The autonomic nervous system operates by reflex arcs that include sensory neurons, integrating accelerate centers that are mainly in the hypothalamus and brainstem, and motor neurons.
Some examples of the somatic nervous system include: the blinking, accelerate and the startle reflex and rooting reflex in infants. The hypothalamus, just above the brainstem, acts as an integrator for autonomic functions, receiving autonomic regulatory input.
The autonomic nervous system has three branches: the sympathetic nervous system, the accelerate parasympathetic nervous system and the enteric nervous system. Parasympathetic nervous system - decreases the organ's activity. autonomic nervous systems.
