Hyaline cartilage is the most common kind of cartilage in the human body. [2] It is primarily composed of type II collagen and proteoglycans. [2] Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2]
Endochondral ossification is the process by which most vertebrate axial skeletons form into hardened bones from cartilage. This process begins with a cartilage anlage where chondrocyte cells will congregate and start their maturation process. Once the chondrocytes have fully matured at the desired rate, the cartilage tissue will harden into ...
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
Within adults and developing adults, most chondroblasts are located in the perichondrium. This is a thin layer of connective tissue which protects cartilage and is where chondroblasts help to expand cartilage size whenever prompted to by hormones such as GH, TH, and glycosaminoglycans. [2]
Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage. Perichondrium is a type of irregular collagenous ordinary connective tissue, and also functions in the growth and repair of cartilage. Perichondrium contains type I collagen [1] and type XII collagen. [2]
This hyaline cartilage template expands through both: [8] [9] Interstitial growth Appositional growth Cellular protagonists: Chondrocytes present within the existing cartilage. Chondroblasts that develop from the perichondrium. Mechanism: Chondrocytes proliferate and lay down matrix. Chondroblasts differentiate into chondrocytes and lay down ...
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.
Harvesting of nasal cartilage is minimally invasive, can be performed in an outpatient procedure under local anesthesia and is associated with minimal morbidity. [6] NC can be isolated from nasal septal cartilage biopsies by enzymatic digestion using collagenase type I, II or IV (at different combination and concentration – varying from 0.15% to 0.6% –) alone or after an initial short pre ...
