This illustration shows the primary distribution of neuroblastoma in children, highlighting the neck, chest, abdomen, and pelvis. A detail shows the spine, stretching from the cervical vertebra at the top to the lumbar vertebra at the bottom. The kidneys are located on either side of the spine just above the waist, and the adrenal glands are located on top of both kidneys. Clusters of nerve cells, called sympathetic ganglion, run up and down the length of the spine on the sympathetic trunks, located along either side of the vertebrae.
