The olfactory bulb is a small , match-head sized organ in the top of the nasal cavity,and is connected to hundreds of olfactory hairs, or cilia, which lie in a layer of mucous. These have receptor sites, and it is still not well understood how these work, but one theory is that the shape of the molecule (of the substance being smelt) and the way in which it locks onto the receptor determines the impulses sent to the brain. (the bulb is thought of as a direct extension of the brain) If this is true, it may help explain why with prolonged exposure to a smell, you will stop smelling it until you go outside and clear the nose and come back.The receptor sites become saturated with the molcules and stop sending nerve impulses.
What else can I help you with?
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
What are the sensory receptors for smell referred to as?
The sensory receptors for smell are referred to as olfactory receptors.
What receptors sends messages to your brain which allows you to smell?
thalamus (novanet)
What kind of receptors are the olfactory receptors?
Olfactory receptors are specialized sensory receptors responsible for detecting odor molecules in the air. They are located in the olfactory epithelium of the nasal cavity and are involved in the sense of smell.
Olfactory in a human?
The olfactory system in humans is responsible for the sense of smell. It involves receptors in the nose that detect different odors in the environment and send signals to the brain for interpretation. Humans can distinguish between thousands of different smells due to the complex interactions of these olfactory receptors.
What is the relationship between olfactory and gustatory receptors?
Gustatory receptors are part of the sense of taste. They are in your mouth. Olfactory receptors are part of the sense of smell. They are in your nose.
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.
Why is the signal from smell so quick to reach the brain?
Smell signals can reach the brain quickly because the olfactory nerve directly connects the olfactory receptors in the nose to the olfactory bulbs in the brain. This direct pathway allows for rapid transmission of smell information. Additionally, the olfactory system is designed to quickly detect and respond to potential dangers in the environment.
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
What are the sensory receptors for smell referred to as?
The sensory receptors for smell are referred to as olfactory receptors.
Why can you smell?
We have an olfactory bulb at the base of our brain that has nerve receptors leading into our nasal cavity. When certain particles come in contact with these receptors, the olfactory bulb sends its message to another part of the brain in the limbic region.
What are olfactory centers responsive to?
Olfactory centers are responsive to scent molecules that are detected by olfactory receptors in the nose. These receptors then send signals to the brain for interpretation, which allows us to perceive and recognize different smells.
What receptors sends messages to your brain which allows you to smell?
thalamus (novanet)
What kind of receptors are the olfactory receptors?
Olfactory receptors are specialized sensory receptors responsible for detecting odor molecules in the air. They are located in the olfactory epithelium of the nasal cavity and are involved in the sense of smell.
How do olfactory receptors work to make smell possible?
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 are the resources of smell?
The primary resources of smell are chemical molecules that are detected by olfactory receptors in the nose. These molecules are released into the air by substances like food, flowers, and other items. The olfactory receptors then send signals to the brain, where they are interpreted as different odors.
How do smell particles interact with our olfactory system to create the sensation of different scents?
Smell particles, or odor molecules, enter the nose and bind to olfactory receptors in the olfactory epithelium. This triggers a signal to the brain, which interprets the combination of receptors activated as a specific scent. Different combinations of receptors being activated create the sensation of different scents.
