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:
“When I hear the hypercritical quarreling about grammar and style, the position of the particles, etc., etc., stretching or contracting every speaker to certain rules of theirs ... I see that they forget that the first requisite and rule is that expression shall be vital and natural, as much as the voice of a brute or an interjection: first of all, mother tongue; and last of all, artificial or father tongue. Essentially your truest poetic sentence is as free and lawless as a lamb’s bleat.”
—Henry David Thoreau (1817–1862)
“Feminism is hated because women are hated. Anti-feminism is a direct expression of misogyny; it is the political defense of women hating.”
—Andrea Dworkin (b. 1946)
“An unlicked bear”
—Trans. by Johanna Prins.
Dutch expression meaning “a boor”: from the old belief that bear cubs are licked into shape by their mothers.
