A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. [1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage , and from synostosis (ossified junctions), which is the fusion of two or more bones.
The xiphisternal joint (or xiphisternal symphysis) is a location near the bottom of the sternum, where the body of the sternum and the xiphoid process meet. It is structurally classified as a synchondrosis, and functionally classified as a synarthrosis.
Nutritional status of an individual can be a crucial factor in the progression and healing of periodontal tissues. The relationship between oral health and systemic health has become an increasingly important subject. Studies have suggested that vitamins D and C in particular have a certain grade of relationship with periodontal health. However ...
A synovial joint, also known as diarthrosis, joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces.
The articulating surfaces of synarthroses have little or no mobility, and are strongly united to each other. For example, most of the joints of the skull are held together by fibrous connective tissue and do not allow for movement between the adjacent bones. This lack of mobility is important, because the skull bones serve to protect the brain. [3]
A grade I injury is a partial anteroinferior tibiofibular ligament tear, meaning the exorotation and squeeze tests are negative for this grade. Grade II injury is a complete anteroinferior tibiofibular ligament and inferior interosseous ligament tear, meaning that squeeze test and exorotation are positive.
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
An example is the joints of the vertebral column only allow for small movements between adjacent vertebrae, but when added together, these movements provide the flexibility that allows the body to twist, or bend to the front, back, or side.
