Synovial joints are further classified into six different categories on the basis of the shape and structure of the joint. They allow movement across multiple axes. atlanto-axial and. Articular surfaces are flat (plane). It allows movement across transverse axis (flexion and extension). One of the articular surface is a condyle (convex) and the other is reciprocally concave. Each is maximally convex in a particular direction and is maximally concave at right angles to this direction. Nearly all joints of the limbs and most joints of the body fall into this class. e.g. We will begin by looking at these six types in simple terms, but then see that this is an imperfect classification for … Following are the characteristic features of a typical synovial joint: Following are the seven different types of synovial joints according to the axis of movement and shape of articular surfaces. Three Categories of Functional Joints. Most of the upper and lower limb joints are synovial.. Notify me of follow-up comments by email. 1st carpometacarpal and sternoclavicular joints. –. Try this amazing Types Of Synovial Joints! Bicondylar joints are predominantly uniaxial, with the main movement in one plane, but with limited rotation about a second axis orthogonal to the first. e.g. Rotation around the third axis is largely prevented by general articular shape. Articular surface covered with hyaline cartilage. Synovial Joints. Example-Interphalan- geal joints of the fingers and toes. elbow, One of the articular surface is oval-shaped and convex and the other is reciprocally elliptical and concave. General Anatomy of Synovial Joints . Synovial joints are the most common type of joints in your body. A dislocation is complete separation of articular surfaces of bones forming a joint. Elbow joint (humerus, radius and ulna) and knee joint ( femur, tibia and patella). A synovial joint is one among the three types of joints, which are classified based on structure and is the most common type of joint in the human body. The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints (Figure 9.4.3).Figure 9.4.3 – Types of Synovial Joints: The six types of synovial joints allow the body to move in a variety of ways. Synovial joints are places where bones articulate with each other inside of a joint cavity. Ball and socket joints. Each differs depending on the shapes of the articular surfaces and the movements that are allowed. The shape of the joint affects the type of movement permitted by the joint. The functional classification of body joints is based on the degree of movement found at each joint. Biaxial; allow greater freedom of movement than condyloid joints; each articular surface has both concave and convex areas; e.g thumb joint. 3 Synovial. Articular surfaces are flat (plane).

They allow only gliding/sliding movement. SYNOVIAL JOINTS Synovial Synovial joint Synovial joints have a space between the articulating bones for synovial fluid. The different subtypes of joints are balland socket, hinge, pivot, ellipsoidal or condyloid, saddle, and gliding or planar. e.g. One of the articular surface is a globular head and the other is like a socket. atlanto-axial and superior radioulnar joints. They have varying shapes, but the important thing about them is the movement they allow. Saddle joints. The reverse of approximation is separation. Required fields are marked *. Ligaments are capsular or accessory. shoulder joint, hip joint. Primary movements occur in two orthogonal planes. Intercarpal joints, intertarsal joints, One of the articular surfaces is like a central pivot(peg) and the other is an osseocartilagenous ring. At a synovial joint, the articulating surfaces of the bones are not directly connected, but instead come into contact with each other within a joint cavity that is filled with a lubricating fluid. The skeletal system has a number of different joint types, for example there are fibrous joints and there are cartilaginous joints.
