What is "occipital bone"?

The occipital bone is located at the back of the skull. It forms the lower and posterior parts of the cranium, serving as a protective structure for the delicate brain. The occipital bone has several prominent features, including the foramen magnum, which allows the passage of the spinal cord. It also contains the occipital condyles, which articulate with the first cervical vertebra (atlas), facilitating head movement and supporting the skull's connection to the spinal column. Additionally, the occipital bone provides attachment points for various muscles involved in neck and head movement. Its shape and position contribute to the overall stability and functionality of the skull and play a role in maintaining proper posture and balance.

Examples

1. The deformations were achieved by means of two splints, one at the frontal bone, and one at the occipital bone.

2. These surfaces articulate with two large cranial protuberances on either side of the foramen magnum on the occipital bone, to form the atlanto-occipital joint.

3. The deformations were achieved by means of two splints, one at the frontal bone, and one at the occipital bone.

4. This can include an overly prominent brow-ridge, s agittal crest or long occipital bone.
