What is the significance of the fact that the olfactory bulbs are larger in sheep brain than in human brain?

Sheep are more reliant on their sense of smell vs humans who rely more on sights and sounds. It's a ''survival type of thing" for the reason why sheep's olfactory bulbs are larger.
Hope I helped!! :)

∙ 12y agoSheep have a much better sense of smell than humans! As prey animals sheep evolved better smell to warn of advancing predators. Perhaps the sheep also need better smell for social interactions also.
Wiki User
∙ 13y agoThe sheep need a stronger sence of smell that the human, the size of the bulbs provide have it
Wiki User
∙ 13y agoThis means that olfaction is relatively more important to sheep than in humans.
Wiki User
∙ 12y agoIt means that sheep use their sense of smell a lot more than humans do.
Wiki User
∙ 12y agoAs sheep use their sense of smell more than humans.
Wiki User

Wiki User
∙ 12y agobecause we have smaller necks

Why are olfactory bulbs on humans smaller than on sheep?
Olfactory bulbs are smaller in human's because sheep's rely on their sense of smell more than humans do. Where as human's rely on seeing more then smell.
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?
yes.
What type of nerve conducts impulses to the olfactory bulbs?
Sensory neuron
What is the receptor of the human nose?
The sensory receptors for your nose is the semicircular canals and the cochlea
What is the size difference in sheep brainstem and human brainstem?
In a sheep brain, the olfactory bulbs are much larger than in a human brain.http://wiki.answers.com/Q/How_do_the_sizes_of_the_olfactory_bulbs_of_the_sheep_brain_compare_with_those_of_the_human_brain"
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.
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.
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.

Does the rat or human have bigger olfactory bulbs?
Rat

Sensory neuron
What are the Inhibitory cells in the olfactory bulbs called?
Mitral Cells.
What is the receptor of the human nose?
The sensory receptors for your nose is the semicircular canals and the cochlea
What are the functions of the anterior commissure?
to connect the olfactory bulbs and the anterior part of the temporal lobes.
What cranial nerves are not associated with the brainstem?
The olfactory bulbs [I] and the optic nerve [II]
