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:
“A wicked mortal is not the idea of God. He is little else than the expression of error. To suppose that sin, lust, hatred, envy, hypocrisy, revenge, have life abiding in them, is a terrible mistake. Life and Life’s idea, Truth and Truth’s idea, never make men sick, sinful, or mortal.”
—Mary Baker Eddy (1821–1910)
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“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)
