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.
Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline). [1] Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. Cartilaginous joints also forms the growth regions of immature long bones and the intervertebral discs of the spinal column.
Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the fewest cells so it has the most intercellular space. Fibrous cartilage is found in the spine and the menisci.
The joints are covered by two different kinds of cartilage; the sacral surface has hyaline cartilage and the iliac surface has fibrocartilage. [2] The SIJ's stability is maintained mainly through a combination of only some bony structure and very strong intrinsic and extrinsic ligaments. [5] The joint space is usually 0.5 to 4 mm. [6]
The skeletal portion of the system serves as the main storage system for calcium and phosphorus and contains critical components of the hematopoietic system. [3] This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide stability to the body.
The sternum is a long, flat bone that forms the front of the rib cage. The cartilages of the top seven ribs (the true ribs) join with the sternum at the sternocostal joints. The costal cartilage of the second rib articulates with the sternum at the sternal angle making it easy to locate. [9] The manubrium is the wider, superior portion of the ...
The sternum (pl.: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest.It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.
The hip bone is formed by three parts: the ilium, ischium, and pubis. At birth, these three components are separated by hyaline cartilage. They join each other in a Y-shaped portion of cartilage in the acetabulum. By the end of puberty the three regions will have fused together, and by the age 25 they will have ossified.
