extends all the way around
the vault of the fetal skull is made up of how many bones?
seven
the seven bones that make up the vault of the fetal skull:
2 x frontal bones
2 x parietal bones
occipital bone
2 x temporal bones
what are sutures in the fetal skull?
cranial joints formed when two bones meet
when two or more sutures meet, a ? is formed
fontanelle

frontal
the sagittal suture lies between:
the two parietal bones
the ? suture separates the parietal bones from the frontal bones
the coronal suture
the ? suture separates the occipital bone from the two parietal bones:
lambdoidal
what is moulding?
when sutures and fontanelles found in the fetal skull allow a degree of overlapping during childbirth
the lambdoidal fontanelle runs between:
back of skull
the occipital bone and the two parietal bones
the bregma fontanelle runs between:
top of skull
two frontal bones and two parietal bones
