The bones of the cranial vault are composed of two plates of
compact tissue separated by an inner layer of spongy tissue called
Diploe
The articulations or joints of the cranium
Sutures
separates the frontal bone from the two
parietal bones
Coronal sutures
separating the two parietal bones in
the midline
Sagittal suture
separates the two parietal bones from
the occipital bone
Lambdoidal Suture
are formed by the inferior junctions of
the two parietal bones with their respective temporal
bones
Squamosal Sutures
The anterior end of the sagittal suture.
Bregma
The posterior end of the sagittal suture
Lambda
are points posteriorto the ear where the
squamosal and lambdoidalsutures meet.
Asterions
are points at the junction of the parietals,
temporals, and the greater wings of the sphenoid.
Pterions
