Which Structure Attaches to the External Occipital Protuberance?
The Inion Is the Most Prominent Projection of the Protuberance Which Is Located at the Posterioinferior (Lower Rear) Part of the Human Skull. the Nuchal...

Consequently, what attaches to the external occipital protuberance?
To it is attached, the splenius capitis muscle, the trapezius muscle and the occipitalis. From the external occipital protuberance a ridge or crest, the external occipital crest also called the median nuchal line, often faintly marked, descends to the foramen magnum, and affords attachment to the nuchal ligament.
Secondly, what muscle attaches to the occipital bone? Suboccipital muscles are located below the occipital bone. These are four paired muscles on the underside of the occipital bone; the two straight muscles (rectus) and the two oblique muscles (obliquus). Rectus capitis posterior major goes from the spinous process of the axis (C2) to the occipital bone.
In this regard, does everyone have an external occipital protuberance?
Yes, EVERYONE has an inion. But there is a difference between those with an ENHANCED inion or occipital protuberance and those who do not have this. IF your inion is enhanced, you can hook your fingers UNDER it. IF the inion is NOT enhanced there is NOTHING for the thumb to hook on to.
What is the purpose of the external occipital protuberance?
The external occipital protuberance is a raised area on the midline of the occipital bone where the posterior wall meets the base of the skull. The external occipital protuberance of the occipital bone is of functional importance because it is the origin for: 1. the trapezius muscle.
