posterior skull base

The posterior skull base is the part of the inside of your skull that forms the bottom and back surface of the brain’s protective basin. It includes bones like the occipital bone, which surrounds the lower part of the brain and connects to the spinal cord, and parts of the temporal bones. This area helps support and protect vital structures like the brainstem, cerebellum, and blood vessels passing between the brain and spinal cord. Its well-structured anatomy is crucial for brain protection, nerve passage, and overall skull stability.
