  • What is the name of this muscle, and what action does it perform?
    Tensor fascia latae, Hip: flexion, abduction, medial rotation, Knee: extension
  • What is the name of this bone? Is it the posterior or anterior side of the body? What is the name of the bone marking labelled number 14?
    Tibia, anterior, tibial tuberosity
  • Classification of tibiofemoral joint and its movement
    Synovial, biaxial, condyloid; flexion/extension, internal/external rotation (unlocking)
  • Name this bone. Is it the posterior or the anterior view? Identify the highlighted bone marking
    Femur, posterior (intercondylar fossa/notch - distal; lesser trochanter), lesser trochanter
  • What is the name of this bone? Is it from the right or left side of the body? What is the name of the bone marking labelled number 11?
    Femur (distal end), left (anterior, patellar surface locates on lateral side); Patellar surface
  • What is the name of this muscle, and what action does it perform?
    Visible Body - Gluteus maximus; extension, lateral (external) rotation, abduction of the thigh at the hip joint
  • Name all of hip extensors
    Visible body app -  Gluteus maximus, Bicep femoris (long head, semitendinosus, semimembranosus, adductor magnus
  • What is the function of the highlighted ligament in the image?
    Pubofemoral ligament, limits extension, abduction and external rotation
  • Identify the joint in the image (name, classification, articular surface, movement)
    Hip joint; synovial, multiaxial, ball and socket; acetabulum and head of femur; flex-extend-ab/dduction, medial/internal rotation
  • Name of the highlighted muscles, and its action
    Biceps femoris, Hip joint: extension (long head); knee joint: lateral rotation, knee flexion
  • Name of all knee flexor
    Visible body app: Hamstring group (Biceps femoris, semitendious, semimembranosus), gracilis, sartorius, gastrocnemius, popliteus
  • Identify the highlighted joint (name, classification, movement)
    Sacroiliac joint; synovial, multi axial, plane, nutation and counternutation
  • Biomechanical function of menisci
    • withstand load bearing forces • increase contact area at the tibiofemoral joint • reduces stress at the joint surfaces • assist in movement of femoral condyle
  • What is the name of this muscle, and what action does it perform?
    Rectus femoris; Hip joint: flexion; knee joint: extension
  • Which muscles are responsible for knee extension, and which of them act only on one joint?
    Visible body app - Quadricep femoris (rectus femoris, vastus lateralis-medialis/intermedius), tensor fascia latae; vatus lateralis/medialis/intermedius
  • Name of the 2 highlighted ligaments and its function
    Fibular collateral (limits extension, prevents adduction); Tibial collateral (limits extension and prevent adductions)
  • Can you name the three highlighted coloured regions in this image?
    Red: ilium, yellow: pubis, green: ischium
  • Name the highlighted joint (classification, amount of movement)
    Pubic symphysis, Fibrocartilaginous joint, little to no movement
