Lymph Nodes Prececal

Prececal lymph nodes: anatomy and function

The lymphatic system plays an important role in protecting the body from infections and diseases. It consists of various components, including lymph nodes, which perform the function of filtering and purifying lymph. One of the important components of the lymphatic system are the prececal lymph nodes (n. l. prececales, PNA).

The anatomical location of the prececal lymph nodes can vary, but they are usually located near the rectum and are part of the lymphatic system of the colon. These nodes may be palpable during a medical examination.

The function of the prececal lymph nodes is to filter lymph coming from the rectal area. Lymph contains many cells, including lymphocytes, which are key players in the immune system. The prececal lymph nodes serve as a site for activation and proliferation of lymphocytes, and also filter the flow of lymph, trapping and removing pathogens, microorganisms and other harmful substances.

If there is inflammation or infection in the rectal area, the prececal lymph nodes may increase in size, become painful, and may be palpable during examination. This indicates the activation of the immune system and its fight against infection.

Some diseases or conditions may be associated with changes in the prececal lymph nodes. For example, rectal tumors can spread to the lymph nodes, which is an important factor in cancer staging and optimal treatment. Also, inflammatory diseases, such as chronic proctitis or ulcerative colitis, can cause inflammation of the prececal lymph nodes.

Various methods can be used to diagnose and evaluate the condition of pre-colic lymph nodes, including palpation, ultrasound, computed tomography and biopsy. These methods allow doctors to obtain information about the size, shape and structure of nodes, as well as to identify the presence of pathological changes.

In conclusion, the prececal lymph nodes play an important role in the functioning of the body's lymphatic system. They perform the function of filtration, activation of immune cells and purification of lymph from harmful substances. Changes in the prececal lymph nodes can be associated with various diseases, so their diagnosis and assessment of the condition are important for determining further treatment tactics. Understanding the anatomy and function of the prececal lymph nodes helps physicians detect and evaluate pathological changes associated with this area and provide effective treatment.



The lymphatic system is one of the most important components of our body, which plays a key role in maintaining immunity and fighting infections. Speaking about the lymph nodes of the prececal space, we can determine that they are accumulations of lymphatic vessels and tissues located in the abdominal cavity, before entering the intestine. These nodes are part of the lymphatic system, which forms a major part of the body's immune defense against various infections and toxins.

The lymph nodes of the precolon space are located in the area of ​​the abdominal cavity between the small and large intestines and are sometimes called "lower abdominal lymph nodes." They are located close to the abdomen, but relatively deep. The size of these nodes can vary from a few millimeters to 2-3 centimeters in diameter. They may be sensitive when palpated with the hands, although they usually remain invisible to superficial finger movements. However, if there is an increase in size or other changes that may include obvious tightness or discomfort in the abdominal area, you should consult a doctor.

The lymph nodes of the precolic space are also characterized by a gradual increase in size during pregnancy. They are located approximately 3-10 cm above the pubic bone and expand approximately 2 times more during pregnancy. This expansion is associated with increased fluid supply to the tissues by improving blood supply and can occur during the postpartum period. Typically, these nodes will return to their original size within a few months of stopping breastfeeding.
