in order for you to smell something, molecules have to make it to your nose. everything you smell is gives off molecules. whether good or bad. they are volatile (easy to evaporate) chemicals that float through the air into your nose. at the top of your nose are neurons which recive the moleclues. They have hair-like projections called cila. an odor molecule binds to these cilia to trigger the neuron and cause you to perceive a smell.
What else can I help you with?
What structure transmits information about odors?
The olfactory bulb is the structure in the brain that receives and processes information about odors transmitted from the olfactory receptors in the nasal cavity. This information is then further processed in the brain's olfactory cortex, allowing us to perceive and identify different smells.
What part of the brain is thought to regulate the emotional response to odors?
The amygdala is the part of the brain that is thought to regulate the emotional response to odors. It plays a key role in processing and associating emotional responses with olfactory stimuli.
Odors and subliminal scents that can influence how the brain develops what you remember and how you learn are called?
Pheromones
Why do different substances have unique odors?
Different substances have unique odors because of their specific chemical composition. Each substance releases molecules that interact with our olfactory receptors in different ways, creating distinct smells that our brain interprets as unique odors.
How does a human nose function?
The human nose functions by detecting and processing odors in the air we breathe. The nose contains specialized cells that detect specific odors, sending signals to the brain for interpretation. The nasal passages also help filter, warm, and humidify the air before it reaches the lungs.
What causes people to detect odors?
People detect odors because sensory receptors located in the nose carry smell sensations to the brain. The receptors, which are nerve cell endings, are found in the mucous membrane in the roof of the nose.
What action begins with the nose?
Smelling begins with the nose, as it is the primary organ responsible for detecting odors and sending signals to the brain for interpretation.
Why do different substances have different odors?
Different substances have different odors because of their unique chemical compositions. When molecules from a substance enter the nose, they interact with olfactory receptors, which send signals to the brain that are interpreted as specific smells. The specific arrangement of atoms in a molecule determines its scent, leading to the wide variety of odors we perceive in different substances.
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 are olfactory receptors?
Olfactory receptors are sensory nerve cells located in the nose that detect odors in the environment. They send signals to the brain, which processes these signals to identify different smells. Olfactory receptors play a crucial role in the sense of smell.
What animals besides skunks have odors?
Stinkbugs have odors.
Bleach and drain odors?
Does bleach eliminate drain odors
