Some examples of secondary cartilaginous joints in human anatomy would be the manubriosternal joint (between the manubrium and the body of the sternum), intervertebral discs, and the pubic symphysis. Articulating bones at a symphysis are covered with hyaline cartilage and have a thick, fairly compressible pad of fibrocartilage between them.
Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers.
A spotted gar larva at 22 days stained for cartilage (blue) and bone (red). Chondrogenesis is the biological process through which cartilage tissue is formed and developed. . This intricate and tightly regulated cellular differentiation pathway plays a crucial role in skeletal development, as cartilage serves as a fundamental component of the embryonic skele
The synovial joints will form between the adjacent cartilage models, in an area called the joint interzone. Cells at the center of this interzone region undergo cell death to form the joint cavity, while surrounding mesenchyme cells will form the articular capsule and supporting ligaments.
Hyaline cartilage is the glass-like and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs , nose, larynx , and trachea . [ 1 ] Hyaline cartilage is pearl-gray in color, with a firm consistency and has a considerable amount of collagen.
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.
Joint pain is a common symptom we all experience at some point or another. Painful joints can have a significant impact on quality of life and the ability to do daily activities.
Articular cartilage is the connective tissue that protects bones of load-bearing joints like knee, shoulder by providing a lubricated surface. It deforms in response to compressive load, thereby reducing stress on bones. [4] This mechanical responsiveness of articular cartilage is due to its biphasic nature; it contains both the solid and fluid ...
