What is a articular in anatomy?
Definition of articular : of or relating to a joint articular cartilage.
What is a articular surface in anatomy?
ANATOMY. Articular surfaces are formed by specialized hyaline cartilage, which provides a wear-resistant, low-friction lubricated surface that is compressible and elastic and accommodates enormous forces of compression and shear during weight bearing and muscle action.
What are the three types of articulations?
The 3 Types of Joints in the Body
- Immovable (Fibrous) Joints.
- Slightly Movable (Cartilaginous) Joints.
- Freely Movable (Synovial) Joints.
What is articular cartilage in anatomy and physiology?
Articular cartilage is the 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 (Figure 1).
What does Articularis mean?
Meaning of articularis in English a Latin word meaning “articular ,” used in the names of muscles that join with a joint. For example, the articularis cubiti muscle is a muscle of the elbow.
What are the 4 main bones?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.
What are the articular surfaces of the joints?
The shape of articular surfaces of bones helps define the motions available for a joint. Articular surfaces of two bones forming a joint are usually concave on one bone and convex on the other bone. Some articular surfaces are flat. Occasionally adjacent bones are convex on both joint surfaces.
What type of cartilage is articular cartilage?
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
Where is articular cartilage located?
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.
What joints have articular cartilage?
Articular cartilage is found only in diarthroidal joints (synovial joints), and is comprised of hyaline cartilage – a particularly smooth type of cartilage which allows for easy articulation, increased weight distribution, and shock absorption.
What is the function of the articular system?
The muscular system is being used because the muscles are attached to the bones that are being used which provides the movement for the activity. The articular system is being used because the joints are being lubricated so that movement can occur.
What do joints have an articular capsule?
Definition / Description. The functions of articular cartilage in synovial joints include: Reduces friction – helped by its coating of synovial fluid: As the load on the joint increases the spongy cartilage absorbs water, increasing the proportion of lubricating hyaluronic acid in the lubricating film.
Which joint has a fibrous articular capsule?
The articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly.
What is articular surfaces make up the shoulder joint?
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. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless,…
