Final answer:
The cranio-sacral division is another term for the parasympathetic nervous system, based on the location of its central neurons.
Step-by-step explanation:
The cranio-sacral division of the autonomic nervous system is also known as the parasympathetic nervous system. The term 'carnio-sacral system' or 'carnio-sacral outflow' is an alternate name for the parasympathetic division of the autonomic nervous system, reflecting the anatomical location of the central neurons in the brain-stem nuclei and the lateral horn of the sacral spinal cord. This division handles 'rest and digest' functions of the body, which is the state of conservation and restoration of energy.
