In line with the complexity of the functions mediated
by posture, central organization of its control system involves
many interacting elements. On the sensory side,
multisensory (visual, labyrinthine, proprioceptive and
cutaneous) inputs contribute to orienting the postural
segments with respect both to each other and the external
world (vertical gravity vector). These classes of
sensors monitor any mismatch between the intended
and actual positions.
