Cardiac plexus

• Cardiac plexus of the Sympathetic Chain
  • Divided into deep and superficial
  • Parasympathetic
    • Cardiac branches of the Vagus Nerve
  • Sympathetic
    • Cervical ganglia
      • Superior cervical cardiac nerve (a visceral branch of the Superior cervical ganglia)
      • Middle cervical cardiac nerve (a visceral branch of the Middle cervical ganglia)
      • Inferior cervical cardiac nerve (a visceral branch of the Inferior cervical ganglia or cervicothoracic ganglion; a.k.a. Stellate ganglion)
    • Thoracic cardiac nerves (branches of the upper four or five thoracic sympathetic ganglia).
    • Cervical and thoracic cardiac nerves contain post-ganglionic sympathetic neurons, which arise from the above-mentioned cervical and thoracic sympathetic ganglia.
