The occipital bone is located on the back of the skull. The occipital protuberance can be seen/felt on the back of the head, as it is the rather large bump. This occipital bone encloses a large oval hole called the foramen magnum which allows the spinal cord to pass through.

The occipital lymph node is part of the lymphatic system that is located on the back of the head. It produces white blood cells and lymph.

The large hole in the occipital bone is called the foramen magnum and is the place where your spinal column comes up to meet your brain.
