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:
“Our minds can go no further. The human imagination is capable of no further expression of beauty than the carved owl of Athene, the archaic, marble serpent, the arrogant selfish head of the Acropolis Apollo.”
—Hilda Doolittle (1886–1961)
“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)
“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)
