•Lymph nodes are masses of lymphatic tissue surrounded by a fibrous connective tissue capsule.
•The function of lymph node is to produce lymphocytes and to filter and trap substances from inflammatory and cancerous lesions.
•Special cells, called macrophages are located in lymph nodes which can phagocytose foreign substances.
•When bacteria are present in the lymph nodes, they become swollen with collections of cells and their engulfed debris and become tender.
lymph is a colourless watery substance similar to blood plasma. it contains cells called Lymphocytes. lymph transparts dead cells, bacteria and toxins to the lymph nodes where all the bacteria, dead cells and toxins are filtered from the lymph then the lymph returns to the blood stream once filtered =]
A lymph node (pronounced /ˈlɪmf noʊd/) is a small circular ball shape organ of the immune system, distributed widely throughout the body and linked by lymphatic vessels. Lymph nodes are garrisons of B, T, and other immune cells. Lymph nodes are found all through the body, and act as filters or traps for foreign particles. They contain white blood cells that use oxygen to process. Thus they are important in the proper functioning of the immune system.
Lymph nodes also have clinical significance. They become inflamed or enlarged in various conditions, which may range from trivial, such as a throat infection, to life-threatening such as cancers. In the latter, the condition of lymph nodes is so significant that it is used for cancer staging, which decides the treatment to be employed, and for determining the prognosis.
Lymph nodes can also be diagnosed by biopsy whenever they are inflamed. Certain diseases affect lymph nodes with characteristic consistency and location.(Source Wikipedia)
Lymph nodes (erroneously called lymph glands) are a part of the lymphatic system, a component of the body's immune system. Swollen lymph nodes may signal an infection.
There are several groups of lymph nodes, which are small, bean-shaped, soft nodules of tissue.
The ones most frequently enlarged or swollen are found in the neck, under the chin, in the armpits, and in the groin.
Lymph nodes are responsible for keeping your immune system healthy. This means they must filter out harmful substances that could make a person sick.

What is a fatty hilum?
A fatty hilum is a region of connective tissue within a lymph node that contains an accumulation of fat. It is a normal part of lymph node anatomy and serves to provide support and structure to the lymph node.
What is reactive lymph node?
It's a lymph node that drains an inflamed area. The source of the inflammation can be bacterial-viral infection, immunological disease, or malignancy.
What distinguishes a sentinel node from other nodes?
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
What is most important in stage determination and regional lymph node involvement?
Of primary importance to stage determination and regional lymph node involvement is identification and analysis of the sentinel lymph node.
What is the word root for lymph node?

What is a superficial lymph node?
