What is the pathway of smell from the olfactory receptors to the brain?
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 type of nerve conducts impulses to the olfactory bulbs?
The olfactory nerve, also known as cranial nerve I, conducts impulses from the nose to the olfactory bulbs in the brain. It is responsible for the sense of smell.
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
Nerve impulses are received and transmitted to the cell body by?
Nerve impulses are received and transmitted to the cell body by dendrites, which are branched structures that extend from the cell body. Dendrites receive signals from other neurons or sensory receptors and transmit this information to the cell body for integration and processing.
Where does the olfactory nerve end?
The olfactory nerve, responsible for the sense of smell, ends in the olfactory bulb located in the brain, specifically in the olfactory cortex. This is where the nerve impulses triggered by odors are processed and interpreted.
What impulses are transmitted by the sense of smell?
The sense of smell transmits impulses that are related to detecting chemicals in the environment, such as odors and scents. These impulses are then processed by the brain to identify and interpret the various smells, triggering emotional responses and memories.
Impulses carried by the olfactory nerve are for the sense of?
Impulses carried by the olfactory nerve are for the sense of smell.
Process of smelling?
So, we just learned this in anatomy. You breathe in an odogen. The odogen binds with protein receptors in the olfcatory cilium. A potential travels on an axon the olfactory receptor cells synapsing in the olfactory bulb. Then the filaments of the olfactory nerve synapses with mitral cells causing impulses to flow from the olfactory bulbvia the olfactory tracts.
What stimulates sensory impulses at receptors?
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.
What is the nerve for smell?
The olfactory nerves are cranial nerves( arise from the brain ). olfactory nerve is the first nerve among the all cranial nerves. olfactory nerves passes sense of smell through nerve impulses( chemical=neurotransmitters, and electrical signals ).

What cranial nerve carries smell impulses to the brain?
The olfactory nerve, also known as the first cranial nerve, transports impulses for sense of smell to the brain. The olfactory nerve is capable of regeneration.
What type of nerve conducts impulses to the olfactory bulbs?
The olfactory nerve, also known as cranial nerve I, conducts impulses from the nose to the olfactory bulbs in the brain. It is responsible for the sense of smell.
What path does smell messages take from the nose to the brain?

Which nerve carries impulses from the cells that detect smells?
The olfactory nerve carries impulses from odor-detecting cells to the brain.
What nerve carries impulses from the nose?
Olfactory Nerve
Nerve impulses are received and transmitted to the cell body by?
Nerve impulses are received and transmitted to the cell body by dendrites, which are branched structures that extend from the cell body. Dendrites receive signals from other neurons or sensory receptors and transmit this information to the cell body for integration and processing.
