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.
Section from mouse joint showing cartilage (purple) The articular cartilage function is dependent on the molecular composition of the extracellular matrix (ECM). The ECM consists mainly of proteoglycan and collagens. The main proteoglycan in cartilage is aggrecan, which, as its name suggests, forms large aggregates with hyaluronan and with ...
Types of joints based upon their structure (L to R): cartilaginous joint, fibrous joint, and synovial joint. Structural classification names and divides joints according to the type of binding tissue that connects the bones to each other. [1] There are four structural classifications of joints: [8]
Severe trauma may lead to fracture of the costal cartilage. [6] Such injuries often go unnoticed during x-ray scans, but can be diagnosed with CT scans. [6] Surgery is typically used to fix the costal cartilage back onto either the rib or sternum. [6] Costal cartilage may be harvested for reparative use elsewhere in the body.
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.
In cases like this, the body will form a scar in the area using a special type of cartilage called fibrocartilage. [2] Fibrocartilage is a tough, dense, and fibrous material that helps fill in the torn part of the cartilage; however, it is not an ideal replacement for the smooth, glassy articular cartilage that normally covers the surface of ...
The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other. Muscles contract to move the bone attached at the joint.
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.
