The colon has numerous lymph nodes associated with it, typically numbering in the hundreds. These lymph nodes are part of the lymphatic system and are distributed along the blood vessels that supply the colon. They play a crucial role in immune function and the drainage of lymphatic fluid from the colon. The exact number can vary among individuals and depends on the specific segments of the colon being considered.

Surgical removal of the involved segment of colon (colectomy) along with its blood supply and regional lymph nodes is the primary therapy for colon cancer.

Yes, colitis can cause swollen lymph nodes in the colon. Inflammatory conditions like colitis lead to immune system activation, which may result in lymphadenopathy as the body responds to inflammation or infection. This is particularly common in conditions such as ulcerative colitis and Crohn's disease. If swollen lymph nodes are present, it's essential to consult a healthcare professional for evaluation and appropriate management.
Perivascular lymph nodes are found near the aorta. They are involved in many diseases of the human body and they represent visceral nodes.

Lymph Nodes
Anterior and posterior cervical lymph nodes.
The pectoral lymph nodes are also known as the anterior group and can be found just inferior to the pectoralis minor muscle, the cephalic nodes are also known as deltopectoral lymph nodes and they receive lymph from the superficial vessels only
No, axillary lymph nodes are not the same as infraclavicular and supraclavicular lymph nodes. Axillary lymph nodes are located in the armpit region and are primarily involved in draining lymph from the upper limb and breast. Infraclaviular lymph nodes are situated below the clavicle, while supraclavicular lymph nodes are located above the clavicle, each serving different drainage areas. Despite their proximity, they are distinct groups of lymph nodes with specific functions.
There are many chains or groups of lymph nodes in the posterior pelvic area, draining centrally to the aortic groups of lymph nodes.
