OPISTHION Meaning and Definition

1. Opisthion is a term used in anatomy and biology to refer to a specific landmark or structure located at the back of the head or skull. More precisely, it is a point or bony prominence on the inner surface of the occipital bone of the skull. It is situated slightly above the foramen magnum, which is a large opening in the lower part of the skull that allows the spinal cord to connect with the brain.

   The opisthion is an important anatomical landmark used in various scientific disciplines. For instance, in clinical and radiological studies, the opisthion is often used as a reference point in determining the position or alignment of the structures within the head and neck region. It can be particularly relevant when assessing the alignment of the spine and skull in relation to conditions such as spinal deformities or skeletal anomalies.

   Moreover, the opisthion is also of significance in paleoanthropology and evolutionary biology. Scientists use it as a reference point to study the cranial morphology and structure of different species and to determine important evolutionary changes that may have occurred throughout time.

   In summary, opisthion is a term that primarily refers to a bony prominence located at the back of the skull, slightly above the foramen magnum. It serves as a crucial anatomical landmark in clinical, radiological, and evolutionary studies, assisting in various assessments and investigations of the head and neck regions.

2. The middle point on the posterior margin of the foramen magnum, opposite the basion.

In anatomy, the opisthion refers to a specific anatomical landmark located at the posterior base of the skull. It is the midpoint between the tip of the dens (a bony projection of the second cervical vertebra) and the highest point of the occipital bone, which forms the back part of the skull.
