What does articular surface mean?
A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement.
Where is the patellar surface?
knee joint
The patella is also known as the kneecap. It sits in front of the knee joint and protects the joint from damage. It is the largest sesamoid bone in the body, and lies within the quadriceps tendon….Patella.
| Type | Sesamoid bone |
|---|---|
| Parts | Apex (pointing inferiorly), medial and lateral borders, base (lies proximally) |
Where is the articular cartilage on the patella?
The underside of the patella is covered with articular cartilage, the smooth, slippery covering found on joint surfaces. This covering helps the patella glide in a groove made by the thighbone, or femur called the patellofemoral grove.
What is an example of an articular surface?
simple joints – when two articulation surfaces meet (e.g. shoulder joint) compound joints – when three or more articular surfaces are involved (e.g. radiocarpal joint) complex joints – when 2 or more articular surfaces and an articular disc or meniscus are involved (e.g. knee joint)
What does articular mean in medicine?

What is dog patella?
The patella, or ‘kneecap,’ is normally located in a groove on the end of the femur (thigh bone) just above the stifle (knee). Therefore, a luxating patella is a kneecap that moves out of its normal location. Pet owners may notice a skip in their dog’s step or see their dog run on three legs.
What is the purpose of the kneecap?
The kneecap provides leverage for your muscles as they bend and straighten the leg. It also protects the knee joint.
What is articular cartilage in knee?
Articular cartilage is the dense, fibrous cartilage cap that covers the ends of bones within the joint. In the knee, articular cartilage covers the lower end of the femur (thigh bone), the upper end of the tibia (shin bone), and the undersurface of the patella (knee cap).
What is the purpose of the articular cartilage?
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction.
What are the articular surfaces of the joints?
The joint is surrounded by an articular capsule that defines a joint cavity filled with synovial fluid. The articulating surfaces of the bones are covered by a thin layer of articular cartilage. Ligaments support the joint by holding the bones together and resisting excess or abnormal joint motions.
What is the articular surface of femur?
