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 · Key Structures of a Synovial Joint. 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:
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.
Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity.
Learning Objectives. By the end of this section, you will be able to: Describe the structural features of a synovial joint. Discuss the function of additional structures associated with synovial joints. 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 ([link]).
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.
. Click to View Larger Image. A need for strength makes the bones rigid, but if the skeleton consisted of only one solid bone, movement would be impossible. Nature has solved this problem by dividing the skeleton into many bones and creating joints where the bones intersect.
