Anatomical locations on the body that contain lymph nodes are the head and neck, the upper and lower torso, the arms, and the legs, according to InnerBody. The lymph nodes in the head and neck include the adenoids, lingual and palatine tonsils, and cervical nodes.
The cervical nodes are in the lower jaw, around the ears and near the blood vessels in the neck, explains InnerBody. They serve the face, the pharynx, the scalp and the nasal passages and help produce white blood cells.
The lymph nodes in the upper body include those in the jugular trunk, the intercostal and branchopulmonary nodes, notes InnerBody. The jugular trunk serves parts of the head and the neck, while the intercostal nodes drain the back of the chest cavity. The branchopulmonary nodes are in an area inside the lung. The sizes of these nodes vary.
Peyer's patches are lymph nodes found in the small intestine, reports InnerBody. They regulate the populations of bacteria found in the area and combat pathogens. Technically, they are lymphatic nodules because capsules of connective tissue do not surround them.
The lumbar trunk drains the legs, the pelvis and the lower abdomen. The cubital nodes are near the elbow and serve the arm and the hand, while popliteal nodes are near the knees and drain the lower legs and the feet, according to InnerBody.
