Anterior cervical lymph nodes
(Redirected from Nodi lymphoidei cervicales anteriores)
Anterior cervical lymph nodes are a group of lymph nodes located in the anterior (front) part of the neck. These lymph nodes play a crucial role in the lymphatic system, which is part of the body's immune system. They are responsible for filtering lymphatic fluid and trapping pathogens, such as bacteria and viruses, to prevent infections and diseases.
Anatomy[edit | edit source]
The anterior cervical lymph nodes are situated along the anterior jugular vein and are divided into several subgroups based on their location and the structures they drain. These subgroups include:
- Prelaryngeal lymph nodes: Located in front of the larynx.
- Pretracheal lymph nodes: Situated in front of the trachea.
- Paratracheal lymph nodes: Found alongside the trachea.
Function[edit | edit source]
The primary function of the anterior cervical lymph nodes is to filter lymphatic fluid from the head and neck region. They trap and destroy harmful microorganisms and foreign particles, which helps in preventing the spread of infections. These lymph nodes also play a role in the activation of the immune response by presenting antigens to lymphocytes.
Clinical Significance[edit | edit source]
Enlargement of the anterior cervical lymph nodes, known as lymphadenopathy, can be a sign of various medical conditions, including infections, inflammatory diseases, and cancers. Common causes of lymphadenopathy in this region include:
- Upper respiratory tract infections
- Tonsillitis
- Pharyngitis
- Thyroid disorders
- Lymphoma
- Metastatic cancer
Diagnosis and Treatment[edit | edit source]
Diagnosis of anterior cervical lymphadenopathy typically involves a thorough medical history and physical examination. Additional diagnostic tests may include:
Treatment depends on the underlying cause of the lymphadenopathy. Infections may be treated with antibiotics or antiviral medications, while cancers may require chemotherapy, radiation therapy, or surgery.
