where are olfactory receptors located in human body
Olfactory receptor In vertebrates, the olfactory receptors are located in both the cilia and synapses of the olfactory sensory neurons[4] and in the epithelium of the human airway.[5]  In insects, olfactory receptors are located on the antennae and other chemosensory organs.[6] Sperm cells also express odor receptors, which are thought to be involved in chemotaxis to find the egg cell.[7]
