<br />
The '''Occipital Protuberance''' is a prominent feature of the [[human skull]], located at the posterior (back) part of the [[occipital bone]]. It is a significant point of attachment for several muscles and ligaments, playing a crucial role in head and neck movement.<br />
<br />
==Anatomy==<br />
<br />
The Occipital Protuberance is divided into two parts: the '''External Occipital Protuberance''' (EOP) and the '''Internal Occipital Protuberance''' (IOP). The EOP is a bony prominence on the outer surface of the occipital bone, while the IOP is located on the inner surface.<br />
<br />
===External Occipital Protuberance===<br />
<br />
The EOP is the point of attachment for the [[ligamentum nuchae]], a large ligament that extends down the back of the neck. It also serves as the attachment point for several muscles, including the [[trapezius muscle]] and the [[sternocleidomastoid muscle]], which are involved in head and neck movement.<br />
<br />
===Internal Occipital Protuberance===<br />
<br />
The IOP is located on the inner surface of the occipital bone, at the intersection of the grooves for the [[transverse sinuses]] and the [[superior sagittal sinus]]. It is a crucial landmark in neuroanatomy, as it marks the approximate location of the [[confluence of sinuses]], where several major [[dural venous sinuses]] converge.<br />
<br />
==Clinical Significance==<br />
<br />
The Occipital Protuberance can be palpated (felt) on the back of the head, and is often used as a landmark in medical examinations. It can also be used to guide the placement of [[cervical collars]] in trauma patients. In some cases, an enlarged or prominent Occipital Protuberance may be associated with certain medical conditions, such as [[Osteoarthritis]] or [[Diffuse Idiopathic Skeletal Hyperostosis]] (DISH).<br />
