What are the cervical lymph nodes?

Cervical lymph nodes are part of the lymphatic system that includes blood vessels, tissues and organs that help regulate the balance of body fluids and combat infections. The task of this system is to drain excess fluid, called lymph, from tissues and return to circulatory blood. There are about 300 lymph nodes in the neck, of which are about 300. They are classified in many different ways, mostly based on their location.

Lymph is clear and consists of proteins taken from the blood. This fluid flows from lymphatic capillaries. These are thin -walled blood vessels that are closed at one end and are located in the spaces between the cells throughout the body. Some of them, such as throat and tonsillitis, are relatively common. More serious diseases include lymphadenopathy, lymphoma and mononucleosis.

Lymphadenopathy is a term for swollen or enlarged Luzly ymph. This condition is more common in children than adults. There are many different reasons why a patient may have swollen nodes including infection,and may be difficult to diagnose the basic cause. In many cases, the nodes return to normal within two weeks; When swelling persists, the individual should see a doctor to diagnose.

One cause of swollen lymph nodes is mononucleosis. Mononucleosis, also known as "mono" or "kissing the disease", is caused by the Epstein-Barr virus. Saliva can be widespread, often replaced by drinking from drinking or tools to infected people, coughing, sneezing and kissing. They often spread people who show no symptoms. It is more common in preschool and young adults, but small children can get it by touching the toy with saliva.

Lymphoma is a type of cancer that affects the lymphatic system. One of the first symptoms is swollen armpits, weaknesses or cervical lymph nodes. Lymphom falls into two general categories: Hodgkin disease and non-hodgkin lymphoma.

Hodgkin is illA, from which there are several types, include a specific type of abnormal lymphocyte called reed-siens of the cell. The lymphoma of non-hodgkins also affects lymphocytes, but does not include Reed-Tenetberg cell development. There are many different types of non-hhodgkin lymphoma, depending on which lymphocytes are affected, the size of cancer cells, cellular growth formula and other factors.

Cervical lymph nodes are great indicators of the disease. Regular checks can help capture many diseases early. Early detection can often provide patients with the best possible result of the diseases or viruses that affect them.
