Then, in 1991, the first olfactory receptors were described.

The olfactory receptor gene family is the largest in the genome.

Further research on human olfaction systems identified 347 olfactory receptors.

In the next section, we'll learn more about olfactory receptors and odorant patterns.

Humans have about 40 million olfactory receptors that detect up to 10,000 different odors.

Basal stem cells create new olfactory receptors through cell division.

Two major classes of olfactory receptors have been identified in humans:

In mammals, olfactory receptors have been shown to signal via G protein.

The released pheromones are received by olfactory receptors on the antennae.

They found that every olfactory receptor cell has only one type of receptor.

In fact, they have molecules that are much the same as olfactory receptors in our noses.

Tiny hairs, made of nerve fibres, dangle from all your olfactory receptors.

For a molecule to trigger olfactory receptor neurons, it must have specific properties.

Each glomerulus collects information from a specific olfactory receptor neuron.

Animals that are capable of smell detect aroma compounds with olfactory receptors.

Odor sensation depends on the concentration (number of molecules) available to the olfactory receptors.

For a moment, Rod envied the robot his ability to cut off his olfactory receptors.

To answer this question, I think we need to look beyond the olfactory receptor genes and consider olfaction in its full behavioral context.

There are millions of olfactory receptor neurons that act as sensory signaling cells.

In insects, olfactory receptor neurons typically reside on the antenna.

In humans, olfactory receptors are categorized in 56 families.

By comparison, only 20 percent of genes in the mouse olfactory receptor gene family are pseudogenes.

Smell begins when airborne molecules stimulate olfactory receptor cells.

The receptors that sense smells are called olfactory receptors.
