Presentation transcript:

Joints and Articulations Classify and describe the general structure of a joint.

Classification of Joints Fibrous – joined by fibrous tissue; no joint cavity. Mostly immovable. Cartilaginous- joined by cartilage; no movement. No movement. Synovial – covered with articular cartilage, enclosed within an articular capsule and lined with membrane. Freely movable.

Types Fibrous Joints Sutures, syndesmoses, and gomphoses.

Types of Cartilaginous Joints Synchondroses and symphyses.

Types of Synovial Joints Plane Hinge Ball and Socket Saddle Pivot Condyloid

General Structure of Synovial Joint Five Distinguishing Features Articular Cartilage-covers bone surfaces Joint Cavity- space containing fluid Articular Capsule-2 layers connective tissue Synovial Fluid-reduces friction Reinforcing ligaments- strengthen joint
