Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint. The six types of synovial joints are pivot, hinge, condyloid, saddle, plane, and ball-and socket-joints (Figure 9.4.3).

7 wrz 2024 · The three main features of a synovial joint are: (i) articular capsule, (ii) articular cartilage, (iii) synovial fluid. Articular Capsule. The articular capsule surrounds the joint and is continuous with the periosteum of articulating bones. It consists of two layers:
There are six such classifications: hinge (elbow), saddle (carpometacarpal joint), planar (acromioclavicular joint), pivot (atlantoaxial joint), condyloid (metacarpophalangeal joint), and ball and socket (hip joint).
This section will examine the anatomy of selected synovial joints of the body. Anatomical names for most joints are derived from the names of the bones that articulate at that joint, although some joints, such as the elbow, hip, and knee joints are exceptions to this general naming scheme.
Based on the shape of the articulating bone surfaces and the types of movement allowed, synovial joints are classified into six types. At a pivot joint, one bone is held within a ring by a ligament and its articulation with a second bone. Pivot joints only allow for rotation around a single axis.
24 lut 2023 · List the six types of synovial joints and give an example of each. Synovial joints are the most common type of joint in the body (Figure 9.5.1 9.5. 1 ). A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity.
30 paź 2023 · Synovial joints are the freely mobile joints in which the articulating surfaces have no direct contact with each other. The movement range is defined (i.e., limited) by the joint capsule, supporting ligaments and muscles that cross the joint. Most of the upper and lower limb joints are synovial.
