Fibrous joint. 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 .
Syndesmosis between ulna and radius of upper arm. A syndesmosis (“fastened with a band”) is a type of fibrous joint in which two parallel bones are united to each other by fibrous connective tissue. The gap between the bones may be narrow, with the bones joined by ligaments, or the gap may be wide and filled in by a broad sheet of ...
CPT is characterized by persistent nonunion because of fractures of the tibia and the presence of fibrous tissue between parts of the fractured bone. The persistent nonunion eventually leads to the formation of a false joint, otherwise known as pseudarthrosis. This pseudarthrosis is a non-healing bone lesion, resulting in reduction of mobility ...
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. This joint unites long bones and permits free bone movement and greater mobility. [1]
Metaphysis. The metaphysis ( pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including ...
The interosseous membrane of the leg ( middle tibiofibular ligament) extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg. It consists of a thin, aponeurotic joint lamina composed of oblique fibers, which for the most ...
Intramembranous ossification is one of the two essential processes during fetal development of the gnathostome (excluding chondrichthyans such as sharks) skeletal system by which rudimentary bone tissue is created. Intramembranous ossification is also an essential process during the natural healing of bone fractures [1] and the rudimentary ...
In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation ). These processes also control the reshaping or replacement of bone following injuries like fractures ...
