In the olfactory epithelium, which is in turn located high up in the nasal cavity.
Additionally, some odor receptors are present in human sperm, which allow for positive chemotaxis.

What are nasal passages for?
In HUMANS, mucus acts as an important unspecific form of defense against pathogens preventing them from entering your body and coating our stomach walls which prevents the highly acidic acids in our stomach from digesting itself.In ANIMALS, mucus has many roles.defense against predators Ex. hagfishmotion Ex. snailshomes Ex. cave swiftlethunting Ex. New Zealand glowwormbungee (escape) cord Ex. banana slug
What kind of receptors are the olfactory receptors?
the detect smell
How can you smell?
A small amount of the substance gets airborne, and then end up in your nose. In the nose you have specialized cells, a bit like the taste buds on your tongue, and they will react to this substance and send a message to your brain.
What are the organs of smell and the cranial nerves connected to them?
The organ of smell is the nose - more specifically it is a patch of epithelium called the olfactory epithelium located in the roof of the nasal cavity. The cranial nerves associated with smell are the olfactory (I) nerves
Why are taste and smell receptors classified as Chemoreceptors because they both respond to?
Chemoreceptors (chemical receptors) respond to chemicals in food and scents.
Receptors for the sense of smell are located within the?
the olfactory bulb is located above the cribriform plate
What is the nasal passages job?
Lets you smell and filters out germs
What is the sensory organ for smell?
"olfactory" They are chemical receptors, in your nasal sinuses.
How many parts of the nose are there?
There are four known parts of the nose,those are: Nostrils~those are openings in our nose Nasal Cavity~passages where we smell pass Scent Receptors~it is found in the upper part and it recognizes what kind of smell is that and bring it to the brain Trachea/Windpipe~it is also a passage but downwards
What are the functions of the nasal passeages?
Nasal passages are to filter and possibly warm the air breathed in. They also let air in so that the sense of smell can work right.
Which part of the body does a snake use to smell?
The olfactory receptors at the back of the nasal chamber.
Where in the nose are nerves ending for smell located?
In the nasal cavity.
Where in the nose are the nose endings for smell located?
In the nasal cavity.
Is it possible to smell underwater?
No. Unless you're in a Submarine or you're in a container that is complete blocked off from water while submerged in it. In order for you to smell, air must be present so the chemical compounds of what you're trying to smell can move freely. Also your nasal passages must be clear so that the receptors in your nose can receive these compounds. Water completely blocks everything.
Why can't you smell things when you have a cold?
The swelling in your nose or mucus in your nose keeps the air which carries odors from reaching the nerves that detects and registers "smells" to your brain.This also affects taste. 80% of taste is from the nerves (olfactory bulb) high in the nose; while 20% is from the mouth - sweet, sour, etc. This involves what is called "retro" that is - odor molecules travel through your mouth through the back of your throat and up into the nasal area and up to the olfactory bulb. If your nasal passages high in the nasal area are swollen shut you will not smell nor taste. When the infection or cold starts to subside you find that your sense of smell is now too strong due to the nerves becoming irritated. This will also subside. The nerve ending that smell and taste are renewed about every 40 days.
What senses are dependent on chemorecptors?
The two groups of chemoreceptors are the following:1- Central Chemorecepto- In the medulla oblongata, which measures PO2, PCO2 and the pH of CSF. (Cerebral spinal fluid)2- Peripheral Chemoreceptor - Contained in small nodules within the aorta and carotid bodies.
Why can you smell?
We have an olfactory bulb at the base of our brain that has nerve receptors leading into our nasal cavity. When certain particles come in contact with these receptors, the olfactory bulb sends its message to another part of the brain in the limbic region.
