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
Animation link
Overview of synovial joints
Question 1
Which of the following describes the knee joint?
A. Pivot
B. Ball and socket
C. Hinge
D. Ellipsoidal
Dense Regular Connective Tissue
v
Fibrocartilage
Dense Irregular Connective Tissue
Hyaline Cartilage
• Add muscle and bone tissues after other histology slides– Skeletal muscle tissue– Compact bone tissue
Question 2
Which of the following is found in synovial joints?
A. Hyaline cartilage
B. Fibrous capsule
C. Synovial membrane
D. All of the above
Knee Joint
Surface projection of patella

• Extension– Muscle tendons/tissues– Origins– Insertion*Histology slides from APR
Surface projection of hamstring tendons
Quadriceps femoris muscle
Insertion of quadriceps femoris muscle
