Inion

Inion is a term used in anatomy to refer to the most prominent projection of the occipital bone at the base of the skull. The inion is used as a landmark in various medical procedures and is also significant in forensic science for the identification of human remains.

Anatomy

The inion is located at the lower part of the back of the head, also known as the occipital region. It is the most prominent part of the occipital bone, which forms the base of the skull. The inion is the external occipital protuberance of the skull, and it is located in the midline, just above the nape of the neck.

Clinical significance

The inion is used as a landmark in various medical procedures. For example, it is used in the Rancho Los Amigos Scale to measure the level of consciousness in patients with brain injury. It is also used in the placement of electroencephalography (EEG) electrodes to measure brain activity.

In forensic science, the inion is significant for the identification of human remains. The shape and size of the inion can provide clues about the age, sex, and race of the individual.
