Study Notes
Knee Muscles and Movements
- Knee Muscles: Biceps femoris, Semi-membraneux, Semi-tendineux, Vastus externus, Rectus femoris, Vastus internus, Gracilis
- Rotational Movements:
- Lateral Rotation: Biceps femoris participates in lateral rotation.
- Medial Rotation: Specific muscles are not listed for medial rotation in the table.
- Flexion: Biceps femoris, Semi-membraneux, and Semi-tendineux all participate in knee flexion.
- Extension: Vastus externus, Rectus femoris, and Vastus internus all participate in knee extension, as does the biceps femoris on its proximal portion. Gracilis also plays a role.
- Additional Notes: The Table shows 'X' indicating involvement. Biceps femoris flexes the hip but extends the knee, whereas the vastus externus extends the knee.
