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:
“No compliment can be eloquent, except as an expression of indifference.”
—George Eliot [Mary Ann (or Marian)
“You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all, just as an intelligence without the possibility of expression is not really an intelligence. Our memory is our coherence, our reason, our feeling, even our action. Without it, we are nothing.”
—Luis Buñuel (1900–1983)
“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)
