The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is ...

Occipital lesions can cause visual hallucinations. Lesions in the parietal-temporal-occipital association area are associated with color agnosia, movement agnosia, and agraphia.

Their afferent vessels drain the occipital region of the scalp , while their efferents pass to the superior deep cervical glands .
Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right.
