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
