  1. Cluster of nerve cell bodies located outside the brain and spinal cord, i.e., in the peripheral nervous system.
    Note: Ganglia interconnect to form a complex network known as a plexus and serve as relay stations where different neurons can modulate the signals of each other. Compare: basal ganglion.
  2. Fibrous cyst usually attached to a tendon sheath.
