autonomic nervous system - Coggle Diagram

- - - - postganglionic in the sympathetic chain or prevertebral ganglia
  - - - the preganglionic fiber descend down into an area near the ganglion
    - - preganglionic come from T1-T4 and synapse within the ganglia and postgabglnic fibers travels via the cardiac veins to the cardiac, pulmonary and esophageal plexus
    - - preganglionic fiber reach the sympathetic chain and then ascend up until it finds a ganglion near C1-C8 and then the postganolic fiber come and synapse and enter to the spinal nerve through grey ramus communicants
    - - the preganglionic fibers from T5-L2 they will synapse and then travel through splanchnic nerves to the target organs
    - - preganglionic fibers through the white ramus communicants and postganglionic through the grey ramus communicants and then to the organs
      - anterior and posterior regions
    - - from T8-L2
        
        the preganglionic fibers will go through the thoracic splanchnic nerves into the adrenal medulla and release carcholomines
- - - - postganglionic they are near the organs
