Noduli lymphatici laryngei, commonly referred to as laryngeal lymph nodes, are small bean-shaped structures found in the larynx, or the voice box. As part of the lymphatic system, their primary function is to help filter and trap foreign substances, such as bacteria, viruses, and other harmful agents, that may enter the larynx.
These lymph nodes are distributed within the mucous membrane lining of the larynx, particularly in the region of the posterior part of the glottis, known as the vocal cords, and around the vocal process of the arytenoid cartilage. They form a network of interconnected lymphatic vessels that facilitate the transportation of lymph fluid.
Noduli lymphatici laryngei play a pivotal role in the body's immune response system. When the larynx is exposed to pathogens or irritants, such as during a respiratory infection or vocal strain, the lymphocytes within these nodes become activated, initiating an immune response to eliminate the potential threat.
In certain medical conditions, such as laryngitis or laryngeal cancer, these lymph nodes can become inflamed or enlarged as a result of increased immune activity or the spread of malignancy. Healthcare professionals may assess the size, texture, and tenderness of these nodes during physical examinations to help diagnose and monitor such conditions.
Overall, noduli lymphatici laryngei are crucial components of the lymphatic system, aiding in the body's defense against infections and assisting in the maintenance of vocal health.
