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:
“But the wise know that foolish legislation is a rope of sand, which perishes in the twisting; that the State must follow, and not lead the character and progress of the citizen; the strongest usurper is quickly got rid of; and they only who build on Ideas, build for eternity; and that the form of government which prevails, is the expression of what cultivation exists in the population which permits it.”
—Ralph Waldo Emerson (1803–1882)
“You see, my dear, it occurred to me that he’d make a delightful coffin follower. That, that expression of melancholy. It’s very interesting, don’t you think so, my love?”
—Vernon Harris (c. 1910)
“Fashion is the most intense expression of the phenomenon of neomania, which has grown ever since the birth of capitalism. Neomania assumes that purchasing the new is the same as acquiring value.... If the purchase of a new garment coincides with the wearing out of an old one, then obviously there is no fashion. If a garment is worn beyond the moment of its natural replacement, there is pauperization. Fashion flourishes on surplus, when someone buys more than he or she needs.”
—Stephen Bayley (b. 1951)
