There are two principal ones, namely: (i) The anterior or great,also called the bregma and sometimes the sinciput; this space is diamond- orkite-shaped, and is found at the point of junction of the frontal, coronal, andsagittal sutures. It persists during labor, notwithstanding its somewhat de-creased extent caused by the approach of the cranial bones. Four suturesrun into it; it averages one inch in diameter and varies widely in size in differentfetal heads. (2) The posterior or small fontanelle, triangular in shape, is foundat the point of junction of the lambdoidal and sagittal sutures. This spacedoes not persist during labor, being then merely a depression or obliterated by the occiput by the parietal bones. Three lines of sutures run intoit. Not infrequently by reason of advanced ossification this fontanelle is absent. 412 PHYSIOLOGICAL LABOR.
