External Occipital Protuberance (EOP) is an anatomical structure located on the occipital bone's posterior surface, at the superior nuchal line level. It is the insertion site of the nuchal ligament and the trapezius muscle [6, 16].
What Is the External Occipital Protuberance? (with pictures)
There is a small ridge of bone which arises from the squamous part of the occipital bone known as the external occipital crest. It acts as a site of attachment for the nuchal ligament. The parietal bones are difficult to visualise from the inferior view of the skull, however they can be seen articulating with the temporal and occipital bones.

External occipital protuberance (EOP) is a midline bony prominence in the occipital bone that ligamentum nuchae and trapezius muscle attach to its tip that named Inion. The tentorium cerebelli attaches to its internal surface. Entheses are the sites of ligament, tendon or joint capsule attachment to the bone..

At its midline is a prominence called the external occipital protuberance, with its highest point termed the inion. The superior nuchal line makes an intersection with a vertical midline ridge of bone called the medial nuchal line, which is also known as the external occipital crest, forming an uppercase "T" on the surface of the occipital.

Case Discussion. External occipital protuberance is a midline bony prominence in the occipital bone that ligamentum nuchae and trapezius muscle attach to its tip. The tentorium cerebelli attaches to its internal surface. Exaggerated external occipital protuberance also is known as an occipital spur.

Occipital spurs, also called as occipital knob, occipital bun, chignon or inion hook, is an exaggerated external occipital protuberance (EOP). It is frequently discussed in anthropological literature as a Neanderthal trait but hardly reported and considered as a normal variant in medical literature. It is a frequent finding among males and hence a prominent occipital spur is often used in.
Prominent External Occipital Protuberance Radiology
Near the middle of the squamous part of occipital bone is the external occipital protuberance, the highest point of which is referred to as the inion. The inion is the most prominent projection of the protuberance which is located at the posterioinferior (rear lower) part of the human skull. The nuchal ligament and trapezius muscle attach to it.

External occipital protuberance Protuberantia occipitalis externa. Definition. The under surface of the jugular process is rough, and gives attachment to the Rectus capitis lateralis muscle and the lateral atlantoöccipital ligament; from this surface an eminence, the paramastoid process,sometimes projects downward, and may be of sufficient.

The occipital squama is the larger, more posterior portion of the external occipital bone. It is a thin, flat bone that forms the base of the skull and contributes to the formation of the posterior cranial fossa.The occipital squama is marked by several prominent features, including the external occipital protuberance, the external occipital crest, and the superior nuchal lines.

The squamous part is the largest of all four and contains both internal and external surfaces. A palpable prominence known as the external occipital protuberance lies on the midline of the external surface which serves as an attachment for the trapezius muscle.. Furthermore the external surface features three curved lines referred to as nuchal lines:

Occipital Bone. The occipital bone is the single bone that forms the posterior skull and posterior cranial fossa (Figure 7.3.8; see also Figure 7.3.7). On its outside surface, at the posterior midline, is a small protrusion called the external occipital protuberance, which serves
