8. Hamstrings 3 Muscles Semimembranosus Semitendinosus Biceps Femoris
Location: Posterior Thigh
Action: Knee FLEXION

9. Hamstrings

10. Pes Anserine Conjoined tendon of three muscles
Sartorius (Hip Flexor)
Gracilis (Adductor)
Semitendinosus (Hamstring)
Location: Anterior medial aspect of tibia

11. Pes Anserine Function: These three muscles all help with knee FLEXION
Adds stability to medial knee

12. Iliotibial Band (IT) Band
Long tendon of the TFL and part of gluteus maximus
Function: Adds stability to the lateral knee
