Why did we choose this topic?• Students have trouble understanding the knee joint• It pulls the muscular and skeletal systems together• It shows the function of both systems• It applies the functions of different connective tissues• APR provides animations for action, a good animation
on synovial joint, and attachments in dissection view• It helps students deduce what happens (show
attachment on anterior, based on that they can say whether it would be extension or flexion)
Definition and Overview
• Synovial joints– Definition– Parts– Classifications

• Add muscle and bone tissues after other histology slides– Skeletal muscle tissue– Compact bone tissue
