4 The complexity of the human foot Why this complexity? Why is the foot not a simple hinged plate? Some complexity can be functionally understood: adaptation to substrate is needed (flexible foot) efficient push-off is also needed (rigid foot) balance
5 The complexity of the human foot The human foot is a very complex structure: 26 bones (+ sesamoids) numerous ligaments numerous intrinsic muscles numerous extrinsic muscles Why this complexity? Why is the foot not a simple hinged plate? Some complexity can be functionally understood: adaptation to substrate is needed (flexible foot) efficient push-off is also needed (rigid foot) balance
6 The complexity of the human foot The human foot is a very complex structure: 26 bones (+ sesamoids) numerous ligaments numerous intrinsic muscles numerous extrinsic muscles Why this complexity? Why is the foot not a simple hinged plate? Some complexity can be functionally understood: adaptation to substrate is needed (flexible foot) efficient push-off is also needed (rigid foot) balance Are all these elements really essential in fulfilling these tasks? Isn t the foot a highly redundant structure?
7 Complexity of the Foot In order to understand foot anatomy, we have to account for two aspects: 1. Function: foot anatomy reflects functional requirements BUT! The foot has not been «engineered» de novo 2. Evolution: foot anatomy reflects its historical background and may show vestigeal remains 1. A structure (in the broad sense) can change (over generations) if there is an adaptive benefit. If there is a cost, or if there is no benefit, they are unlikely to change. Courtesy of dr. K. Août, University of Liverpool
