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:
“Of course, some men are very effective caregivers [of elderly parents]. But this situation occurs far less frequently for males than females, because it is a role reversal. For women, caregiving is an expected duty; for men, it is an unexpected expression of love or devotion.”
—Tish Sommers (20th century)
“Criticism, that fine flower of personal expression in the garden of letters.”
—Joseph Conrad (1857–1924)
“Surely it is one of the requisites of a tasteful garb that the expression of effort to please shall be wanting in it; that the mysteries of the toilet shall not be suggested by it; that the steps to its completion shall be knocked away like the sculptor’s ladder from the statue, and the mental force expended upon it be swept away out of sight like the chips on the studio floor.”
—Elizabeth Stuart Phelps (1844–1911)
