Central Nervous System Tumors (Brain and Spinal Cord) - Childhood: Medical Illustrations

Approved by the Cancer.Net Editorial Board, 06/2022

ON THIS PAGE: You will find a drawing of the main body parts affected by a childhood central nervous system (CNS) tumor. Use the menu to see other pages.

This illustration shows several views of a child’s brain and central nervous system. A medial (side) view of the brain shows the cerebrum and cerebellum. The cerebrum is largest part of the brain and made up of four lobes: the frontal lobe at the front of the skull, the parietal lobe at the upper rear of the skull, above the occipital lobe, and the temporal lobe, which is located under the frontal and parietal lobes on both sides of the cerebrum. The cerebellum is located under the occipital and temporal lobes at the rear of the skull. The cross section of the brain shows the long corpus callosum located under the cerebrum in the center of the brain, the septum pellucidum, which runs down from the corpus callosum, and the diencephalon, which connects the cerebrum and the brain stem. The brain stem is the lowest part of the brain, and made up of 3 parts: the midbrain, the pons, which bulges out from the medulla oblongata, which in turn connects to the spinal cord. The fourth ventricle is a fluid filled space between the brain stem and the cerebellum, underneath the colliculi of the midbrain. An overall view of the body show that the spinal cord extends from the brain stem down the back. Peripheral nerves branch out from the spinal cord to the rest of the body.
