Is costal cartilage fibrocartilage?
costal cartilage a bar of hyaline cartilage that attaches a rib to the sternum in the case of true ribs, or to the immediately above rib in the case of the upper false ribs. fibrous cartilage fibrocartilage.
Is costal cartilage articular or non articular?
Compared to articular cartilage, costal cartilage was more densely populated with chondrocytes, rendering it an excellent chondrocyte source. In terms of tissue engineering, using the self-assembling process, costal chondrocytes formed articular cartilage-like neocartilage.
What are the costal cartilages?
Medical Definition of costal cartilage : any of the cartilages that connect the distal ends of the ribs with the sternum and by their elasticity permit movement of the chest in respiration.
Is costal cartilage rigid?
It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body.
What type of cartilage is articular cartilage?
hyaline cartilage
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
What is a costal groove?
costal groove. the groove on the inner surface of the inferior border of the body of the rib. it accommodates the intercostal neurovascular bundle; the costal groove provides a protective function for the intercostal neurovascular bundle, ribs 1-7. “true” ribs – those which attach directly to the sternum.
Is costal cartilage a joint?
The costochondral joints are the joints between each rib and its costal cartilage. They are primary cartilaginous joints. These joints represent the demarcation of the unossified and ossified part of the rib 1.
Which tissue forms ligaments and tendons?
Dense connective tissue
Dense connective tissue is what makes up tendons and ligaments and consist of a higher density of collagen fibers.
