The olfactory bulb is actually a tiny lobe of the brain.
There are many thousands of different cell types in the olfactory bulb, each with receptors for different chemicals. When these receptors bind to their matching chemical in the air they become excited and trigger a nearby olfactory nerve cell.
Details of what happens after this have yet to be worked out, but basically the firing of these nerve cells is analyzed by nerve circuits in the rest of the olfactory bulb then transferred to the brain, where we call it "smell".
What else can I help you with?
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 are the cells that detect smell called?
chemoreceptor.
What are Olfactory receptor cells are essential for our sense of?
Olfactory receptor cells are essential for our sense of smell, as they are specialized neurons located in the nasal cavity that detect airborne odor molecules. When these molecules bind to the receptors on the olfactory cells, they generate electrical signals that are transmitted to the olfactory bulb in the brain. This process allows us to perceive and identify different odors, playing a crucial role in flavor perception, memory, and even emotional responses. Overall, olfactory receptor cells are vital for our interaction with the environment through the sense of smell.
What are the nerve cells that react to gases?
Olfactory receptor neurons are nerve cells that react to gases, specifically in the context of the sense of smell. These neurons are located in the olfactory epithelium in the nasal cavity and are responsible for detecting various odors in the environment.
Which is the only special senses receptor that can be replaced?
The olfactory receptor cells in the nose are the only sensory receptors that can be replaced throughout life. This neurogenesis allows for the continual renewal of these cells to help maintain our sense of smell.
What special cells allow you to smell food?
Olfactory receptor cells are the receptors for smell.
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 is sensorys receptor for smell?
The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
What are the cells that detect smell called?
chemoreceptor.
What cells provide for the sense of smell?
Olfactory receptor cells located in the nasal epithelium are responsible for detecting smells. When odor molecules bind to these receptor cells, they trigger a signal that is sent to the brain for interpretation.
Which cell detect the smell?
Olfactory receptor cells, located in the nose's olfactory epithelium, are responsible for detecting smells. These receptor cells bind to specific odor molecules and send signals to the brain to process and identify different scents.
How do people smell food?
A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)

What is a nose receptor cell?
An olfactory receptor cell is a specialized cell of the mucosal lining of the nose . These specialized cells serve as the receptors for smell.
What are the nerve cells that react to gases?
Olfactory receptor neurons are nerve cells that react to gases, specifically in the context of the sense of smell. These neurons are located in the olfactory epithelium in the nasal cavity and are responsible for detecting various odors in the environment.
What is the sensory receptors for smell?
The olfactory receptor is found in the nose.
Which of these activates an olfactory receptor and causes the transmission of information about a smell?
An odorant molecule binds to the olfactory receptor, which triggers a signaling cascade leading to the transmission of information about the smell to the brain.
