Semispinalis Capitis connects the C4-T7 to the occipital bone trapping C1-C3. Dissection studies vary in their report of attachments on the thoracic vertebrae. They show that they not only vary in which vertebrae are attached but also that some slips attach to the transverse or spinous processes.
Origin – transverse processes of C7-T6 or T7 and the articular processes of C4-C6
Insertion – Between the superior and inferior nucal ridges of the occipital ridge
Function – Extension and some rotation of the head
