Last week's #MysteryAnatomy structure was Hyaline Cartilage.

Hyaline cartilage is a translucent glassy (hyaline) soft tissue found on many joint surfaces throughout the body. Hyaline cartilage is firm in consistency and it contains a considerable amount of collagen. Hyaline cartilage contains no nerves or blood vessels.

Hyaline cartilage can be found in the larynx, trachea, and bronchi as well as on the articulating surfaces of bones. The collagen fibers of hyaline cartilage make structures and joints strong. However the collagen fibers make those same structures less elastic and movable. Hyaline is the most prevalent form of cartilage in the body. Hyaline cartilage consists of cells (chondrocytes) occurring generally in groups of two in an almost homogeneous matrix. It's simple structure makes hyaline cartilage relatively easy to identify for histology and anatomy students.
