The term "sulcus occipitalis superior" refers to a groove found in the superior part of the occipital bone. The spelling of this anatomical term can be explained using the International Phonetic Alphabet (IPA). The 's' in "sulcus" is pronounced as /s/ while the 'u' is pronounced with a short /ʌ/ sound. The 'l' is pronounced as /l/. The stress falls on the third syllable, with the 'o' pronounced as /ə/. In "occipitalis", the 'c' is pronounced as /k/ and the 't' as /t/. Finally, the 's' in "superior" is pronounced as /s/.
The term "sulcus occipitalis superior" refers to a specific anatomical feature located on the superior (upper) surface of the occipital bone in the human skull. The occipital bone is positioned at the back and base of the skull, forming the posterior part of the cranial cavity. This bone consists of multiple prominences, ridges, and grooves that are essential for attaching muscles, accommodating blood vessels, and protecting the brain.
The sulcus occipitalis superior, also known as the superior occipital sulcus, is a shallow groove or furrow found on the upper aspect of the occipital bone. It extends horizontally in a posterior direction from the midline of the skull towards the sides, roughly parallel to the sagittal suture. The sulcus occipitalis superior does not possess any distinct function on its own, but it serves as a reference point for various anatomical landmarks and structures.
This superior occipital sulcus plays a role in the attachment and stabilization of tissues and structures that surround it, such as the outer layer of the brain called the dura mater and the various muscles involved in head movements. Its precise location and distinctive shape aid medical professionals in accurately identifying and referencing different areas of the skull during clinical assessments, surgical procedures, and radiographic interpretations.
Superior occipital s., one of several small and variable sulci separating the superior occipital gyri on the upper aspect of the occipital lobe of the cerebrum.
