Paraneurology

 

This is the study of paraneurons

Paraneurons were described by Fujita in 1976 as endocrine brothers of neurons.  By this he meant that they paraneurons had some morphological similarities with neuron. He described the following similarities

  • Origin from neural crest
  • Circumnuclear Golgi
  • Presence of neurofilaments and its associated neurofilament protein (NFP)
  • Presence of brain derived tubulin

Some of these cells are also APUD cells

Paraneurons include adrenal medullary cells, insulin-producing cells, C- cells of the thyroid gland etc. Most of these cells produce peptide hormones.
