Solution
The correct option is C Is a craniosacral division of the autonomic nervous system
The human sympathetic nervous system controls the functions (for example accelerated heartbeat, reduced digestion rate etc) that help prepare the organism for the physical strain which is required to escape from a dangerous situation.The preganglionic fibres of sympathetic nervous system arise from thoracic lumbar portion of spinal cord and immediately terminate in ganglia lying near the cord. Under stress conditions, preganglionic neurons of this system release acetylcholine which in turn makes postganglionic neurons to release norepinephrine causing increased heart beat.Sympathetic nervous system is thoracic lumber division of autonomous nervous system. The parasympathetic system is its sacral divisionSo, the correct answer is 'Is a craniosacral division of the autonomic nervous system'
