Question

1) When discussing the Symathetic nervous system, where is the cell body of the pre-ganglionic neuron for the urinary bladder? Where does its axon travel to? What neurotransmitter is released into the synapse?
2) Answer the same questions from #1 but this time discussing the post-ganglionic neuron (cell body, axon, neurotransmitter, etc.)
Hint: Feel free to answer with a diagram, if helpful. 1) When discussing the Symathetic nervous system, where is the cell body of the pre-ganglionic neuron for the urinary bladder? Where does its axon travel to? What neurotransmitter is released into the synapse?

Explanation / Answer

1). In case of sympathetic nervous system, the cell body of the pre-ganglionic neuron for the urinary bladder is located in the spinal cord (lower thoracic and upper lumbar vertebrae, T10-L2). The axon travels to the ganglia of the pelvic plexus and  inferior mesenteric ganglion. The neurotransmitter released at ganglia is acetylcholine (acts on nicotinic type of ACh receptors), a post ganglionic synapse, the neurotransmitter released is noradrenaline (acts on adrenergic receptors).
