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 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 would a chemical be considered if a person lacks a particular receptor site on the cilia of the olfactory neurons?
The chemical would be considered as odorless to that person because without the specific receptor site on the cilia of the olfactory neurons, the individual would be unable to detect or perceive the smell of the chemical.
How do receptor neurons help people perceive smells?
Receptor neurons in the nostrils first detect an odor by coming into contact with and reacting to gas molecules of the substance. Then the receptor neurons send information about the odor along the olfactory nerve to the brain.
What is another name for receptor cells?
Neurons
Where are olfactory receptor cells located?
They are specialised neurons in direct communication with the olfactory lobe in the brain. They differ from other neurons in having exposed receptor sites in the nasal mucosa that bind to various odoriferous chemicals. When a specific chemical binds to its appropriate receptor site, the neuron foires, releasing the chemical which may well trigger a lot more neurons. This way the brain can distinguish what smells are important. The system is poorly developed in man, but the dog has 100,000 times more receptors than we have. That's why drug sniffing dogs can find your stash so easily... Partial answer: they are found in the nose, they serve to smell and identify smells, and they play a significant role in the taste of food.
What is the minimum number of neurons required to carry information from a sensory receptor to the somatosensory cortex?
At least three neurons are required to carry information from a sensory receptor to the somatosensory cortex. The first neuron is located in the sensory receptor, the second neuron is in the spinal cord or brainstem, and the third neuron is in the thalamus before reaching the somatosensory cortex.
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.
When you smell what kind of neurons are involved?
The sense of smell uses sensory neurons.
What happen when receptor is stimulated?
When a receptor is stimulated it triggers impulses in other neurons....hope this was helpful and correct
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 is the receptor for smell?
