Where are lymph nodes mainly located?

They are typically found concentrated near junctions of the major lymphatic vessels, most prominently in the neck, groin, and armpits. Each lymph node is divided into two general regions, the capsule and the cortex. The capsule is an outer layer of connective tissue.

What is called lymph?

Lymph (from Latin, lympha meaning “water”) is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.

How is lymphoma caused?

Doctors aren’t sure what causes lymphoma. But it begins when a disease-fighting white blood cell called a lymphocyte develops a genetic mutation. The mutation tells the cell to multiply rapidly, causing many diseased lymphocytes that continue multiplying.

Where are the locations of lymph nodes in my body?

Of the hundreds of lymph nodes located throughout the body, as stated before, not all of them are near the surface and will notice when swollen. Keep in mind, the common cold and flu will cause ones along the neck to swell during the battle against the viral or bacterial infection.

Where does lymph drainage from the abdomen go?

Lymph from the abdomen and thoracic cavity drain through these nodes. The Virchow’s node is a left supraclavicular node which picks up the lymph drainage from for the most parts of the body particularly the stomach passing through the thoracic duct and is thus a premature location of metastasis for a number of malignancies.

Where does the lymph go after leaving the capsule?

Gross Anatomy. Afferent lymphatic vessels enter the lymph node through the capsule peripherally and efferent lymphatic vessels leave the node via the hilum. The former takes lymph from peripheral sites to the node, while the latter takes processed lymph from the nodes back to the venous circulation.

Where are the submental lymph nodes located on the tongue?

Submental lymph nodes are situated just beneath the chin. Lymphs from the central incisors and the lower lip midline and the tip of the tongue drain from these nodes.
