Document Summary
Locomotory adaptation in horses: barrel-shaped trunk: supports the fermentation chamber long skinny legs: move the animal swiftly, with stamina and with energy efficiency, work together well (functionally integrated of correlated" parts) Horses legs: very mobile and built for: speed- long and rapid strides (legs are energetically extensive to use because we swing them back and forth, stamina energy efficient motion, standing fatigue resistance at rest. Inertia of a rotating body with respect to its rotation. The equine hoof: modified nail co-opted as a weight-bearing component of the musculoskeletal system. Major problem with long bones fractures can occur easily. Horses don"t have 5 fingers/toe, they only have 1 toe: splint bone (small bone in the foreleg of the horse) = reduced metacarpal, makes the shaft of. Metabolic energy usage the hammer easier to swing: walk: slow gate, lower metabolic cost, trot: jog trot, slightly higher metabolic cost than walk, gallop: spring, metabolic cost increases.
