Delays in skeletal ossification were the result of the progressive prolongation of earlier phases of fetal growth, including crucial phases of neurogenesis.
He writes on institutional inertia, ceremonialism, and ossification.
His major example has to do with the centers of ossification in the skull of the human fetus.
Calcification should be differentiated f rom ossification, which usually has trabeculation.
Institutional ossification and institutional crisis are closely related.
Despite its very reduced size, the specimen appears to be an adult, based on the heavy ossification of most of the skeletal elements.
Defective vascular invasion o f cartilage promotes enlargement of the hypertrophic zones of the growth plate, which delays the formation of secondary ossification centers.
These bones are not preformed in cartilage but ossify from several ossification centres directly from ectomesenchyme, giving rise to the cranial vault (calvaria).
