OCCIPITOAXIAL Meaning and
Definition
-
Occipitoaxial is an anatomical term that refers to the region or structure formed by the occipital bone and the axis vertebrae. The occipital bone is a flat, curved bone that forms the back and base of the skull, while the axis (or second cervical vertebra) is the bone of the spine that allows for rotational movement of the head.
Occipitoaxial commonly describes the joint between the occipital bone and the axis vertebrae, also known as the atlanto-axial joint. This joint allows for a significant amount of movement in the head, including nodding and rotation. It plays a crucial role in providing stability and support to the head, as well as in enabling efficient movement and coordination.
In medical contexts, occipitoaxial may also refer to conditions or pathologies associated with this joint. For example, occipitoaxial instability or occipitoaxial subluxation refers to the abnormal movement or misalignment of the occipital bone and the axis vertebrae. These conditions can cause compression of the spinal cord or nerve roots, resulting in neurological symptoms such as neck pain, limited mobility, tingling, or weakness in the arms or legs.
Overall, occipitoaxial is a term used to describe the region and joint formed by the occipital bone and the axis vertebrae, as well as any associated conditions or pathologies related to this anatomical area.

Etymology of OCCIPITOAXIAL
The word "occipitoaxial" is derived from two roots: "occipital" and "axial".
"Occipital" comes from the Latin word "occiput", meaning "the back of the head", specifically the bone that forms the back and base of the skull. The Latin term is a combination of "ob" (meaning "in front of" or "against") and "caput" (meaning "head").
"Axial" comes from the Latin word "axis", meaning "axis" or "pivot". In anatomy, "axial" refers to the main central axis of the body, comprising the head, neck, and trunk.
When combined, "occipitoaxial" refers to the region between the occiput (back of the head) and the axial (central) portion of the body.
