Obliquus Capitis Inferior – A Misnamed Muscle

The emphasis of this article is on the importance of the naming of muscles, highlighted by the fact that the obliquus capitis inferior (OCI) is misnamed. However, the OCI is an important muscle in its own right. Given the prevalence of locked-short musculature in the posterior neck, especially in the supoccipital (upper neck) region, the OCI is extremely important clinically.

Rectus Capitis Posterior Major Suboccipital Muscle and Tension Headaches

The rectus capitis posterior major (RCPMaj) of the suboccipital group musculature is a small muscle located deep in the superior aspect of the posterior neck, directly inferior to the occiput (hence the name suboccipital). It is an extremely important muscle to know and be able to assess and treat because it is often responsible for clients’ tension headaches.
