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]
However, subsequent research has disproven this belief. The Poisson’s ratio of articular cartilage has been measured to be around 0.4 or lower in humans [11] [14] and ranges from 0.46–0.5 in bovine subjects. [15] The mechanical properties of articular cartilage are largely anisotropic, test-dependent, and can be age-dependent. [11]
In anatomy, a joint capsule or articular capsule is an envelope surrounding a synovial joint. [1] Each joint capsule has two parts: an outer fibrous layer or membrane, and an inner synovial layer or membrane.
The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland.
Articular cartilage: the bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of the joint end of the bone with a smooth, slippery surface that prevents adhesion; articular cartilage functions to absorb shock and reduce friction during movement.
An articular cartilage defect that initially may be small still has the potential to have a physical and chemical "domino effect" on the surrounding "normal" articular cartilage. [2] Pitkin et al. (2014) discovered a potential etiology for articular cartilage damage. When the interarticular transmission of pressures is interrupted so that ...
In the adult the articular surface is about 12 cm 2 (1.9 sq in) and covered by cartilage, which can reach a maximal thickness of 6 mm (0.24 in) in the centre at about 30 years of age. Owing to the great stress on the patellofemoral joint during resisted knee flexion, the articular cartilage of the patella is among the thickest in the human body.
Arthroscopic image of a central triangular fibrocartilage complex (TFCC) tear. X-ray: X-rays of the wrist are made in two directions: posterior-anterior (PA) and lateral. Radiographs are useful to diagnose or rule out possible bone fractures, a positive ulnar variance or osteoarthritis. The TFCC is not visible on an X-ray, regardless of its ...
