Olfactory dysfunction: assessment. The olfactory neurons are in the olfactory epithelium. Fully referenced neurology checklist.

Anatomy of the olfactory system

  • The olfactory neurons are in the olfactory epithelium
  • The neurons form the fila olfactoria (nerve bundles)
  • These pass through the cribriform plate into the cranium
  • They connect with olfactory bulb glomeruli neurons
  • The olfactory bulbs project to the olfactory cortex
  • The primary olfactory region includes the piriform cortex
  • The secondary olfactory areas include the hippocampus
