Divisions of the Autonomic Nervous System
Parasympathetic division originate in brainstem and sacral. Synapses in ganglia near effector organ. Long pre-ganglionic and short postganglionic organs, neurotransmitter is acetylcholine and the effectors organs ae salivary glands, digestive and reproductive organs.
Sympathetic division originates in the thoracolumbar segments of the spinal cord. Synapses in ganga near the spinal cord. Short pre-ganglionic and long postganglionic neuron. The neurotransmitters are epinephrine and norepinephrine and the effects organs are the eyes, lungs and heart.
