    • divides posterior and medial compartment
  97. Pes Anserine of thigh
    3 Medial, Anterior, Posterior
    • Gracilis- Medial (aDductor group)
    • Sartorius- Anterior (quad group)
    • Semitendinosis- Posterior (hamstring group)
  98. Posterior Thigh Compartment
    BF, Semib, Semit,
    common attachment: ischial tuberosity
    common action: Hip extension, Knee flexion
    all 3 cross 2 joints (hip, knee)
    • Biceps Femoris- Knee flexion, hip extension
    • Semimembranosus- Knee flexion, hip extension
    • Semitendinosus- Knee flexion, hip extension
  99. Biceps Femoris- Posterior hamstring
    • O: ischial tuberosity, lateral linea aspera
    • I: lateral & posterior portion head of fibula
    • Knee flexion, hip extension
    • most lateral hamstring
    • only hamstring attaches to fibula and femur
  100. Semimembranosus- posterior hamstring
    • O: ischial tuberosity
    • I: posterior medial surface medial condyle of tibia
    • Knee flexion, hip extension
  101. Semitendinosus- posterior hamstring
    • O: ischial tuberosity
    • I: medial to tibial tuberosity (pes anserine)
    • Knee flexion, hip extension
    • semitendinosis= long tendon
    • intermediate hamstring
  102. Ankle joint= hinge (synovial-moveable)
    MOvement ankle joint Dorsal, Plantar
    Movement tarsal joint, inversion, eversion
    • Dorsal flexion -top of foot posterior, foot off ground
    • Plantar flexion - bottom foot anterior (point toes)
    • Inversion- bottom foot medial
    • Eversion- bottom footout lateral
  103. Soleus muscle
    • powerful plantar flexion ankle
    • stretch soleus by beanding knee
    • superficial to tibialis posterior
    • attaches to calcaneus via the calcaneal tenson (Achilles heel)
    • crosses the ankle but not knee
  104. Gastrocnemius muscle
    • powerful plantar flexion, knee flexion
    • superficial to plantaris and soleus
    • attaches to calcaneus vis calcaneal tendon
    • crosses both ankle and knee joints
  105. Plantaris
    • plantar flexion (weak) knee flexion (weak)
    • attaches to calcaneus but not via the calcaneal tenson
    • sandwiched between gastrocnemius and solues
    • not a part of calcaneal tenson
