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 2.22). Figure 2.22 Types of Synovial Joints The six types of synovial joints allow the body to move in a variety of ways.

The articular capsulesurrounds the joint and is continuous with the periosteum of articulating bones. It consists of two layers: 1. Fibrous layer (outer) – consists of white fibrous tissue, known the capsular ligament. It holds together the articulating bones and supports the underlying synovium. 2. Synovial layer (inner)– a highly vascularised lay...
The articulating surfacesof a synovial joint (i.e. the surfaces that directly contact each other as the bones move) are covered by a thin layer of hyaline cartilage. The articular cartilage has two main roles: (i) minimising friction upon joint movement, and (ii) absorbing shock.
Thesynovial fluidis located within the joint cavity of a synovial joint. It has three primary functions: 1. Lubrication 2. Nutrient distribution 3. Shock absorption. Articular cartilage is relatively avascular, and is reliant upon the passive diffusion of nutrients from the synovial fluid.

Apr 21, 2024 · A joint is a region where 2 bones make contact. Joints may be classified histologically or functionally. Histological classification is based on the predominant connective tissue type composing the joint, either fibrous, cartilaginous, or synovial. Functional classification is based on the amount of movement the joint permits. The 3 functional joint types include the immovable synarthrosis ...

Anatomy of a Joint. Joints are the areas where 2 or more bones meet. Most joints are mobile, allowing the bones to move. Joints consist of the following: Cartilage. This is a type of tissue that covers the surface of a bone at a joint. Cartilage helps reduce the friction of movement within a joint. Synovial membrane.

2.2.2 Synovial Joints. Synovial joints are the most common type of joint in the body (Figure 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. This fluid-filled space is the site at which the articulating surfaces of the bones contact each other.
