preganglionic

Examples of preganglionic in the following topics:

• Autonomic Nervous System

  • A preganglionic neuron (originating in the CNS) synapses to a neuron in a ganglion that, in turn, synapses on the target organ .
  • Most preganglionic neurons in the sympathetic nervous system originate in the spinal cord.
  • Parasympathetic preganglionic neurons have cell bodies located in the brainstem and in the sacral (toward the bottom) spinal cord.
  • The axons of the preganglionic neurons release acetylcholine on the postganglionic neurons, which are generally located very near the target organs.
  • In the autonomic nervous system, a preganglionic neuron of the CNS synapses with a postganglionic neuron of the parasympathetic nervous system.
