Top View of the Skull & #8211; Skullcap
The upper part of the skull is called the skull dome or calvaria.
It is crossed by Four Sutures (joints that allow minimal mobility to skull bones):
1 – Coronal or Bregmatic Suture: between the frontal and parietal bones
2 – Sagittal Suture: between the two parietals (median sagittal line)
3 – Suture Lambdoid: between the parietals and the occipital
4 – Scaly Suture: between the parietal and the temporal
Some Anthropometric Points of the Skull:
Bregma & #8211; joint point of sagittal and coronal sutures
Lambda & #8211; junction point of the sagittal and lambdoid sutures
Vertex & #8211; highest part of the skull
Gonius & #8211; jaw angle
Pterius & #8211; junction point of the parietal, frontal, sphenoid and temporal bones
