olfactory epithelium n.
Pseudostratified epithelium that contains olfactory, receptor, and nerve cells whose axons connect with the olfactory bulb of the brain.
They subsequently become very pronounced (fig. 309), serving greatly to increase the surface of the olfactory epithelium.
At a very early stage the olfactory nerve attaches itself to the olfactory epithelium.
As is seen, it is difficult to see any connection between these folds of olfactory epithelium and the simple tube of the scorpion.
