The largest of these is the foramen magnum, ... The facial skeleton is one seventh of the size of the calvaria. (In the adult it is half the size).
The foramen magnum varies in size between individuals. Earlier ossification of the occipital bone leads to a smaller foramen. [5] The foramen magnum varies in size and shape when comparing different populations to each other. In humans, men tend to have a larger sized foramen magnum than women, but the overall shape is consistent. [6]
The squamous part is the curved, expanded plate behind the foramen magnum and is the largest part of the occipital bone. Due to its embryonic derivation from paraxial mesoderm (as opposed to neural crest, from which many other craniofacial bones are derived), it has been posited that "the occipital bone as a whole could be considered as a giant ...
