If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur. [1] This can result in skull deformities. [1] These deformities include: [3] Brachycephaly (both sides) Plagiocephaly (one side only) Oxycephaly (both sides)
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. [ 1 ] Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates .
Side view of the skull Human skull side sutures right. A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey's fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. These joints are synarthroses. [1]
Wormian bones, also known as intrasutural bones or sutural bones, [1] are extra bone pieces that can occur within a suture (joint) in the skull. These are irregular isolated bones that can appear in addition to the usual centres of ossification of the skull and, although unusual, are not rare. [2] They occur most frequently in the course of the ...
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.
In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
If the suture is not present at birth because both frontal bones have fused (craniosynostosis), it will cause a keel-shaped deformity of the skull called trigonocephaly. Its presence in a fetal skull, along with other cranial sutures and fontanelles , provides a malleability to the skull that can facilitate movement of the head through the ...
In human anatomy, the asterion is a visible (craniometric) point on the exposed skull. It is just posterior to the ear. It is the point where three cranial sutures meet: the lambdoid suture. [1] parietomastoid suture. [1] occipitomastoid suture. [1] It is also the point where three cranial bones meet: the parietal bone. the occipital bone.
