Skeletal System: Joints Assigned Readings: Chapter 8 (pp. 223-229; 241-245) Lecture Outline I. Introduction to Articulations A. What is a joint/articulation: a sites where two or more bones meet B. Joints give our skeleton mobility and hold it together II. Classification of Joints A. Functional classification is based on the amount of movement allowed at the joint. 1. Synarthroses: immovable joints – skull, have sutures that connect bones together permanently, fibrous connective tissue hold the two parts together 2. Amphiarthroses: slightly movable joints - pubic symphysis – held together by cartilage instead of fibers 3. Diarthroses: freely movable joints – knee, elbow B. Structural classification focuses on the material binding the bones 1. Fibrous joints: bones are joined by fibrous tissue; lack a joint cavity – skull sutures 2. Cartilaginous joints: bones are joined by cartilage; lack a joint cavity – pubic symphysis 3. Synovial joints: bones are separated by a fluid-containing joint cavity
