What is an example of a Wormian bone?

Examples of the Wormian bones (marked by asterisks) located within the lambdoid suture of the human skull; Oc — occipital bone, Lp — left parietal bone, Rp — right parietal bone. Wormian bones are irregular ossicles of small size and reveal fractal pattern of their edges.

What does Wormian bone mean?

Wormian bones are small bones that are often found within the sutures and fontanelles of the skull. When a child presents an unexplained fracture or fracture(s), osteogenesis imperfecta is usually suggested when an “abnormally high number” of fractures are seen.

What is an example of a Sutural bone?

The patella of the knee is an example of a sesamoid bone. Sutural bones are small, flat, irregularly shaped bones. They may be found between the flat bones of the skull. They vary in number, shape, size, and position.

Where are Sutural bones found?

Sutural bones are sporadically found in the course of cranial sutures and fontanels or isolated. They are supernumerary irregular, accessory and abnormal small bones interposed between cranial bones, most commonly located in the lambdoid suture.

Where would you look for Wormian bones?

Wormian bones are abnormal ossicles that develop from extra ossification centers within the cranium. They are most frequently located in the lambdoid suture or the coronal suture, and have been seen in the fontanelles, particularly the posterior fontanelle.

What are the short bones?

Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone. Short bones are located in the hands and feet. The patella (kneecap) is also considered a short bone.

Is a flat bone?

Flat bones are bones whose principal function is either extensive protection or the provision of broad surfaces for muscular attachment. These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage….

Where is the Bregma?

The bregma is the midline bony landmark where the coronal and sagittal sutures meet, between the frontal and two parietal bones.

Which bone is known as isolated bone?

Wormian bones, also known as intrasutural bones or sutural bones, 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.
