What lobe of the cerebrum are the association centers for hearing and smelling located?
The association centers for hearing are located in the temporal lobe, specifically in an area called the auditory cortex. The association centers for smelling, on the other hand, are located in the olfactory bulb and olfactory cortex, which are part of the frontal and temporal lobes.
Olfactory sensations usually fade rapidly as a result of what?
Olfactory sensations usually fade rapidly due to sensory adaptation. This occurs when receptors in the nose become less responsive to a constant smell over time, allowing us to detect changes in our environment rather than being overwhelmed by one smell.
What is the difference between olfactory nerve and optic nerve?
The olfactory nerve is responsible for transmitting sensory information related to smell from the nasal cavity to the brain, while the optic nerve carries visual information from the retina of the eye to the brain. The olfactory nerve consists of sensory nerve fibers that detect odor molecules, whereas the optic nerve is composed of ganglion cell axons that convey light signals. Additionally, the olfactory nerve is unique in that it bypasses the thalamus, directly connecting to the olfactory bulb in the brain. In contrast, the optic nerve passes through the thalamus before reaching the visual processing centers in the occipital lobe.
Where does an olfactory stimulus travel to?
An olfactory stimulus travels from the nasal cavity to the olfactory epithelium, where odor molecules bind to olfactory receptors. The activated receptors send signals through the olfactory bulb, which then relays the information to various brain regions, including the olfactory cortex and the limbic system. This pathway allows for the perception of smell and its emotional or memory associations.
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.

Olfactory nerve filaments are found?
in the olfactory bulb
What cranial nerve is used when smelling a flower?
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
Impulses that stimulate the olfactory receptors are transmitted along the?
Olfactory nerve to the brain's olfactory bulb, where they are processed and interpreted as specific smells. The olfactory nerve is responsible for carrying information about odors from the nose to the brain.
What is in charge of your olfactory system?
The mechanism of the olfactory system can be divided into a peripheral one, sensing an external stimulus and encoding it as an electric signal in neurons, and a central one, where all signals are integrated and processed in the central nervous system. The peripheral olfactory system receptors are connected to bipolar olfactory receptor neurons in the olfactory epithelium. Fot the central olfactory system, axons from the olfactory sensory neurons converge in the olfactory bulb.

What is a good sentence with olfactory?
Olfactory makes you smell stuff
Where are olfactory receptors located?
Olfactory receptors are located in the nasal cavity, specifically in the olfactory epithelium. This specialized tissue lines the upper part of the nasal cavity and contains millions of olfactory receptor cells that are responsible for detecting smells.
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.
A fracture of the ethmoid bone would 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.
