"Fissure is the most common term in the anatomical and radiological literature for this petro-occipital articulation 1,2,5,8, but synchondrosis is sometimes used as well 3,4,8. Both terms appear in the Terminologia Anatomica. Synchondrosis implies a primary cartilaginous joint (here part of the chondrocranium) that usually ossifies during development. However, this structure very slowly ossifies well into late adulthood and is not entirely cartilaginous in adults, but rather a mix of dense connective tissue and cartilage 4. The term petro-occipital suture thus also appears in the literature, implying a fibrous union, but this usage is less common 1,6,7. "Fissure" may be preferable as a physical descriptor of a gap between bones, avoiding implications on the histological composition or developmental mechanism."
