The portions of the coronal suture below and above the bend differ somewhat in character.
A similar bend in the coronal suture is present in the same specimen on the left side.
These terminate at the false sutures which themselves begin at the laudal and end at the coronal suture.
Below the junction of the abnormal with the coronal suture, the latter takes a pronounced bend forward.
Trochocephaly (roundness of head) is due to partial synostosis of the frontals and parietals in the centre of the coronal suture.
coronal suture n.
