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)
“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)
“There exists in a great part of the Northern people a gloomy diffidence in the moral character of the government. On the broaching of this question, as general expression of despondency, of disbelief that any good will accrue from a remonstrance on an act of fraud and robbery, appeared in those men to whom we naturally turn for aid and counsel. Will the American government steal? Will it lie? Will it kill?—We ask triumphantly.”
—Ralph Waldo Emerson (1803–1882)
