Swollen GlandsThe know-how of glands -
The glands with in the human body can be defined in two ways. Firstly they can be a cell, a group of cells, or an organ which produces a secretion for use in or for elimination from the body otherwise they can be any of various organs, like lymph nodes, which resemble true glands but perform non-secretory functions in the body. When we say swollen glands, we are basically referring to the glands defined second. Lymph nodes are glands which play an important part in the body's defense
against infection. They are small rounded or bean-shaped masses of lymphatic tissue surrounded by a capsule of connective tissue. They produce lymph, which travels throughout the body in the lymph system, and filtering impurities from the body. Common areas where the lymph nodes can be felt with hands include groin, armpit and neck where there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and also down each side of the back of the neck.
An Overview of Swollen Glands -
Commonly the term, gland swelling refers to enlargement of the lymph glands, also known as lymph nodes. Other glands that may be perceptible when swollen are the tonsils, parotid glands, salivary glands, tear (lacrimal) glands, and the thyroid gland.
Most swollen glands or lumps under the skin are not a cause for concern. The lymph nodes on either side of the neck, under the jaw, or behind the ears will swell even if a person has a cold or sore throat. However glands may swell and become tender and very firm due to more serious infections. An injury such as a cut or bite, or when a tumor or infection occurs in the mouth, head, or neck can also cause the glands to swell. Swelling of the lymph glands is typically a result of local or widespread inflammation, however sometimes enlarged lymph nodes are due to cancer. Swollen lymph glands are also referred as lymphadenopathy. Inflammation of the lymph node is known as lymphadenitis.
Common Causes:
Some infections that can cause swollen lymph nodes include mononucleosis, German measles (rubella), tuberculosis, mumps, ear infection, tonsillitis, an abscessed or impacted tooth, gingivitis (swelling of the gums), mouth sores, and even sexually transmitted diseases. Immune or autoimmune disorders which can cause swollen lymph nodes include rheumatoid arthritis and HIV. Cancers that can cause swollen glands include leukemia, Hodgkin's disease, or non-Hodgkin's lymphoma. Exactly which lymph node is swollen depends on the type of problem and the body parts involved.
