Anatomy Of Synovial Joint

There are four structural classifications of joints. The articular surface of the movable joint and has a smooth lining called cartilage.

Human Being Anatomy Skeleton Types Of Synovial Joints

Cartilaginous joint joined by cartilage.

Anatomy of synovial joint. 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. 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. B the hinge joint of the elbow works like a door hinge.

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. Pivot joints are formed by a central bony pivot surrounded by an osteo ligamentous. The articular surfaces of plane synovial joints are more or less plane.

The six types of synovial joints allow the body to move in a variety of ways. Types of synovial joints. The six types of synovial joints are pivot hinge condyloid saddle plane and ball and socket joints.

Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint. Synovial joints have a rich supply from articular nerves. Structures of a synovial joint key structures of a synovial joint.

Structure and elements of synovial joints the synovial bursas are closed thin walled sacs lined with synovial membrane. The three main features of a synovial joint are. These are plane joints that provide for only limited motions between the vertebrae.

A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. Accessory structures of a synovial joint. Types of synovial joints.

Smooth cartilage allows friction less movement and this smoothness is further enhanced by body lubricants. The accessory ligaments are separate ligaments or parts. 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.

This fluid filled space is the site at which the articulating surfaces of the bones contact each other. In these joints the articular surfaces are pulley shaped. The six types of synovial joints are pivot hinge condyloid saddle plane and ball and socket joints figure 943.

Fibrous joint joined by dense regular connective tissue that is rich in collagen fibers. Synovial joint not directly joined the bones have a synovial cavity and are united by. Synovial joints are subdivided based on the shapes of the articulating surfaces of the bones that form each joint.

The bursal fluid exuded by the. Synovial joints are the most common type of joint in the body figure 1. Facet joint.
