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.
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 coloured with the toluidine blue, in wich you can observe a strong metachromasia of the ground substance. View through optical microscope, 40x magnification. Metachromasia (var. metachromasy ) is a characteristic change in the color of staining carried out in biological tissues , exhibited by certain dyes when they bind to ...
Type II collagen is the basis for hyaline cartilage, including the articular cartilages at joint surfaces. It is formed by homotrimers of collagen, type II, alpha 1 chains. It makes up 50% of all protein in cartilage and 85–90% of collagen of articular cartilage. Type II collagen is organised into fibrils.
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
The thyroid cartilage is a hyaline cartilage structure that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple. [1] In the midline above the prominence is the superior thyroid notch.
Hyaline cartilage is named after its glassy appearance on fresh gross pathology. [3] On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage.
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 ...
