Central group: Lying in the center of the axilla in the axillary fat, these nodes receive lymph from the above three groups. Infraclavicular (deltopectoral) group: These nodes are not strictly axillary nodes because they are located outside the axilla. They lie in the groove between the deltoid and pectoralis major muscles and receive ...
A central or intermediate group of three or four large glands is imbedded in the adipose tissue near the base of the axilla. Its afferent lymphatic vessels are the efferent vessels of all the preceding groups of axillary glands ; its efferents pass to the subclavicular group .
Deltoideopectoral nodes: Situated between the pectoralis major and deltoid muscles inferior to the clavicle. Deep lymph nodes of the arm: These comprise the axillary nodes, which are 20-30 individual nodes and can be subdivided into: Lateral nodes; Anterior or pectoral nodes; Posterior or subscapular nodes; Central or intermediate nodes
A lymph node, or lymph gland, [1] is ... the axillary lymph nodes under ... the efferent lymphatic vessel towards either a more central lymph node or ultimately for ...
An anterior or pectoral group consists of four or five glands along the lower border of the Pectoralis minor, in relation with the lateral thoracic artery.. Their afferents drain the skin and muscles of the anterior and lateral thoracic walls, and the central and lateral parts of the mamma; their efferents pass partly to the central and partly to the subclavicular groups of axillary glands.
Lymphadenopathy of the axillary lymph nodes can be defined as solid nodes measuring more than 15 mm without fatty hilum. [36] Axillary lymph nodes may be normal up to 30 mm if consisting largely of fat. [36] In children, a short axis of 8 mm can be used. [37]

The parasternal lymph nodes (or sternal glands) are placed at the anterior ends of the intercostal spaces, by the side of the internal thoracic artery.. They derive afferents from the mamma; from the deeper structures of the anterior abdominal wall above the level of the umbilicus; from the upper surface of the liver through a small group of glands which lie behind the xiphoid process; and ...
