Anatomy Of Synovial Joint

Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint. Our movable joints are also lubricated and filled with fluid known as synovial fluid and this is why we call this joint as synovial joint.

Types of synovial joints.

Anatomy of synovial joint. The six types of synovial joints allow the body to move in a variety of ways. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. Fibrous joint joined by dense regular connective tissue that is rich in collagen fibers.

This fluid filled space is the site at which the articulating surfaces of the bones contact each other. Synovial joints are the most common type of joint in the body figure 1. The articular surfaces of plane synovial joints are more or less plane.

The bursal fluid exuded by the. Structure and elements of synovial joints the synovial bursas are closed thin walled sacs lined with synovial membrane. Synovial joint not directly joined the bones have a synovial cavity and are united by.

Facet joint. These are plane joints that provide for only limited motions between the vertebrae. The six types of synovial joints are pivot hinge condyloid saddle plane and ball and socket joints figure 943.

Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint. B the hinge joint of the elbow works like a door hinge. The articular surface of the movable joint and has a smooth lining called cartilage.

Types of synovial joints. Accessory structures of a synovial joint. The six types of synovial joints are pivot hinge condyloid saddle plane and ball and socket joints.

Bursas are found between structures that glide upon each other and all motion at diarthroses entails some gliding the amount varying from one joint to another. 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. Structures of a synovial joint key structures of a synovial joint.

There are four structural classifications of joints. Pivot joints are formed by a central bony pivot surrounded by an osteo ligamentous. Smooth cartilage allows friction less movement and this smoothness is further enhanced by body lubricants.

Synovial joints have a rich supply from articular nerves. The three main features of a synovial joint are. In addition to being held together by the intervertebral discs adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints facet joints see figure 93.

The accessory ligaments are separate ligaments or parts. Cartilaginous joint joined by cartilage. In these joints the articular surfaces are pulley shaped.
