Knee Dissection Lab – KEY
1. Was your pig knee a right or left Knee ? You should
have been able to figure it out.
2. Give at least two or three landmarks (positional
structures) that helped you determine your answer to
question #1.
The patella is on the anterior (front) side of the knee, and the
fibula is always to the lateral (outside) of the leg. The head
of the femur always points medially toward the socket of the
Coxal bone.
3. For each of the following structures, identify the
structure on your pig knee (or diagrams), then state
which bone each structure belongs to.
A)
Lateral Malleolus : FIBULA
B) Greater Trochanter : FEMUR
C)
Medial Malleolus : TIBIA
D)
Main Head of the ball and socket joint: FEMUR
E) Lateral Condyles : On FEMUR and on TIBIA
F) Medial Condyles : On FEMUR and on TIBIA
4. Check off each structure that you could locate.
A)
Patella : X
B) LCL – Lateral Collateral Ligament : X
C)
MCL – Medial Collateral Ligament : X
D)
ACL – Anterior Cruciate Ligament : X
E) PCL – Posterior Cruciate Ligament: X
F) Tibial Lateral Meniscus : X
G)
Tibial Medial Meniscus : X
H)
Femoral Articular Cartilage : X
5. Using your hands describe the following:
A)
Tensile Strength of Ligaments : Extremely strong
and flexible but not stretchy.
B) Articular Cartilage : Very smooth and slippery.
6. The key similarities and differences between a human
knee and a pig knee.
They are very similar (homologous) in that they have
the same bones and ligaments and cartilage. They
differ in that the shapes and lengths of some of these
structures are a bit different.
