Definition
-
The occipital protuberance, also known as the external occipital protuberance or inion, refers to a prominent bump or projection located at the back of the human skull. It is a slightly rounded or triangular region that serves as an attachment point for various muscles, ligaments, and tendons of the head and neck.
Found at the midline of the occipital bone, which is located at the base of the skull, the occipital protuberance is easily palpable on most individuals. It is typically situated at the top of the nuchal lines, which are horizontal ridges that extend laterally from the protuberance.
The occipital protuberance plays a significant role in providing structural support and stability to the head and neck region. It serves as an anchor point for important tissues and structures, including the nuchal ligament, trapezius muscle, and various muscles involved in head and neck movements.
Moreover, the occipital protuberance is clinically significant as it aids in the assessment of certain medical conditions and anthropological studies. It can provide valuable information regarding the individual's sex, age, and anatomical features. Additionally, it can be used as a reference point for accurate measurements and surgical procedures involving the cranial region.
In summary, the occipital protuberance refers to a visible bump at the back of the skull, serving as an attachment site for muscles and ligaments. It contributes to the structural stability of the head and neck and holds diagnostic relevance in the medical field.

Etymology of OCCIPITAL PROTUBERANCE
The word "occipital" originates from the Latin term "occiput", which refers to the back of the head or the posterior part of the skull. It is derived from the combination of two Latin words: "ob", meaning "against" or "towards", and "caput", meaning "head".
The term "protuberance" comes from the Latin word "protuberantia", which translates to "swelling" or "projection". It is derived from the verb "protuberare", meaning "to bulge out" or "to protrude".
Therefore, the etymology of the term "occipital protuberance" can be understood as a combination of "occipital" meaning the posterior part of the skull, and "protuberance" indicating a swelling or projection.
