What is an example of Sutural bone?
There are six types of bones in the human body: long, short, flat, irregular, sesamoid and sutural….Bone Shape Classifications.
| Shape | Description | Example |
|---|---|---|
| sutural bones | Small bones located between flat bones of the skull at the suture | Wormian bones of skull (small irregular bones embedded in a cranial suture) |
What type of bone is Sutural?
Sutural bones or Wormian bones (WBs) are irregularly small bones found at the sutures of the skull. They vary in number, shape and size among different population.
Where would you find a Sutural bone in the body?
Sutural bones are only found in the skull. They are the small islands of bone that form if two of the major cranial bones do not completely join during the formation of the cranial sutures in the first months of a baby’s life. Their number and locations vary from individual to individual.
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 is a Sutural joint?
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.
How many sutural bones are in the body?
[12,24] The number of sutural bones is generally limited to two or three, but more than a hundred have been found in the cranium of an adult hydrocephalic skeleton.
What does Sutural mean?
a. The process of joining two surfaces or edges together along a line by sewing. b. The material, such as thread, gut, or wire, that is used in this procedure.

Who has wormian bones?
In our population, wormian bones were found in 53% of children (n = 320): 43% of the children had between one and three (n = 260), 10% had four or more (n = 60), and 6% had five or more (n = 40).
Does everyone have Sutural bones?
They are found in both sexes as well as in both sides of the skull. Approximately half of Sutural bones are located in the lambdoid suture and fontanel and the masto-occipital suture. The second most common site of incidence (about 25%) is in the coronal suture.
Which of the following is an example of a syndesmosis?
Syndesmoses are joints in which the bones are connected by a band of connective tissue, allowing for more movement than in a suture. An example of a syndesmosis is the joint of the tibia and fibula in the ankle. The amount of movement in these types of joints is determined by the length of the connective tissue fibers.
