external definition
- Large median unpaired cartilage bone consisting of two diverging plates. Positioned medial to the eye. The orbitosphenoid develops from the Trabeculae communis and forms the anterior and anterolateral boundary of the orbital foramen and constitutes a significant part of the sidewalls and floor of the cranial cavity. Bordered by the lateral ethmoid anteriorly, and the pterosphenoid posteriorly, The orbitosphenoid may extend ventrally to meet the parasphenoid. In the adult, the orbitosphenoid is fused ventrally to the parasphenoid via a thin sheet of bone.[TAO]
- Endochondral ossification of the lateral sides of the braincase.[AAO]
