Key Locations of Lymph Node Clusters: Neck, Armpit & Groin

Lymph nodes are densely clustered in the:

1. Neck: The cervical lymph nodes are located along the sides of the neck and are involved in filtering lymph from the head and neck region.

2. Axillary region (armpit): The axillary lymph nodes are located in the armpit and drain lymph from the upper extremities and breast.

3. Inguinal region (groin): The inguinal lymph nodes are found in the groin area and receive lymph from the lower extremities and pelvic organs.
