Few simple experiments prove logically that voluntary (those which 'contract' at will) skeletal muscles of the spine or the lower limbs play very little role in maintaining the erect posture. Yet the body stands upright so there must be other muscle fibres, which we cannot control at will, that keep it that way.

These muscle fibres get their information from the posture and balance centres in the subconscious brain. Impulses from these centres must be maintaining the equilibrium of posture as the burden of carrying out this function is too much to handle for the conscious mind. The latter is so specialised in its functions that it carries out the higher psychic, intellectual and voluntary activities only. Nature has not loaded it with the additional responsibilities of carrying out routine and mundane functions or activities like gait, posture, digestion, breathing etc. If that had happened the conscious brain would have had very little energy or capacity to make decisions. Nature thus separated the conscious and subconscious brain, providing separate circulatory systems and entrusting them with different functional roles.
