Question 6

What are some of the difference of the SNS

Answer 6

1. adrenal medulla has no post-synaptic neutron
2. preganglionic connects to postganglionic for all effectors except adrenal gland
3. preganglionic to chromatin cell in adrenal gland (adrenal medulla)
4. pre to post ganglionic neuron releases Ach
5. postganglionic neuron to effector organ releases NE except adrenal gland
6. NE acts at specialized receptors
