Which lymph nodes do the larynx drain into?

The larynx primarily drains into cervical lymph nodes. This is due to the anatomical relationship and the lymphatic drainage pathways associated with the structures of the neck. The lymphatics of the larynx follow the distribution of the branches of the superior laryngeal artery, which itself is a branch of the superior thyroid artery.

Lymph from the larynx typically drains into the deep cervical lymph nodes, particularly the nodes along the internal jugular vein. These nodes are significant as they play a key role in the immune response and also in the drainage of head and neck tissues. Additionally, involvement of these lymph nodes is important in the staging of head and neck cancers, including those affecting the larynx.

In this context, while it's relevant to know that there are other lymphatic structures in the body (like supraclavicular nodes or the thoracic duct), they do not primarily receive lymphatic drainage from the larynx as the cervical lymph nodes do. Therefore, the cervical lymph nodes are the correct answer for the anatomical understanding of laryngeal drainage.
