The five regions of lymph nodes in the neck are the anterior cervical, posterior cervical, submandibular, submental, and supraclavicular regions. The anterior cervical region includes the superficial and deep anterior cervical nodes, while the posterior cervical region comprises the superficial and deep posterior cervical nodes. The submandibular region contains the submandibular lymph nodes, the submental region includes the submental lymph nodes, and the supraclavicular region features the supraclavicular lymph nodes. These lymph nodes play crucial roles in draining lymph from various structures in the head and neck.
The tributary region of the axillary lymph nodes primarily includes the upper limb, breast, and the thoracic wall. Lymphatic drainage from these areas flows into the axillary lymph nodes, which play a crucial role in filtering lymph and facilitating immune response. Additionally, they receive lymph from parts of the back and the upper part of the abdomen. This network is essential for monitoring and responding to infections or malignancies in these regions.
