The four major sutures

Squamous suture

on each side of the skull joins the temporal bone and the parietal bones of that side

Lambdoid suture

arches across the posterior surface of the skull connecting the occipital bone with the parietal bones

Coronal suture

attaches the frontal bone to the parietal bones

Sagittal suture

extends from the lambdoid suture to the coronal suture, between the parietal bones

the skullcap is made up of the

frontal, occipital and parietal bones

Wormian bones are

small, flat, irregular shaped bones between the flat bones of the skull. There are individual variations in the number, shape, and position of the sutural bones
