Brachial lymph nodes
Brachial Lymph Nodes[edit]
The Brachial Lymph Nodes are a group of lymph nodes located in the upper arm region, specifically in the axilla or armpit. They play a crucial role in the immune system, acting as filters for harmful substances and are a part of the lymphatic system.
Anatomy[edit]
The brachial lymph nodes are typically divided into two groups: the lateral group and the central group. The lateral group is located along the medial side of the arm, while the central group is found near the second part of the axillary artery.
Function[edit]
The primary function of the brachial lymph nodes is to filter lymph, a clear or white fluid that carries white blood cells, especially lymphocytes, which are essential for the body's immune response. They also help in the detection and removal of foreign substances, including bacteria and cancer cells.
Clinical Significance[edit]
The brachial lymph nodes are often examined in medical diagnostics, particularly in cases of breast cancer and melanoma, as these cancers often spread to these nodes. The presence of cancer cells in these nodes can indicate that the cancer has spread beyond its original location.
