Skull Bone Protecting the Brain The occipital bone is the trapezoid-shaped bone a the lower-back of the cranium (skull). The occipital bone houses the back part of the brain and is one of seven bones that come together to form the skull. It located next to five of the cranium bones..
Consequently, what does the occipital bone articulate with?
7.21The occipital bone is set at the rear of the cranium and articulates with the temporals, sphenoid, parietals, and the uppermost vertebra, the atlas.
One may also ask, what are characteristics of the occipital bone? It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum. At the base of skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord.
Consequently, what is the main function of occipital bone?
Structure and Function. The occipital bone is a very complex bone that serves primarily to protect the cerebellum and the occipital lobes of the cerebrum and to provide attachment to several muscles and ligaments described below. It is trapezoidal and shallowly curved on itself.
Can the occipital bone move?
Irregular suture. The occiput and the mastoid part of the temporal bone normally move in opposing directions to each other: in the inspiration phase the border of the occiput moves in an anterior direction, while the border of the mastoid part slides posterior.

The occipital lobe is no exception. Although its primary role is to control vision, damage to other brain regions and body parts can inhibit vision.
