Expression
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:
“As a man has no right to kill one of his children if it is diseased or insane, so a man who has made the gradual and conscious expression of his personality in literature the aim of his life, has no right to suppress himself any carefully considered work which seemed good enough when it was written. Suppression, if it is deserved, will come rapidly enough from the same causes that suppress the unworthy members of a man’s family.”
—J.M. (John Millington)
“Great speeches have always had great soundbites. The problem now is that the young technicians who put together speeches are paying attention only to the soundbite, not to the text as a whole, not realizing that all great soundbites happen by accident, which is to say, all great soundbites are yielded up inevitably, as part of the natural expression of the text. They are part of the tapestry, they aren’t a little flower somebody sewed on.”
—Peggy Noonan (b. 1950)
“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)
