  1. Objective 9 Compare and contrast the three major categories of joints. Give an example of each.

  2. Joints • Articulations of bones • Functions of joints • Hold bones together • Allow for mobility • Ways joints are classified • Functionally • Structurally

  3. Functional Classification of Joints • Synarthroses – “together joint” • immovable joints, skull • Amphiarthroses – “both side joint” • slightly moveable joints, wrist • Diarthroses – “2 (direction) joint” • freely moveable joints, all movements

  4. Fibrous Joints • Bones united by fibrous tissue • Examples • Sutures • In skull • Between tibia & fibula Figure 5.27a–b

  5. Cartilaginous Joints • Bones connected by cartilage • Examples • Intervertebral joints • Pubic symphysis (pelvis) Figure 5.27d–e

  6. Synovial Joints • Articulating bones are separated by a joint cavity • Synovial fluid is found in the joint cavity Figure 5.24f–h
