Squama occipitalis

Squama occipitalis is a part of the human skull that forms the posterior part of the cranium. It is a flat, curved bone that is located at the back of the head, above the foramen magnum. The squama occipitalis is part of the occipital bone, which is one of the eight cranial bones.

Anatomy

The squama occipitalis is a curved, rectangular bone that forms the back and base of the cranium. It is bordered by the parietal bones on either side and the sphenoid bone at the front. The squama occipitalis is marked by several important anatomical features, including the external occipital protuberance, the superior nuchal lines, and the inferior nuchal lines.

Function

The primary function of the squama occipitalis is to protect the brain and support the back of the head. It also provides attachment points for several muscles, including the trapezius, sternocleidomastoid, and splenius capitis muscles.

Clinical significance

Injuries or diseases affecting the squama occipitalis can lead to serious health problems, including head trauma, skull fractures, and brain damage. In addition, abnormalities in the shape or size of the squama occipitalis can be indicative of certain genetic disorders, such as craniosynostosis.
