This is a diagram from years past that I could not bear to let go. I scanned it and pseudocolored it in photoshop highlighting the olfactory bipolar sensory cells (pink), the basal cells (blue-green) the sustentacular cells (blue) and put in one microvillar cell (yellow) which wasn’t in the original diagram but needed to be added since the migrating immune cells in the olfactory epithelium – and many other epithelia, such as intestine and epidermis, is almost 10% of the cell population. Mitochondria are colored yellow and green, I didn’t pseudocolor the sensory cilia atop the olfactory sensory bipolar cells, nor the knob but probably should have.  This is a raster file-I tried unsuccessfully to vectorize it and i guess there was something that prevented the process, or at least made it beyond my abilities to bring about.
