In vertebrates, the olfactory receptors are located in the cilia of the olfactory sensory neurons. In insects, olfactory receptors are located on the antennae and other chemosensory organs. Sperm cells also express odor receptors, which are thought to be involved in chemotaxis to find the egg cell.

Famous quotes containing the word expression:
“I do not know whether there be, as a rule, more vocal expression of the sentiment of love between a man and a woman, than there is between two thrushes. They whistle and call to each other, guided by instinct rather than by reason.”
—Anthony Trollope (1815–1882)
“Realism should only be the means of expression of religious genius ... or, at the other extreme, the artistic expressions of monkeys which are quite satisfied with mere imitation. In fact, art is never realistic though sometimes it is tempted to be. To be really realistic a description would have to be endless.”
—Albert Camus (1913–1960)
“We can see nothing whatever of the soul unless it is visible in the expression of the countenance; one might call the faces at a large assembly of people a history of the human soul written in a kind of Chinese ideograms.”
—G.C. (Georg Christoph)
