- enhancing discrimination between odors.
- enhancing sensitivity of odor detection.
- filtering out many background odors to enhance the transmission of a few select odors.
- permitting higher brain areas involved in arousal and attention to modify the detection or the discrimination of odors.
Olfactory nerves act as transducers - changing chemical signals, as when an odor chemical binds to its receptor at an olfactory dendritic nerve ending, into nerve impulses - that is (i.e.) biological signals. These reside in the mucous membrane.
Nerve fibers leave the olfactory cells and enter the skull through the ethmoid bone, then disappear into the 'olfactory bulb' located at the anterior end of the 'olfactory tract', which then leads to the frontal - and eventually the temporal - lobe of the cerebrum.

Where are olfactory receptors located?
Olfactory receptors are located in the nasal cavity, specifically in the olfactory epithelium. This specialized tissue lines the upper part of the nasal cavity and contains millions of olfactory receptor cells that are responsible for detecting smells.
How much stronger is a cats smell then people?
The olfactory receptor genes map topographically onto the first relay station, a sheet of modules called glomeruli in the olfactory bulb. Up to 80% of the glomerular layer in the rat can be removed without significant effect on olfactory detection and discrimination (Bisulco and Slotnick 2003). If the remaining 20% of the glomeruli-and the olfactory receptor genes they represent-can subserve the functions of 1,100 genes, it implies that 350 genes in the human are more than enough to smell as well as a mouse.

What type of receptors are olfactory receptors?
Olfactory receptors are G protein-coupled receptors (GPCRs). These receptors are located in the olfactory epithelium of the nasal cavity and are responsible for detecting odor molecules.
How are the parts of birds and fish similar in structure and function?
how are parts of birds & fish similar in structure & function
Where are the olfactory receptors located?
Olfactory receptors are located in the olfactory epithelium, which is a specialized tissue found in the upper part of the nasal cavity. These receptors are responsible for detecting and transducing odor signals to the brain for processing.
Function of olfactory tract?
The olfactory tract is a bundle of axons connecting the mitral and tufted cells of the olfactory bulb to several target regions in the brain.
Function of olfactory organ in fish?
if i knew the answer i wouldnt be asking
Olfactory nerve filaments are found?
in the olfactory bulb
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
What is the bony structure between the olfactory epithelium and the olfactory bulb?
Cribriform plate
Impulses that stimulate the olfactory receptors are transmitted along the?
Olfactory nerve to the brain's olfactory bulb, where they are processed and interpreted as specific smells. The olfactory nerve is responsible for carrying information about odors from the nose to the brain.
What are the main functions of a nose?
the nosetrills,nasal cavity,mucus membrame,cilia,olfactory nerves and olfactory bulb.
What is olfactory bulb?
olfactory bulb is related with sense of smell. in human it has small in size but in animals its size is so large. therefore the sense on smell in animals is better then human
Where is the olefactory bulb located?
The olfactory bulb (for the sense of smell) is located in the limbic system of the brain.
Where does the olfactory nerve end?
The olfactory nerve, responsible for the sense of smell, ends in the olfactory bulb located in the brain, specifically in the olfactory cortex. This is where the nerve impulses triggered by odors are processed and interpreted.
Does the olfactory bulb sense temperature and pressure?
NO it has to do with the sense of smell
What is the function of olfactory?
The olfactory lobes are parts of the human brain involved in the perception of smell.
