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.
Why are olfactory bulbs on humans smaller than on sheep?
Humans rely more on other senses, like vision, for survival compared to sheep, which heavily rely on their sense of smell for identifying predators and finding food. Thus, sheep have larger olfactory bulbs to process a greater amount of olfactory information.
Olfactory bulbs areas of the brain located just above the sinus cavity and just below the frontal lobes that receive information have at least olfactory receptors?
The olfactory bulbs are areas of the brain located at the base of the frontal lobes that receive information from olfactory receptors in the nose. They play a crucial role in processing smells and transmitting this information to other brain regions involved in perception and memory.
What cranial nerve doesn't pass through the thalamus?
CN 1 does not pass thru, from what I read. It's the only one.
Which lobes of the brain receive input from the nose?
My mom is a good person so nares go to brain to realize that she could have bought me flowers.
Does the rat or human have bigger olfactory bulbs?
Rats have larger olfactory bulbs relative to their brain size compared to humans. This is because rats heavily rely on their sense of smell for navigation, communication, and food detection in their environment.
What brain is similar to a sheeps brain?
Human Brains are similair in structure to a sheeps brain, sheep have larger olfactory bulbs though, sheeps brains are also not a large as humans.
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.
Olfactory bulb sheep brain vs human brain?
olfactory bulbs larger in sheep like the rat we dissected as well because of the need for heightened sense of smell for food, predators etc. these defense and survival mechanisms are more needed in sheep than humans.
How do olfactory bulbs work during puberty?
The olfactory bulbs are a part of the brain involved in odor/taste. In antomical studies of animals such as dogs ,cat, rats, mouse which have a much greater reliance on sense of smell, the olfactory bulbs ate much larger in portion to the whole brain. This heightened sense of smell is used by these species for the detection of pheromones, and other chemical triggers given off by the other sex of the species. In humans, who rely so much less on the sense of smell, the olfactory bulbs serve a much smaller role in mating/reproduction. While it has yet to be determined if humans even produce significant pheromones, certain odors can have sexual responsive effects, but this is limited often to individuals and not the whole human race. While olfactory bulbs may increase in relative size during puberty in humans, it is unclear what significance this may have.
Can brain damage affect the olfactory nerve?
Yes, brain damage can affect the olfactory nerve, which is responsible for the sense of smell. Damage to specific areas in the brain, such as the olfactory bulbs or frontal lobes, can lead to changes in the sense of smell or loss of smell altogether. In cases of traumatic brain injury or diseases that affect the brain, the olfactory nerve can be impacted resulting in olfactory dysfunction.
Why are olfactory bulbs on humans smaller than on sheep?
Humans rely more on other senses, like vision, for survival compared to sheep, which heavily rely on their sense of smell for identifying predators and finding food. Thus, sheep have larger olfactory bulbs to process a greater amount of olfactory information.

What are the Inhibitory cells in the olfactory bulbs called?
The inhibitory cells in the olfactory bulbs are called granule cells. They are involved in regulating the activity of the mitral and tufted cells, which are the principal output neurons in the olfactory bulb. Granule cells help shape and refine olfactory information processing in the brain.
What is the function of olfactory lobs?
The olfactory lobes, also known as the olfactory bulbs, are responsible for processing and interpreting sensory information related to smell. They receive signals from the olfactory receptors in the nose and help to identify different odors. This information is then sent to the brain for further processing and recognition.
What is the most anterior portion of the leopard frog brain?
The most anterior portion of the leopard frog brain is the olfactory bulbs. These structures are responsible for processing information related to smell and play a key role in the frog's sense of smell and chemoreception.
Sheep brain compared to human brain?
A human brain is larger overall, sheep brains have larger olfactory bulbs though, they also have an area on the sides, around where the temporal lobe is where their eyes go, this causes an indentation humans don't have.
