The joint range of movement depends on the specific type of diarthroidal joint. Articular cartilage provides a nearly frictionless lubricating load-bearing surface that supports and distributes the forces generated during loading and motion of the diarthrodial joints.
In the following two subsections we discuss the structure and function of articular cartilage and give a broad background to the pathophysiology of arthritis before discussing the links between.
Function of articular cartilage. Articular cartilage is a highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient. A further function of articular cartilage is the ability for that part of the anatomy to move on one or more planes.
The joint range of movement depends on the specific type of diarthroidal joint. Where Is Articular Cartilage Found. Articular cartilage locations are found throughout the body.
What is articular cartilage function. Articular cartilage is a thin layer of specialized connective tissue with unique viscoelastic properties. Its principal function is to provide a smooth lubricated surface for low friction articulation and to facilitate the transmission of loads to the underlying subchondral bone.
Articular cartilage provides a nearly frictionless lubricating load-bearing surface that supports and distributes the forces generated during loading and motion of the diarthrodial joints. The mechanical properties of cartilage are conferred by the tissues extensive extracellular matrix ECM that is maintained by a single population of cells known as chondrocytes. The unique structure of articular cartilage provides the intrinsic functional properties that enable the knee joint to withstand and resist excessive compressive and biomechanical loads facilitating almost frictionless knee movement.
This chapter outlines the architectural and compositional features of articular cartilage. A further function of articular cartilage is the ability for that part of the anatomy to move on one or more planes. The joint range of movement depends on the specific type of diarthroidal joint.
Where Is Articular Cartilage Found. Articular cartilage locations are found throughout the body. The basic science of articular cartilage.
Structure composition and function. The basic science of articular cartilage. Structure composition and function.

Articular cartilage AC covers the ends of bones forming synovial joints and facilitates the transmission of loads across articular surfaces whilst permitting almost friction-free movement and minimizing pressure on the underlying subchondral bone Bhosale and Richardson 2008. In the following two subsections we discuss the structure and function of articular cartilage and give a broad background to the pathophysiology of arthritis before discussing the links between. 6 ARTICULAR CARTILAGE IN HEALTH AND DISEASE Lyn March and Chris Little Chapter objectives After studying this chapter you should be able to.
Understand normal articular cartilage structure and function including the delicate balance between synthesis and catabolism performed by cartilage cells chondrocytes. Appreciate the essential structure and anatomy of the knee joint. One articular cartilage function is to provide smooth and low-friction interaction between the bones of a joint.
This may allow the withstanding of pressure and weight-bearing brought about by the motions of daily and athletic activities. By keeping the bones from gliding against each other it can provide a measure of protection and a surface. There are several reasons for the articular cartilage depending on the location.
Generally though it reduces friction reduces stress on the underlining bone and helps equalize the load bearing pressure. 29k views Reviewed 2 years ago. Articular cartilage is a highly functional tissue which covers the ends of long bones and serves to ensure proper joint movement.
Articular cartilage is a white elastic tissue that allows bones to glide smoothly against each other. It covers the end of the femur and acetabulumThe function of articular cartilage is to absorb. It may be found in the intra-articular lips disks menisci and intervertebral discs and it serves as a transitional tissue between dense connective tissue tendon and hyaline cartilage.
93 This chapter will focus on articular cartilage which is a specialized form of hyaline cartilage. Articular cartilage covers the articulating ends of. Articular cartilage is devoid of blood vessels lymphatics and nerves and is subject to a harsh biomechanical environment.
Most important articular cartilage has a limited capacity for intrinsic healing and repair. In this regard the preservation and health of articular cartilage are paramount to. The function of articular cartilage is dependent on the molecular composition of the extracellular matrix ECM which consists mainly of proteoglycans and collagen.
As mentioned previously the main proteoglycan in cartilage is aggrecan which forms large aggregates with hyaluronan and are negatively charged to hold water in the tissue. Form and function of articular cartilage. Articular cartilage lies at the end of bones at the joint.
It is very smooth its coefficient of friction is less than one-third of ice on ice highly compressible and resilient. Articular cartilage derives its powers from its. The major function of articular cartilage is to create a smooth surface that can resist friction and pressure caused by weight-bearing activities.
It supports the softer tissues of the trachea and helps them to retain an open posture. The articular cartilage ____________ surface area and __________ stress is nearly frictionless. Aiding lubrication and minimizing wear of opposing bone surfaces.
Increasing the surface area and decreasing stress allows the articular cartilage to function in. What are the 4 functions of articular cartilage. Distribute loads over a wide area.
Allow movement of bony surfaces with minimal friction minimal wear improve fit of articular surfaces. Provide lubrication of articular surfaces. Is healthy articular cartilage vascularized.
Cartilage helps keep the trachea open and flexible. Cartilage in the weight-bearing joints such as the vertebrae knees and hips absorb impact from movement and help disperse the body weight. Cartilage cushions all the joints allows gliding movement and reduces friction between bones.
Articular cartilage is the hyaline cartilage. Articular cartilage is 2 to 4 mm thick in length. Articular cartilage is devoid of blood vessels nerves and lymphatics cells.
