Sometimes these lymph nodes are detected by mammography on the lateral part, which is located at the top of the quadrant of the breast. Axillary lymph nodes in the mammary gland Moreover, they are designated even by a special symbol M. They are on the side of the lesion, that is, they most often suffer from breast cancer. Regional lymph nodes are also referred to as internal ones. These include subclavian and apical lymph nodes. They are located in the center, relative to the medial edge of the small pectoral muscle. The third level is represented by the apical axillary nodes. They are located in the area between the medial and lateral margins of the small pectoralis muscle. The second level is the middle axillary nodes.

They are located laterally to the lateral border with a small pectoralis muscle. The first level is the lower axillary nodes. To the regional lymph nodes, located in the mammary gland, include a whole group of axillary nodes.

Its 'composition' includes a mass of lymph nodes of various stages. The mammary gland is characterized by its complex structure. They are located in the area between the small and large pectoralis muscle. In the mammary gland there are also unstable lymph nodes. Then through the ribs they penetrate to the parasternal lymph nodes, that is, the first stage. Some of the vessels pass not only through the large, but also the small pectoral muscles. From this site, lymph begins to flow into the central axillary lymph nodes. After that they permeate the large pectoralis muscle and pass into interintegral nodes. The glands of lymphatic vessels from their base follow to the lymph nodes of the retroammammary space. The nodes of the second stage include vascular vessels of the axillary lymph nodes. They are referred to the number of nodes of the first stage of the outflow from the mammary gland. Parasternal lymph nodes are located on the second to fourth intercostal space. The largest cluster of them is observed within the second to fourth intervals. They are in the first to the seventh intercostal spaces. Parasternal lymph nodes are located along the internal mammary artery. Simultaneously, they relate to the nodes of the first stage of the upper section of the breast. They are referred to the nodes of the first stage, which are included in the upper quadrants of the mammary glands. They are located in the area under the collarbone. The posterior axillary nodes have a slightly different arrangement and extend along the subscapular artery.Īnother group of lymph nodes includes lymph nodes located under the clavicle. To them there is an outflow of lymph from the outer quadrants of the mammary gland. The central nodes are located along the axillary vein. External or lateral axillary nodes are located near the lateral thoracic artery. This includes external, central and subscapular nodes. Some of them are on the surface, they are divided into three subgroups. The main and largest group of lymph nodes are axillary groups. Localized on the fourth tooth, sometimes called the Bartels node. They, in turn, are the lymph nodes of the first stage. The vasoconstrictors, which form the basis of the structure of the lymph nodes of the mammary glands, flow into the axillary lymph nodes. They are the main nodes of the first stage. Paramammary lymph nodes are located on the large pectoral muscle, along its outer edge. Structure of lymph nodes of mammary glands
