Q

3 ways a neuron can synapse:

A
  1. at the same level
  2. you can synapse up or down a level
  3. axon follows the same pathways by bypasses ganglia all together and to a collateral ganglion which makes it a splanchnic nerve

Q

comes from the CNS comes out through the ventral root bc its motor, goes through white communicans, synapses and sends message out through gray communicans
