The lymphatic fluid from the head and neck regions is filtered by the lymph nodes in the neck area. As the trabeculae penetrate the lymph node they continue as reticulin fibrils type III collagen that offer additional structural support to the gland. Pretracheal nodes are positioned in front of the trachea or windpipe at the bottom center of the neck.

Peripheral lymph nodes aka. 3APre-vascular These nodes are not adjacent to the trachea like the nodes in station 2 but they are anterior to the vessels. Outlying lymph nodes are located in groups and are organized in outer and inner circles.

Lymph nodes are situated at strategic positions throughout the body and serve to filter the lymph. Lymph nodes are bean-shaped structures about 01 25 cm in length. Lymph node any of the small bean-shaped masses of lymphoid tissue enclosed by a capsule of connective tissue that occur in association with the lymphatic vessels.

The convexed surface of the lymph node is pierced by numerous afferent lymph vessels. Lymph nodes are kidney shaped structures which act to filter foreign particles from the blood and play an important role in the immune response to infection. Anatomy of lymph node.

They filter lymph fluid before returning it to the bloodstream. They bring the lymph the tissue fluid surrounding the cells which contains white blood cells lymphocytes fluid from the intestines chyle. Abdominal Lymph Node Anatomy Lymphatic Spread of MalignanciesLiver Hepatocellular carcinoma HCC is the most common primary visceral malignancy 12.

They extend to the deeper areas of the lymph node by way of the trabecular extensions of the cortex. 3PPre-vertebral Nodes not adjacent to the trachea like the nodes in station 2 but behind the esophagus which is prevertebral. The exception is the central nervous system CNS where there are no lymph nodes.

Located in the femoral triangle of the inguinal region they are grouped into superficial and deep lymph nodes. Lymph nodes can be found in every area of the body. Generallyoval bean shaped structures scattered throughout body along lymphvesselsUsually 1-25 mm in lengthmay be deep or superficialconcentrated along the respiratory tree and GI tract in the mammaryglands axillae and groinfilter lymph fluid to trap foreign organisms cell debris and tumor cells.

Lymph node levels of the head and neck annotated CT Case contributed by Dr Maciej Debowski. As part of the lymphatic system lymph nodes serve as filters for the blood providing specialized tissues where foreign antigens can be trapped and exposed to cells of the immune system for destruction. They are major sites of lymphocytes that include B and T cells.

The lymph nodes in the region of the head and neck are broadly classified into two groups. The node is enclosed in a capsule and has an indentation on one surface along one of its long axes known as the hilum.

The hilum of the lymph nodes is the primary point of entry for. The hilum is the point at which arteries carrying nutrients and lymphocytes enter the lymph node and veins leave it. Lymph nodes are specialized tissue masses that are located along lymphatic system pathways.

On average an adult has around 400 to 450 different lymph nodes spread throughout the body with the majority located within the abdomen. A lymph node or lymph gland is a kidney -shaped organ of the lymphatic system and the adaptive immune system. Lymph node metastases LNM are rare and generally associated with poor prognosis in hepatocellular carcinoma see Fig.
