What is the name of the bone that forms the back of the skull above the nape?

The bone that forms the back of the skull above the nape is known as the occipital bone. This bone plays a crucial role in enclosing the brain and providing structural support to the skull. The occipital bone is characterized by its large foramen magnum, an opening that allows the spinal cord to connect to the brain. Its location and shape are particularly important as they allow for the attachment of muscles and ligaments that support head movement and maintain posture.

In contrast, the frontal bone is located at the front of the skull and forms the forehead, while the temporal bones are situated on the sides and base of the skull, and the parietal bones are found on the sides of the skull, above the occipital bone. Each of these bones has distinct functions and locations that differentiate them from the occipital bone.
