Only a comparatively small part of the head at term is represented by the face. The rest of the head is composed of the firm skull, which is made up of two frontal, two parietal, and two temporal bones, along with the upper portion of the occipital bone and the wings of the sphenoid. These bones are separated by membranous spaces, or sutures.
The frontal angle is practically a right angle, and corresponds with the point of meeting of the sagittal and coronal sutures; this point is named the bregma; in the fetal skull and for about a year and a half after birth this region is membranous, and is called the anterior fontanelle.
English: The adult skull is normally made up of 22 bones. Except for the mandible, all of the bones of the skull are joined together by sutures, semi-rigid articulations formed by bony ossification, the presence of Sharpey's fibres permitting a little flexibility
Sphenozygomatic suture (blue circle), seen from behind. Side view of the skull. (Sphenozygomatic suture visible at center, between sphenoid bone , which is colored yellow in the diagram, and the zygomatic bone , which is colored in white.).
The inner surface of the skull-cap is concave and presents depressions for the convolutions of the cerebrum, together with numerous furrows for the lodgement of branches of the meningeal vessels. Along the middle line is a longitudinal groove, narrow in front, where it commences at the frontal crest, but broader behind; it lodges the superior ...
Cranial height is defined as the distance between the bregma and the midpoint of the foramen magnum (the basion). [6] This is strongly linked to more general growth. [6] This can be used to assess the general health of a deceased person as part of an archaeological excavation, giving information on the health of a population.
The sphenosquamosal suture is a cranial suture between the sphenoid bone and the squama of the temporal bone. Additional images ... "Anatomy diagram: 34256.000-2".
