Neurons of the olfactory pathway
1st order neuron - bipolar olfactory neurons in the nasal cavity
2nd order - mitral cells in the olfactory bulb
The course step 1
1st order neuron is located in the olfactory region of nasal cavity
The course step 2
from there, the pathway travels via olfactory nerves and enter the olfactory bulb
course step 3
2nd order neuron located in the olfactory bulb
course step 4
pathway continues as the olfactory tract to the olfactory trigone
course step 5
some fibres continue to medial stria and other to the lateral stria.
