Bicep Femoris

  • Origin
    • Bicep Femoris (Short Head): Lateral lip of the linea aspera of the Femur
    • Bicep Femoris (Long Head): Ischial Tuberosity
  • Insertion
    • Bicep Femoris (Short Head): Head of the Fibula and lateral condyle of the Tibia
    • Bicep Femoris (Long Head): Head of the Fibula and lateral condyle of the Tibia

Semitendinosus

Semimembranosus


Actions

  • As a muscle group
    • Stabilize the knee
    • Activate at the last quarter of the gait cycle to generate hip extension and resist knee extension
    • Resist anterior translation of the tibia (together with the Anterior Cruciate Ligament) [2]
  • Individually, each muscle has its own role
    • Bicep Femoris (Short Head)
      • Knee flexion and lateral rotation of the tibia
    • Bicep Femoris (Long Head)
      • Knee flexion, lateral rotation of the tibia, and hip extension
    • Semitendinosus
      • Knee flexion, lateral rotation of the tibia, and hip extension
    • Semimembranosus
      • Knee flexion, lateral rotation of the tibia, and hip extension [1]

Artery

  • Deep femoral artery
  • Inferior Gluteal Artery
  • Popliteal Artery
  • Perforating Arteries
  • Semitendiosus
    • Deep Femoral Artery (first perforating branch)
    • Medial Femoral Circumflex Artery
    • Inferior Gluteal Artery
    • Inferior Medical Geniculate Artery
  • Semimembranosus
    • Femoral Artery (perforating branches)
    • Popliteal Artery (perforating branches)
