Document Summary
Bipedal locomotion: morphology and biomechanical principles: many features long assumed to suggest knuckle-walking behaviors. Are found in non-knuckle-walking primates: adaptations to bipedalism occurred long before any significant brain expansion or evidence of stone tool making, biomechanics of bipedalism. Challenge of supporting and propelling the body while balancing the center of mass atop two legs. Center of mass (com) a point in space representing the mean location of all mass in an object. Hold our trunks vertically, with our com directly above. Effective mechanical advantage the ratio of a muscle, r, to the moment arm, r, of the ground reaction force vector, with respect to a given joint. Decreasing the amount of muscular effort needed to. Forward position of foramen magnum in the skull. Com slightly behind hip joint when standing still. Lordosis the curve in the human lumbar spine. Iliofemoral ligament ligament that runs from the anterior inferior spine of the ilium to the proximal femur.
