How does one smell?
When you breathe in through your nose, air carries tiny odor molecules to special cells in your nasal cavity. These cells send signals to your brain, which interprets them as different smells. This process is known as olfaction.
How does a human nose function?
The human nose functions by detecting and processing odors in the air we breathe. The nose contains specialized cells that detect specific odors, sending signals to the brain for interpretation. The nasal passages also help filter, warm, and humidify the air before it reaches the lungs.
Describe the origin and pathway of an impulse that results in smell?
Smell is a chemical sense detected by sensory cells called chemoreceptors. When an odorant stimulates the chemoreceptors in the nose that detect smell, they pass on electrical impulses to the brain which then interprets patterns in electrical activity as specific odors and olfactory sensation becomes perception.
In what cells does a smell impulse begin?
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
What area of the brain interprets smalls?
The olfactory bulb in the brain, which is part of the limbic system, is responsible for interpreting smells. It processes signals sent by receptor cells in the nose and then transmits this information to other areas of the brain for further processing and perception of smell.
Can you lose brain cells if you smell food?
no you can't.... , you'll only loose brain cells if you ever smell something that's ver toxic.
What path does smell messages take from the nose to the brain?
the smell travels to the olfactory cells, near the top of the nose. when these cells detect the smell, the cells send specific electrical impulses to the brain, which are then interpreted by the lobe of the brain, located under the skull fissure
How does smell travel through the air to reach our noses?
Smell travels through the air as tiny molecules released from objects or substances. These molecules move through the air and enter our noses when we breathe in, where they are detected by special cells in our nasal cavity that send signals to our brain, allowing us to perceive the smell.
Dogs have 220 million olfactory cells so they do what better than humans?
When you reference olfactory cells, you are talking about the sense of smell. These nerve cells transmit what you smell to your brain so that it can decipher what it is you are smelling. There are so many smells though, and a person's olfactory cells cannot capture all of them nor can your brain decipher all of them. In a dog however, they have many, many more of these cells and a larger part of their brain is dedicated to their sense of smell. In short, they can smell a LOT better than we can.
Does the brain smell like blue cheese?
No, the brain does not have a specific smell like blue cheese. The brain is mostly composed of fats, proteins, and nerve cells, which do not emit a smell when intact. Any scent associated with the brain would likely only be noticeable if there was decay or damage.
How does one smell?
When you breathe in through your nose, air carries tiny odor molecules to special cells in your nasal cavity. These cells send signals to your brain, which interprets them as different smells. This process is known as olfaction.
How does the sense of smell communicate with the brain?
Olfactory cells act as sensors Transmit signals via the nervous system to the brain
How does a human nose function?

Why does a person lose sense of smell after suffering a traumatic brain injury?
It depends on which part of the brain was injured - not all people lose their sense of smell. If the part of the brain that controls that sense is injured, then you will lose the ability because the brain cells are damaged and don't work to report smells like they used to.
Which nerve carries impulses from the cells that detect smells?
The olfactory nerve carries impulses from odor-detecting cells to the brain.

Why do you have a cavity?
So that you can breathe and smell
