In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull, the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses.
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 .
Also known as a "wedge-and-groove" joint, the name is derived from the Greek 'skhindulesis', meaning "to cleave", as in cutting with a stump with an axe. [1] This fibrous suture joint can be found between the vomer and the perpendicular plate of the ethmoid bone as well as between the vomer and the gap between the maxilla and palatine. [2]
The sagittal suture, also known as the interparietal suture and the sutura interparietalis, [citation needed] is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta , meaning arrow .
A synarthrosis is a type of joint which allows no movement under normal conditions. Sutures and gomphoses are both synarthroses. Joints which allow more movement are called amphiarthroses or diarthroses. Syndesmoses are considered to be amphiarthrotic, because they allow a small amount of movement. [1]
The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull. ... "Anatomy diagram: 34256. ...
The frontal suture is a fibrous joint that divides the two halves of the frontal bone of the skull in infants and children. Typically, it completely fuses between three and nine months of age, with the two halves of the frontal bone being fused together.
The frontoethmoidal suture is the suture between the ethmoid bone and the frontal bone. ... "Anatomy diagram: 34257.000-2". Roche Lexicon - illustrated navigator ...
