While sensory systems provide us with information about our own bodies and the environment, systems of motor allow us to interact with this environment. Every movement, that is as simple, is achieved through very complex mechanisms most often [ 130 ].
Indeed, at every moment, the systems we'll see: pyramidal, extra-pyramidal and cerebellar will synchronize their actions to produce a smooth and correct movement [ 3 ].
The pyramid system is at the heart of voluntary actions, the extra-pyramidal system is composed of circuits and beams that allow to automate movements and the cerebellum ensures coordination and correction.
The autonomic nervous system as the name suggests is not subject to voluntary control. It is supported by both sides of sympathetic and parasympathetic control various internal organs to adapt their operations to different situations to which the organization may be exposed.
Reflexes are shortcuts engines also beyond the control of the will, they allow us to avoid a threat even before marking, which is very often vital.
The autonomic nervous system and reflexes are a bit special since they require both sensory as well as motor components.
