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:
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.
The most common type of joint, the synovial joint, features a fluid-filled space between smooth cartilage pads at the end of articulating bones. Surrounding the joint is a capsule of tough dense irregular connective tissue lined with synovial membrane.
The six types of synovial joints allow the body to move in a variety of ways. (a) Pivot joints allow for rotation around an axis, such as between the first and second cervical vertebrae, which allows for side-to-side rotation of the head. (b) The hinge joint of the elbow works like a door hinge.
In this abstract, we will learn about the synovial joints (lat. articulationes synoviales). As already mentioned, their main difference from synarthroses is the presence of an articular cavity , or joint gap (cavitas articularis) .
Discuss the structure of specific body joints and the movements allowed by each. Describe the bones that articulate to form selected synovial joints; Explain the movements available at each joint; Describe the structures that support and stabilize each joint
