    Study Notes

    Quadruped Mode of Locomotion

    • Combination of brachiation and quadrupedal movement.
    • Includes knuckle or fist-walking techniques.

    Quadruped Skull Anatomy

    • Characterized by a large face and small braincase.
    • Nuchal plane is large and faces backward.

    Quadruped Dental Anatomy

    • Features c/p3 honing complex with protruding canines, sectorial P3, and diastema.
    • Incisors are relatively large.
    • Dental arcade has a u-shaped configuration.

    Quadruped Hip Anatomy

    • Sacro-iliac joint positioned distantly from the hip joint.
    • Ilium is long, narrow, and oriented backward.
    • Gluteal muscles are responsible for rotation and extension.

    Quadruped Knee Anatomy

    • Femur is oriented vertically.
    • Lateral condyle of distal femur appears round in side view.
    • Lacks a prominent lateral lip on the distal femur.

    Quadruped Hand Anatomy

    • Features elongated hands and fingers while having a short thumb.

    Quadruped Foot Anatomy

    • Feet are flat, flexible, and lack an arch.
    • Hallux (big toe) is opposable.
    • Lateral toes are comparatively long.

    Biped Mode of Locomotion

    • Primarily involves bipedal movement.

    Biped Skull Anatomy

    • Description includes a small face and large braincase.
    • Nuchal plane is small and oriented downward.

    Biped Dental Anatomy

    • Absence of c/p3 honing complex.
    • Incisors are relatively small.
    • Dental arcade forms a parabolic shape.

    Biped Hip Anatomy

    • Sacro-iliac joint is positioned closer to the hip joint.
    • Ilium is short, broad, flares outward, and faces sideways.
    • Gluteal muscles are mainly involved in abduction.

    Biped Knee Anatomy

    • Femur angles inward towards the knee joint.
    • Lateral condyle of distal femur is elliptical in lateral view.
    • Well-developed lateral lip of the distal femur.

    Biped Hand Anatomy

    • Proportional balance between thumb and other fingers.

    Biped Foot Anatomy

    • Feet are rigid with a longitudinal arch.
    • Hallux is non-opposable and aligned with other toes.
    • Lateral toes are short.
