to the sternum and breasts.
Where is the axillary pulse?

Where does the lateral thoracic vein drain?
axilla
The lateral thoracic vein (TA: vena thoracica lateralis) is a tributary of the axillary vein. It provides venous drainage for the axilla, anterolateral chest wall, including serratus anterior and pectoralis muscles and breast, and the supraumbilical abdominal wall.
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. Axillary artery in the axilla. As soon as it exits the axilla, the axillary artery continues as the brachial artery.
Which arteries supply blood to the thoracic wall?
The thoracic wall is richly supplied with blood arising from three sources. These are the thoracic aorta, subclavian artery and axillary artery.
What are the visceral branches of the A Thoracica?
Anterior branches include the anterior intercostal, perforating and medial mammary arteries. Anterior intercostal branches diverge laterally from the internal thoracic artery to run into the first six intercostal spaces.
What does the Lima supply?
When the bilateral internal mammary artery (BIMA) is grafted in situ, the left internal mammary artery (LIMA) is generally used for the left descending artery (LAD) and the RIMA for the right coronary artery (RCA), or for the lateral wall, usually going through the transverse sinus.
What are the 3 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.
What is thoracic vein?
The internal thoracic veins (ITVs) are small paired vessels located on the ventral surface of the thoracic cavity that drain the ventro-cranial abdominal wall, the ventro-lateral thoracic wall, the diaphragm and part of the mediastinum, conveying blood from these regions into the cranial vena cava.
