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 is the cell called in the nose?
The cells responsible for our sense of smell are called neurons, specifically olfactory receptor neurons. They are linked directly to the brain, and respond to different chemical signals to generate what we then perceive as smells and odors.
What are the olfactory membranes?
The olfactory membranes are located in the upper part of the nasal cavity and contain olfactory receptors responsible for detecting odor molecules. These receptors send signals to the brain, allowing us to perceive different smells.
Receptor cells for your sense of reproduce themselves every week or two?
Receptor cells for the sense of smell typically reproduce themselves every 30 to 60 days in humans. This continuous turnover helps maintain the sensitivity of the olfactory system to various odors.
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.
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)

A fracture of the ethmoid bone could result in damage to which cranial nerve?
Olfactory nerve. Olfactory nerve fibers arise from olfactory receptor cells located in olfactory epithelium of nasal cavity and pass through cribriform plate of ethmoid bone to synapse in olfactory bulb.
What type of nerve cells receives stimuli for the sense of small?
Olfactory nerves, definetly. We're studying this currently in my grade.
What molecule is activated from the binding of an odorant to transmembranous receptor molecules on olfactory hairs?
The molecule activated from the binding of an odorant to transmembrane receptor molecules on olfactory hairs is called cyclic AMP (cAMP). When an odorant binds to the receptor, it triggers a signaling cascade that leads to the production of cAMP, which ultimately stimulates the olfactory sensory neuron and initiates the sense of smell.
Which sense organ has olfactory cells that allow oneself to detect an odor?
The nasal canal is made up of olfactory cells that allow you to detect odors.
What structures are the receptors for the sense of smell?
The receptors that actually bind with the molecules that we smell are called Olfactory receptor neurons. They pass their signal through the caribform plate, then down the olfactory nerve, and finally to the olfactory bulb in the brain.
